What do you want to see from Cesium in 2019?

[Gabby Getz]

Hi everyone!

2018 was a big year for the Cesium team. We saw the addition of some long awaited CesiumJS features and improvements, as well as the release of our Cesium ion platform with support for 3D tiling. We want to make 2019 just as productive!

Let us know what is important to you for Cesium, 3D Tiles, glTF, or beyond. Some topics already on our radar include:

• Improving 3D Tiles streaming performance
• Terrain and imagery streaming improvements, #7061, leading up to terrain on by default
• Polylines, #7437, and textured ground primitives, #7434, on 3D Tiles 
• Interoperability with other WebGL engines
• Improved label quality, #5022
• Subsurface/undersea visualization, #6047
• TypeScript definitions, #4434
  
• ES6 modules

Feedback on the Cesium ion SaaS platform, 3D Tiling Pipeline, or 3D analytics SDK is more than welcome as well. For 2019, we're looking at:

• Improved BIM/CAD support
• Vector data support
• More GPU-accelerated analytics

We want to hear from you! Any and all feedback is valuable. Is there something else you want to see? Are any of the above features applicable to you? Even a +1 for a specific feature will help. We'll keep this thread open all year, but we're hoping to get the majority of your input in by the end of January.

Thanks and happy New Year!

Gabby

The biggest thing for us would be better performance for dynamic map features. We pretty much can't use the Entity system because its too slow. There are also issues with polylines and other shapes flickering when updating.

Need to be able to update lots of polylines (add, remove, move points) as well as other shapes.

Our software currently has several workarounds using undocumented private variables / functions to try and fix performance issues, especially related to updating polylines. I've noticed when looking at the performance tab in Chrome, Cesium appears to be re-creating geometry and allocating buffers all the time instead of re-using them.

Not sure if it would be possible to take advantage of the new OffscreenCanvas support to move all the Cesium rendering code into a web worker?

[Omar Shehata]

This is super valuable feedback Scott, thanks for sharing this.

I'm aware of a few flickering issues (here, and here). I don't think we have a lot of documented cases of performance issues. If you have the time it'd be awesome to get more details in a GitHub issue. Especially hearing about your application requirements would be very useful (is it just a small subset of polylines that needs to dynamically move at any given time? Is it all of them? Are they all in view?) as well as what you had to do to make it faster I'm sure would be very helpful to the community.

[ihsan...@gmail.com]

I wish html support on labels :)

[Aristeidis Bampakos]

+1 for Typescript definitions and ES6 modules.

It would also be great if we could have detailed documentation on the use of https://api.cesium.com/ API (related issue on Github https://github.com/AnalyticalGraphicsInc/cesium-ion-community/issues/29)

Thanks and happy new year!

[Gabby Getz]

Thanks Scott, ihsanergun, and Aristeidis!

So far we have some CesiumJS suggestions for improving entity performance and HTML support in labels.

The api.cesium.com API is open, and we already have some integrations using it. We'd love to see more and adding documentation would definitely support that!

Great suggestions so far. Keep the ideas coming!

Hi Gaby & Omar;

+1 on your radar.

Some ideas:

On the classification topic :

Capacity to classify an entity in a similar manner we can do with terrain and 3D Tiles: ex : Cesium.ClassificationType.ENTITY

• if an entity is placed (statically or dynamically) into an classification volume, classification is applied also on the entity.
• classificationType could becomes a list in such case [Cesium.ClassificationType.ENTITY,Cesium.ClassificationType.TERRAIN]
  

Capacity to combine properties from both classification features & the classified feature and apply styling on the combined set of properties on the classified feature.

• The classified feature properties are extended by the classification feature(s)  it belongs to (inside).
• REPLACE,EXTEND,IGNORE option to help to drive what to do 

Happy New Year;

Pascal

Hi, if the MaterialAppearance is supported as a attribute for GroundPrimitive would be a cool thing.

 That sounds like it could definitely be pretty useful, especially since I know a lot of people use Cesium for that kind of data. Do you have any links that show what this sort of effect should look like? And were you thinking of implementing it as a shader/material/post process or as dynamic geometry/entities? It might be cool to document it in a GitHub issue and see if anyone wants to implement it.

Thanks, some addon on classification

One typical use of a classification tileset is to add information over a point cloud tileset (poor in semantic) or the terrain. Hereafter  an example (vctr over pnts).

