Millions of facets with three.js?

Do you have exemples of very big scenes? I still have a laptop ^^

Let’s start with this one: three.js webgl - buffergeometry

It renders 160.000 triangles with a single draw call (you can evaluate WebGLRenderer.info.render in order to see these stats). It runs smoothly at 60 FPS on my five year old iMac.

And yes, I read the source code, and it was indeed an octree. Each object is stored on a cube, which itself is cut in 8 sub-parts, etc… If the object stand in the bounding box of a sub-part it is stored in the sub node, but if you have a very large object with a big bounding box, it is stored in a bigger cube.

This third party octree implementation is not used in any of the official three.js examples (three.js examples). So when you do a benchmark with them, forget any relations to octrees^^.
