8 hours	feat: GPU procedural Phase 4 - texture composition	skal
	Multi-input composite shaders with sampler support. - Dynamic bind group layouts (N input textures + 1 sampler) - dispatch_composite() for multi-input compute dispatch - create_gpu_composite_texture() API - gen_blend.wgsl and gen_mask.wgsl shaders Guarded with #if !defined(STRIP_GPU_COMPOSITE) for easy removal. Tests: - Blend two noise textures - Mask noise with grid - Multi-stage composite (composite of composites) Size: ~830 bytes (2 shaders + dispatch logic) handoff(Claude): GPU procedural Phase 4 complete
9 hours	feat(gpu): Phase 2 - Add gen_perlin and gen_grid GPU compute shaders	skal
	Complete Phase 2 implementation: - gen_perlin.wgsl: FBM with configurable octaves, amplitude decay - gen_grid.wgsl: Grid pattern with configurable spacing/thickness - TextureManager extensions: create_gpu_perlin_texture(), create_gpu_grid_texture() - Asset packer now validates gen_noise, gen_perlin, gen_grid for PROC_GPU() - 3 compute pipelines (lazy-init on first use) Shader parameters: - gen_perlin: seed, frequency, amplitude, amplitude_decay, octaves (32 bytes) - gen_grid: width, height, grid_size, thickness (16 bytes) test_3d_render migration: - Replaced CPU sky texture (gen_perlin) with GPU version - Replaced CPU noise texture (gen_noise) with GPU version - Added new GPU grid texture (256x256, 32px grid, 2px lines) Size impact: - gen_perlin.wgsl: ~200 bytes (compressed) - gen_grid.wgsl: ~100 bytes (compressed) - Total Phase 2 code: ~300 bytes - Cumulative (Phase 1+2): ~600 bytes Testing: - All 34 tests passing (100%) - test_gpu_procedural validates all generators - test_3d_render uses 3 GPU textures (noise, perlin, grid) Next: Phase 3 - Variable dimensions, async generation, pipeline caching Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
9 hours	feat(gpu): Add GPU procedural texture generation system	skal
	Phase 1 implementation complete: - GPU compute shader for noise generation (gen_noise.wgsl) - TextureManager extensions: create_gpu_noise_texture(), dispatch_noise_compute() - Asset packer PROC_GPU() syntax support with validation - ShaderComposer integration for #include resolution - Zero CPU memory overhead (GPU-only textures) - Init-time and on-demand generation modes Technical details: - 8×8 workgroup size for 256×256 textures - UniformBuffer for params (width, height, seed, frequency) - Storage texture binding (rgba8unorm, write-only) - Lazy pipeline compilation on first use - ~300 bytes code (Phase 1) Testing: - New test: test_gpu_procedural.cc (passes) - All 34 tests passing (100%) Future phases: - Phase 2: Add gen_perlin, gen_grid compute shaders - Phase 3: Variable dimensions, async generation Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