But for example if the classified tileset has some properties (like buildings below) it could be interesting to :

- temporary combine properties from a building feature & the active classification feature it belongs to.

- apply a dedicated style on the buildings  to show a particular rule based on a mixed of both building properties and the active classification feature properties it belongs to, but keeping green terrain,vegetation and buildings which don't follow the styling rule.

Perhaps there are some way to already do it with the OOTB, but I didn't investigate as of now.

[jere.m.v...@gmail.com]

Hey

If there will be an option to switch shading on/off for 3D tiles buildings, it would be awesome.

[pollux]

Add new one ,the GroundPrimitive should be support more geometry ,such as custom geometry(Cesium.PrimitiveType.TRIANGLES).By then, meteorological and environmental data which saved as grid could be add in Cesium.

Hi everyone!

[Omar Shehata]

I know a few people have requested custom geometry before, and you can do this right now in Cesium if I'm not mistaken, it's just not documented very well. 

Do you have any links or references of what this kind of data looks like? Or are there any standard formats for it?

[pollux]

Just like this grid picture , the river boundary divided into many triangles or rectangles(a rectangle consist of two trangles),each vertice in trangle has  a value which represents water temperature.

Now,I want to draw water  temperature  by custom geometry and GroundPrimitive on terrian ground,but It seems current version doesn't support custom geometry for GroundPrimitive .

DeveloperError: Not all of the geometry instances have GroundPrimitive support.

Another example for weather data:

I would love to see a couple things:

1) Improved performance for paths. When I have dozens of paths each with hundreds of points, performance takes a really bad hit. I think this issue may address it: #2310.

2) Support for partial ellipsoids (pull request #5995). I think it is almost ready for prime-time, but if the team could help get it past the finish line, that would be great!

Thanks!

[Omar Shehata]

Thanks for the feedback Steven! For the path performance, I see there's some technical discussions on the issue about it (https://github.com/AnalyticalGraphicsInc/cesium/issues/2310). One thing I try to learn from the forum is the context for all these features. Can you share a bit about how you use these paths in your application(s)? Do they tend to span hundreds of kilometers or more local areas? Are they dynamic/changing from frame to frame? 

[Mark Erikson]

Would love to finally see dynamic billboard update handling / texture reuse (refs: https://github.com/AnalyticalGraphicsInc/cesium/issues/2094 , https://github.com/AnalyticalGraphicsInc/cesium/issues/2319 ).

[stevenr...@gmail.com]

Hey Omar, my paths tend to span thousands of kilometers. They are dynamic and are updated as new data becomes available.

[Gabby Getz]

Thanks everyone! There's been some great ideas and use cases suggested here. Recently I see an emphasis on improving performance for time dynamic data.

The end of January is almost here! We're going to start planning our year, so get your ideas in if possible. Even just a vote or a +1 to show what's important to you is a huge help for us.

[prashanth...@gmail.com]

Hi,

The Draw helper plugin provided works fine but for editing entities, there is no option.

Adding the following options will be of great help!
1. Editing point entities to make them drag-able would be of great help.
2. Editing of polyline and polygon vertices to change shape and also move the whole entities.

Thanks!

[Omar Shehata]

Are you referring to the drawing on terrain Sandcastle example?

https://cesiumjs.org/Cesium/Build/Apps/Sandcastle/?src=Drawing%20on%20Terrain.html

Editing other entities should work the same way with some additional custom application code. We do have some editing widgets and tools in the commercial ion SDK though:

https://cesium.com/ion-sdk/

[prashanth...@gmail.com]

Hey Omar,

Drawing on terrain is not an issue, what i meant by editing entities is that...

I am adding a billboard graphic as entity on map, on click of edit button I should be able to do some basic editing like move the billboard using the cursor. Have searched on the net but haven't found any solution. Is that option available?

[Omar Shehata]

It is not built into the library, but this is something you can build into your application since it can be unique to your use case. So you can write code to listen for mouse clicks/button presses, and then move the billboards etc.

It might be cool to be able to do that when you upload your data to Cesium ion though, to annotate and construct scenes just by clicking and editing like that.

[prashanth...@gmail.com]

Yes Omar, I tried that thing using screen space event functionality and it worked perfectly fine.

