Another new update

[Peter Grosserhode]

It is still being checked by the PlayStore

The zoom issues on objects that are far away from the pivot point have been 90% fixed. That means if you try to zoom in to an object that is close to the edge of the splat it seems to slow down the zoom and nearly hits a wall (progress nearly stops) but if you keep trying to zoom it will switch after a few attempts into a different mode and it will go into a very fast zoom mode and lets you then zoom all the in and thru the object.
In another release I will try to make this transition less obvious.

Next bi update I worked on all morning was the new .spz Version 4 implementation, that was just released 2-3 days ago by Niantic Spatial   https://www.nianticspatial.com/blog/spz4?utm_source=substack&utm_medium=email

Very promising compression. Had a lot of issues, but they seem to be all fixed now.

So please play with that. The link above leads also to a converter at the bottom of the page to convert .PLY into .SPZ , automatically Version 4.

Big compression and still pretty good in detail unless zoomed in too much.

I also noticed my phone getting warm and battery levels dropping faster then normal. Implemented some changes to optimize the app. Here are short summary:

• Idle frame throttling — After 500ms of no interaction (touch/mouse), rendering drops to ~1 FPS to save battery. Resumes instantly on touch with 3 "settle frames" so the sort catches up smoothly.

• Point budget decimation — Files with >5M splats are stride-sampled (every 2nd/3rd/Nth point) to keep GPU load manageable. SH textures are now also correctly decimated to match.

• Model Info — When decimation is active, the Splat Count row shows "rendered / total" (e.g., "2,500,000 / 10,000,000")

Please play with the app, try different supported models and let me know if you run into more issues. 
Thanks again to Singh D for finding that beautiful Colmar Castle that really showed a big limitation of the earlier app.

amazing speed at which you are adding & improving the app. Glad to help with feedback. 

- with the update for .spz ver.4. but the older versions of spz will be supported right ??
as most gaussian players/ exporters have not supported spz ver.4 yet..

Thank you. AI makes it possible now to go thru all these changes very fast. Before the latest update I had 4 more versions in between. Most of them had serious issues with the rendering quality. It took a few tries for the AI to figure out the correct math in all the planes to get it correct. Sometimes I use 2 different AIs and they agree and its still wrong ;)
Yes, the previous versions of SPZ are still supported. I also changed the "Home Screen" and added them to the file types that are supported. So .spz version 1-4 also.

I would be interested to know what kind of Android phones everyone is using?
