Any idea what are the challenges to implement SVO in js? preferably inside an engine like voxel.js?

I can think of a few:

  1. online SVO buildup: some steps rely on GLSL atomic operations.
  2. 3D texture support for storing bricks: Though 3D texture could be emulated by layered texture, I have no idea what's the performance impact.

  1. voxel.js is based on three.js that has WebGL as a preferred mode. I am not sure if this would solve the problem, but it presents hope.
  2. for my particular problem, I would use just plain semi-transparent colors. I would love to octree the human body as per http://sliced.ro/smp/nav2d.php demo. (By the way: the digital model is coming from South Korea and I am in negotiations with China for their dataset for the human body)

If your target is to render static scene, then precomputing the SVO on CPU is an option.
But the resulting data size might be big and require a lot of time for transferring it from server to client.