Thanks for the suggestion :)

[Gibran P]

It would be great to be able to specify an alternate texture for a terrain if the angle is above a certain point. so for the above (where I've simulated a forest by adding 60 feet to the terrain with a cliff-like 90-degree dropoff), I would specify a texture from the "side" of the woods, and ideally I could specify the dimensions for it so it tiles at appropriate times, like so:

This would also be applicable for photogrammetry that might be missing certain angles, or non-photogrammetric rendering of something like the Grand Canyon, where we have an accurate DEM and an accurate nadir aerial to texture the tops, but not the sides- where we could add in a generic rock face or something of that nature.

[Qandeel Abbassi]

It would be awesome if rotation of labels and billboards can be fixed. I don't mean locking rotation along a particular axis but rather no rotation at all.

[Omar Shehata]

This sounds like a really interesting idea Gibran! In the long term, I think this can be solved by folding terrain and imagery into 3D Tiles, like this Q &A paragraph in the 3D Tiles repo describes:

https://github.com/AnalyticalGraphicsInc/3d-tiles/blob/master/Q-and-A.md#will-3d-tiles-include-terrain

That way, you could control exactly what the imagery looks like on terrain tiles since they could be streamed together.

[Omar Shehata]

That sounds more like just a textured polygon defined in 3D space that doesn't rotated to face the camera, is what you mean?

I think the new CoplanarGeometry can have textures applied to it. It's only available via the Entity API right now though:

https://github.com/AnalyticalGraphicsInc/cesium/pull/6769

[Qandeel Abbassi]

This might help in creating fixed rotation billboard but what about fixed rotation text

[milcode9]

I would also like to see improved performance with 1) the entity api 2) The shading of hundreds of overlapping entity polygons in which polygons are added and removed from the group of overlapping polygons. I describe this use case that slows down both drawing and frame rate in the following post:

3 thousand entities slowing down drawing of entire application

I would add an implementation for WFS services (Web feature services) in the same way WMS or WMT-S are already implemented.

[David Romeuf]

Really good work, congratulations for the developers. Can you add a control to display in stereoscopy, anaglyph, crossed, ...

best regards.

[Gibran P]

Great work folks!

The ability to label polylines the way a basemap generator like Geoserver does would be killer. Or just a way to lock the rotation of a label (and let it be aligned to the ground the way I could do with billboards), so I could place it next to a polyline.

[mcrummey]

Ability to import autodesk files like DWG DXF etc...

[Alan Rose]

Two features come to mind for me.

VR. It would be nice to have the ability to switch mode like 2D and 3D into VR with full motion controller support as well. Much like the WebVR demo at Babylon.js

Also the ability to specify a lat long bounding box that tells cesium to reload the terrain (maybe image as well) tiles inside the box. This would help with applications that have dynamic terrain elevations. 

 

[cav...@gmail.com]

HI  
  Thank you very much for providing a very good framework for your team. I would like to ask when cesium can support Vector data support and More GPU-accelerated analytics

[Omar Shehata]

Cesium does already support vector data as CZML, GeoJSON or through the Entity API. Adding a vector format to 3D Tiles would be the next step in being able to visualize much larger vector data sets, you can see the roadmap here https://github.com/AnalyticalGraphicsInc/3d-tiles/issues/25.

There does exist analytics built on top of CesiumJS available commercially that you can check out here: https://cesium.com/ion-sdk/

[william....@gmail.com]

+1 for Custom builds of Cesium (the Entity API is unused by us in addition to service implementations such as WMS, ArcGIS, etc.), Polyline improvements, and offscreen canvas support.

[Omar Shehata]

Can you elaborate a bit on this William? For custom builds, do you mean the ability to create your own materials/primitives? Are there specific things you're trying to do now with Cesium that are difficult or not possible?

Also, can you tell me a bit more about your use cases for offscreen canvases?  

[prashanth...@gmail.com]

Hey,

I have an ESRI REST map service of a layout which requires to login every time it loads. In ESRI, we use Java proxy to avoid logging in on the front end. Similarly in Cesium, is there an option to bypass logging in front end?

I have used ArcGisMapServerImageryProvider to load that layout map service but the tiles didn't load. There is an optional parameter called "proxy" but I'm not able to use it due to lack of documentation. Can you please help me out here?

