StillHammer	262eef377e	feat(BgfxRenderer): Phase 5.5 - Sprite shader with instancing and texture support ... - Create proper sprite shader (vs_sprite.sc, fs_sprite.sc) with GPU instancing - SpriteInstance struct now 80 bytes (5 x vec4) for GPU layout compatibility - Add BufferDesc::Layout enum (Raw, PosColor, InstanceData) for proper vertex layouts - BgfxDevice creates correct VertexLayout based on buffer type - SpritePass uses PosColor layout for quad vertices (Position + Color0) - Instance buffer uses 5 x vec4 layout (TexCoord7-3) for i_data0-4 - Add texture support with v_texcoord0 interpolation from instance UVs - Create default white 1x1 texture fallback - Compile shaders for SPIRV (Vulkan), GLSL (OpenGL), and Metal Visual test confirms sprites render correctly at ~545 FPS. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-11-27 19:27:25 +08:00
StillHammer	4a30b1f149	feat(BgfxRenderer): Complete Phase 4 - ShaderManager integration ... - Refactor ShaderManager to use RHI abstraction (no bgfx:: exposed) - Implement Option E: inject ShaderHandle via pass constructors - SpritePass/DebugPass now receive shader in constructor - RenderPass::execute() takes IRHIDevice& for dynamic buffer updates - SpritePass::execute() updates instance buffer from FramePacket - Integrate ShaderManager lifecycle in BgfxRendererModule - Add test_22_bgfx_sprites.cpp (visual test with SDL2) - Add test_22_bgfx_sprites_headless.cpp (headless data structure test) - Update PLAN_BGFX_RENDERER.md with Phase 4 completion and Phase 6.5 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-11-26 22:27:19 +08:00
StillHammer	1443c1209e	feat(BgfxRenderer): Complete Phase 2-3 with shaders and triangle rendering ... Phase 2 - RHI Layer: - Fix Command struct default constructor for union with non-trivial types - Add missing mutex includes in ResourceCache.cpp - Fix const_cast for getChildReadOnly in SceneCollector Phase 3 - Shaders & Visual Test: - Add ShaderManager for centralized shader loading - Embed pre-compiled shaders (OpenGL, Vulkan, DX11, Metal) - Add test_20_bgfx_rhi: 23 unit tests for RHI components - Add test_21_bgfx_triangle: visual test rendering colored triangle Test results: - RHI unit tests: 23/23 passing - Visual test: ~567 FPS with Vulkan renderer 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-11-26 16:43:17 +08:00
