# Voxel Engine Reference

C# / OpenTK 4 Voxel Engine (Minecraft clone). 

## Core Systems
- **Rendering**: SSBO-based (Shader Storage Buffer Objects) for packed face data and GPU meshing.
- **Data**: 1D Flat arrays for blocks, bitwise indexing for speed.
- **Updates**: Dirty-flagging for chunk and neighbor mesh rebuilding.

## Performance Notes
- Use `UpdateNeighborsAtBoundary` to mark adjacent chunks dirty.
- Call `RebuildDirtyChunks` at the end of the update loop.
- Avoid per-block `GL.BufferSubData` calls, batch into one SSBO update.
