I would like to avoid popping in between LODs without rendering the large meshes twice. I am using the GPU renderer. I suspect this may entail a shaderMaterial, are there any example out there?

I believe virtual geometry might be what you look for. It allows gradual LOD and smooth reduction of geometry instead of the step-wise traditional LOD. [image] Virtually Geometric Showcase Hey Guys, I’ve been playing with the virtual geometry idea for a couple…

Thank you, I ll look into this.

I saw a YouTube livestream where Hugo Martin mentioned this in the idTech8 pipeline. It was further described in an interview featuring Billy Khan , which details lessons from overhauling Indiana Jones. Specifically, they don’t “do” (layman’s term) monolithic dynamic meshlets. They do “do” vertex-wa…

why not use the three.js simplifier and mipmapping examples, it’s straightforward no extra LOD meshes adding up to the file size? Demo

I think virtual geometry is amazing as a piece of tech, but I agree that 9 times out of 10 just a good set of discrete LoD will do the job just as well if not better. They will have close to 0 overhead, unlike virtual geometry and if done well - the user won’t notice any popping what-so-ever. Virtua…

Actually, a shader smoothing geometry transition is what i had in mind, but I havent yet found anything relatively easy to implement. Its all R&D, im very intyerested by all solutions, thanks!

[image] ventoline: relatively easy to implement That video chapter was dovetailed with destructible physics. So presumably LOD of rock vertex groups would be easy. But tweening an active demon arm breaking a board would be hard.

There was a paper, I forgot the name of it, I think it was written by Hugues Hoppe in 90s or early 2000s. The idea is based around parametric mesh simplification. That is - we use edge collapse to simplify a mesh - this is pretty standard, but we also record these transforms. That is - when we colla…
