Wonderbox-inspired lighting overhaul across all 3 pixel shaders:
- Hemisphere ambient (sky blue above, warm brown below) replaces flat ambient
- RT shadows lerp toward blue-violet tint instead of plain darkening (factor 0.55)
- Rim light (fresnel) with warm golden color on silhouettes (30% on vegetation)
- Soft exponential tone mapping + saturation boost in final post-process pass
- CB parameters for all lighting values (skyAmbient, groundAmbient, shadowTint, etc.)
- Fog color/density centralized from CB instead of hardcoded per-shader
- Screenshot mode (CLI "screenshot"): fixed camera, AO convergence, auto-capture
- AO noise stability: world-space hash using voxel center + tangent-axis frac position
- AO distance-weighted falloff: continuous occlusion values instead of binary hit/miss
Rewrote voxelSmoothPS.hlsl to derive a dominant face axis from the smooth
normal, then use the exact same neighbor verification as voxelPS.hlsl:
faceU/faceV tangent tables, stair-priority getNeighborMat(), face-aligned
fractional coords, blendZone 0.25, corner attenuation, bleedMask checks.
Added generateDebugSmooth() with 11 isolated test configurations
(smooth↔blocky transitions, staircases, surrounded patches, reference
blocky pairs). Launch with: BVLEVoxels.exe debugsmooth
Mega-buffer architecture replacing per-chunk GPU buffers:
- Single StructuredBuffer<PackedQuad> for all chunks (2M quads, 16 MB)
- StructuredBuffer<GPUChunkInfo> with per-chunk metadata (position, quad offsets, face groups)
- VS reads chunk info via push constants (b999) for driver-safe chunk indexing
- CPU frustum culling with wi::primitive::Frustum + AABB per chunk
- Quads sorted by face direction in greedy mesher (faceOffsets/faceCounts)
- GPU frustum + backface cull compute shader (voxelCullCS.hlsl)
- GPU binary mesher compute shader baseline (voxelMeshCS.hlsl)
- Indirect draw buffers and timestamp query infrastructure
- README with build instructions and project architecture
