RecomputeTargetSet sampled TerrainSampler.HeightAt (a 169-point biome blend kernel) 5x per column over the whole render distance on the main thread every chunk crossing (~1,445 calls = ~250k biome lookups), causing multi-frame hitches while moving. Memoize each chunk column's (min,max) surface range, reused across ticks and pruned to the horizontal window, so each column is sampled once. Exact (no terrain change); spike is amortized to a thin edge strip per crossing and zero when stationary.
VoxelEngine
A learning voxel engine written in C# (.NET 10) on top of OpenTK 4 / OpenGL 3.3.
Status
Early baseline. The current goal is rendering a single face-culled, textured 16×16×16 chunk that you can fly around with a free camera — the structural core the rest of the engine builds on.
Tech stack
- .NET 10 / C#
- OpenTK 4.9.4 — windowing, OpenGL bindings, and math
- StbImageSharp — texture (PNG) loading
Build & run
Requires the .NET 10 SDK.
dotnet run --project VoxelEngine.csproj
Once the baseline is running: WASD to move, mouse to look, Esc to quit.
Project layout
Core/ game window + loop
Rendering/ shader, texture, camera, chunk renderer (OpenGL)
World/ block model, registry, chunk, mesher (no OpenGL)
Assets/ shaders + texture atlas
The World/ layer is intentionally free of any OpenGL dependency so the voxel logic can
be unit-tested headless.
Roadmap
- Baseline: window, fly-camera, one face-culled textured chunk
- Procedural terrain (noise)
- Multiple chunks + frustum culling
- Player controller + AABB collision
- Block break / place
- Lighting