Thanks,
Prashanth

[Omar Shehata]

We do have an issue for export scenes from CesiumJS as CZML:

https://github.com/AnalyticalGraphicsInc/cesium/issues/7372

I think that would be the first step, and I can imagine building on top of that to convert the captured CZML to any of those formats. Can you describe your use case here a bit? Are you using CesiumJS to create a scene to then display in other programs, or is the goal to edit the exported geometry in other programs, and then perhaps be able to visualize back in Cesium?

It pops up every year, but I'll just float the idea of supporting multiple terrain providers again.

Our use-case is representing various land development scenarios that might range from single properties through to 100+ subdivisions. Within a single neighborhood there could be multiple sites each with different plans that we would want to review, so in this case pre-generating the the different permutations isn't really an option.

Thanks,

Steven

Hi everyone!

2018 was a big year for the Cesium team. We saw the addition of some long awaited CesiumJS features and improvements, as well as the release of our Cesium ion platform with support for 3D tiling. We want to make 2019 just as productive!

Let us know what is important to you for Cesium, 3D Tiles, glTF, or beyond. Some topics already on our radar include:

• Improving 3D Tiles streaming performance
• Terrain and imagery streaming improvements, #7061, leading up to terrain on by default
• Polylines, #7437, and textured ground primitives, #7434, on 3D Tiles 

• Interoperability with other WebGL engines
• Improved label quality, #5022
• Subsurface/undersea visualization, #6047

• TypeScript definitions, #4434
  
• ES6 modules

Feedback on the Cesium ion SaaS platform, 3D Tiling Pipeline, or 3D analytics SDK is more than welcome as well. For 2019, we're looking at:

• Improved BIM/CAD support
• Vector data support

• More GPU-accelerated analytics

[xc z]

+1 ES6 modules.

Please rewrite all codes in ES6

React Native compatibility, really would be amazing porting native apps with Cesium on to the mobile and native platforms.

[Alan Rose]

I take it this wish list still valid for 2019, or maybe it should be 2020 :)

The cesium inspector is a great development tool and I would like to see another feature added if it doesn't exist already.

Recently I added vector normals to my custom quantized mesh tiles, however the shading doesn't always match what I think should happen.

It would be nice if we could use the inspector to see the terrain tiles vector normals for debugging shading

[Omar Shehata]

We certainly are still keeping our eyes on this list, and appreciate all the suggestions here!

I don't think there's currently an easy way to see the normals, other than perhaps using the globe shading (https://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Globe%20Materials.html) so that could be a useful feature.

[sean...@gmail.com]

It would be much appreciated with our cesium-react-webpack-jest setup if Cesium had:

• ES6 Module import compatibility (So that it can work with Jest without a workaround for AMD/requireJS)
• Jest testing library compatibility

Matt was actually just looking into ES6 support last week! Still no timeline for when that will happen yet, but this issue documents what it would take and what progress we have:

On the topic of vector data, are there any plans for supporting Vector tile basemaps? i.e the basemaps mentioned in this esri blog post?

[Omar Shehata]

I'm not sure, is there a specification of this released somewhere? Or some example datasets?

[Abhi Sundu]

Thanks for the response. There are some examples here at the bottom of the page. As far as a specification goes, ESRI mentioned they would likely re-use Mapbox's spec in their blogpost a while back, I'm not 100% sure if they stuck with that though.

The mapbox vector tile specification can be found here. 

[Omar Shehata]

Thanks for the links! We do have an issue open for adding support for vector tiles here: https://github.com/AnalyticalGraphicsInc/cesium/issues/2132. So I imagine that could be a step towards supporting those basemaps then.

When you say the entity framework is too slow what do you mean. I know for me the enitity framework seems to bog the system down and crash when there are thousands of entities on the globe

The biggest thing for us would be better performance for dynamic map features. We pretty much can't use the Entity system because its too slow. There are also issues with polylines and other shapes flickering when updating.

Need to be able to update lots of polylines (add, remove, move points) as well as other shapes.

Our software currently has several workarounds using undocumented private variables / functions to try and fix performance issues, especially related to updating polylines. I've noticed when looking at the performance tab in Chrome, Cesium appears to be re-creating geometry and allocating buffers all the time instead of re-using them.

Not sure if it would be possible to take advantage of the new OffscreenCanvas support to move all the Cesium rendering code into a web worker?

