3D file preview?

[Alex Davies]

I'd really like to be able to include STL files in my tiddlywiki, but actually supporting a new file type is a bit beyond me. It seems like it would be entirely doable using threejs, but a bit more challenging to make it happen "automatically" so that tiddlywiki doesn't try to show me several MB text files.

Any thoughts on how that could be accomplished? Something to do with mime type detection?

There is this :

Which has, I think, the ability to display STL files.

It's been on my to do list to look at and have a go but...

There there needs to be what, a display widget and and a parser?

Looking at the demos on that site, they all seem to be for .json files :(

But,

There is the .js program that sets up the scene, the lights etc.

There is the actual data file, in our case this would be the stl:

and then the tiddler containing the widget:

So I THINK it just needs something like this? https://stackoverflow.com/questions/11060261/what-is-the-preferred-method-for-loading-stl-files-in-three-js

but my brain melted at that point.

Would

be any help/ use?

Finally this, just because it looks shiny:

Any big brains out there any insight?

Here is a simple cube as STL if anyone can make this magic happen!

There is also this as part of the plugin:

Including 3d files in a wiki is a really neat idea. Man, I wish I had more time. Replaying so I can find the thread later. ;)

Best,

With the lazy-load tiddler on node-js supporting larger collections of files it seems like a potentially very useful tool.

Did you make any progress on this Alex?

[Alex Davies]

I'm afraid I haven't had any time to really work on this, and I don't anticipate getting more free time until after Christmas.

No worries. :) just wondering... And giving the thread a bump!
