Chunk LoD #64

Open Ralith opened 4 years ago

Ralith commented 4 years ago

As of #63, we're GPU bound on weak hardware. Using simplified geometry for distant chunks could help alleviate this. A very simple approach would be to run marching cubes on entire chunks, such that each chunk is a single cell, containing only a few triangles. Challenges include:

Preventing geometric gaps between LoD levels
Addressing the discontinuity between boxy and smooth terrain (if we retain boxy voxels)
Texturing the topologically very distinct geometry (if we retain boxy voxels)

transvoxel presents an elegant solution for LoD boundary stitching with marching cubes.

This should not be addressed before #41, which will reduce the number of triangles rendered dramatically and shift the bottleneck.

@patowen's benchmarking currently indicates that the rendering time for voxels is utterly insignificant compared to CPU costs, so we should not invest in chunk LoD for the foreseeable future.