We created an extendedEntity framework that we used for high entity count scenarios. Check this out:

https://celestrak.com/cesium/orbit-viz.php?tle=/pub/TLE/catalog.txt&satcat=/pub/satcat.txt&orbits=1&pixelSize=3&samplesPerPeriod=90&referenceFrame=1

I submitted a pull today for one of the techniques we used. Still working on formalizing the rest of it so that the API is coherent.

[Omar Shehata]

Thanks for contributing this back to CesiumJS TJ Koury! This is definitely going to be useful for a lot of people in the community. Looking forward to more entity performance improvements.

[crazysp...@gmail.com]

hi thank you for your post , hope to see new updates beacuse now i am facing low performance of the map feature that needs to be updated

[Yordan Yanakiev]

I would like to see it switched to WebAssembly in order to gain at least 5-10 times higher performance, and if possible Blazor integration.

Hey is there anyway to use what you have made? Our globe crashes at 40k entities on the screen. Wondering how you made them so efficient and if we can use your code?

You can use point primitives to lessen the computational load each tick, then manually update their positions.

[Andrew Hinson]

Ok thank you! I can give that a try. For every LLA we receive we add a new point. I can try to switch the entity out for a point primitive

Looks like the only remove function requires the primitive itself: https://cesiumjs.org/Cesium/Build/Documentation/PointPrimitiveCollection.html#remove

Feel free to start a new thread if you have more questions about point primitives just so we can discuss it more there.

[Majid Hojati]

I expected a dynamic datasource loading for 2d data bases on xyz. many years ago

[Omar Shehata]

Do you mean data that's dynamic over time (which you can already do with CZML) ? If not, can you describe your use case more? 

[Majid Hojati]

Hi, Not over time something like geojson datasources but being able to load data for each tile. Like WMS layers but instead of loading images we load vector (geojson, mvt and so on)

Every time I want to load a set of vector layers on cesium I face this limitation to load them base on tiles. I know you have already 3d vector tiles but for a free use of cesium or education purposes using vector tiles servers is not possible. The custom datasource also does not work in such case since we have to load data once and it does not work for large amount  of data

[Benjamin Mur]

What i would like to see in 2020 ?

- Negative terrain under the sea ? With sea level representation !

- Fixing the zoom in/out issue when a billboard is centered to the view

Am i too greedy ? ^^

[Benjamin Mur]

HO ho !!!

And also fixing the number of cesium viewers you can instanciate in one page !! Dynamically !

I mean, creating one, deleting, and creating another...only works 16 times !

After, WebGL crashes ! So a fix to this issue would be nice ^^

[ta...@edgybees.com]

It definitely was a great year thank you for your dedicated work!

I think the following features will be extremely valuable -

- z-ordering for labels and billboards.

- Improvement in labels and billboards clamp to ground functionality - currently, toggling the visibility of those entities freezes the scene.

- Set disableDepthTestAgainstTerrain, per entity, instead of for the entire scene.

[Omar Shehata]

Thanks for the kind words Tamar!

The z-ordering is indeed a popular request (I believe you've found the GitHub issue but if anyone else is looking for it: https://github.com/AnalyticalGraphicsInc/cesium/issues/4108)

For the other two, I'm not aware of this entity freezing issue, and controlling depth test of entities individually could be useful. I think you can do something similar with disableDepthTestDistance on some entities, depending on your use case (at the very least perhaps that code can be extended for depthTestAgainst terrain reasons). If you can start a new forum thread with some more details about your use case I'd be happy to suggest workarounds or open a feature request/bug report if one doesn't already exist.

[ta...@edgybees.com]

Hey Omar :)

I saw the open issue and well aware that it is a popular request. I still hope it will be addressed in 2020.

I need the depth test controlling mainly for polygon and polyline entities, is there a workaround for it as well? 

Finally, regarding the freezing issue, please see the following sample - Clamped to ground visibility toggle freezing

[Omar Shehata]

Hey Tamar,

I'm fairly certain the clamping causes this freezing due to the Globe picking being the bottleneck (which is what computes the terrain height at each given location). We just opened an issue for this here: https://github.com/AnalyticalGraphicsInc/cesium/issues/8481

[ta...@edgybees.com]

I guess it makes sense, thanks for the update :)
