Engine boundary
The folder separates WebGL2 backend detection, render loop, integer voxel data, greedy meshing, and packed vertex upload.
WebGL2 voxel foundation
Chunk.js starts with a WebGL2 voxel renderer built for NiceChunk.
This lab is isolated from the current game. It initializes WebGL2 directly, uploads an integer-packed voxel mesh, and keeps the renderer boundary ready for NiceChunk terrain.
Next migration target
The next step is TextureArray/atlas terrain materials, chunk streaming, and dirty chunk updates without touching gameplay logic first.
Performance rule
This prototype keeps runtime work small: one integer-packed static mesh, one shader program, one draw call, and no external texture assets.
