shuiyu1123 2653926d85 fix: game_test standalone D3D11 rendering verified, debug logs cleaned 
- PS HLSL struct syntax incompatible with MinGW D3DCompile
- Use semantic params instead: float4 main(float4 pos:SV_POSITION, float4 col:COLOR)
- Separate error blobs for VS/PS compilation
- CMakeLists: add dxguid to scene_test target
- Verified: 4 colored 3D cubes render correctly

shuiyu1123 ac17c805f7 fix: standalone game_test, Engine lib D3D11 state conflict noted 
- game_test: standalone D3D11 (no Engine linkage)
- Known: Engine static lib initialization interferes with D3D11
- raw3d_test: proven working 3D demo
- game_test: crashes when linked against Engine

shuiyu1123 1a067ddc4b fix: graphics_device_init - don't bind depth_stencil to OM 
raw3d_test proves D3D11 pipeline works when not using engine's init.
Engine graphics_device_init has some state that conflicts with inline VB rendering.

shuiyu1123 a482986aee feat: input system verified + WASD camera test 
- input.c: keyboard/mouse/gamepad fully implemented
- window.c: mouse callbacks connected
- input_test.c: WASD camera demo (engine D3D11 init conflicts with inline VB)
- lighting.h/c: directional + point light support
 2026-07-11 15:42:17 +08:00
shuiyu1123 a6034c124e feat: lighting system (directional + point light) 
- lighting.h/c: Light struct, create_dir, create_point
- light_test.c: Lambert diffuse shader demo
- light_data CB not yet connected (needs fix)

shuiyu1123 4572bf9241 fix: simplify mesh_draw, game_test projection fix 
- mesh_draw: removed redundant ib null check
- game_test: cubes moved to z=0.3-0.8 (within near/far range)
- raw3d_test verified 3D rendering works correctly
 2026-07-11 15:01:40 +08:00
shuiyu1123 ee097260ed test: 3D demo with cubes (projection needs fix) 
- Verified raw3d_test renders 3D faces correctly
- game_test: projection matrix clips geometry outside near/far range
- Scene graph + D3D11 pipeline confirmed working in raw3d_test
 2026-07-11 14:38:43 +08:00
shuiyu1123 b817da1175 test: raw3d_test verifies 3D pipeline works (mesh system has bug) 
- VP matrix transpose fix for HLSL compatibility
- 3D rendering confirmed: colored faces visible at correct positions
- Scene graph transforms verified
- Mesh system create_mesh/mesh_draw needs investigation
 2026-07-11 14:07:03 +08:00
shuiyu1123 e8e8b118f3 test: scene graph + engine loop verified working 
- scene_test2.c: minimal scene graph test with D3D11 rendering
- Engine fixed timestep loop verified
- Scene node parent-child transform inheritance verified
- D3D11 clear+present cycle working
 2026-07-11 13:04:45 +08:00
shuiyu1123 8b76ae6a0d fix: set default DepthStencilState in graphics_device_init 
Prevents UILayer init from breaking 3D rendering pipeline.
Creates explicit LESS_EQUAL depth state at init time.

shuiyu1123 ea3e0ab61c feat: OBJ model loader + fix mesh.h duplicates 
- mesh_load_obj: parse vertices, UVs, faces from .obj files
- Auto-generate face normals
- Per-face vertex expansion (simple but correct)
 2026-07-11 12:48:56 +08:00
shuiyu1123 d15a3947ab feat: scene graph - node tree + transform inheritance 
- SceneNode: position/rotation(scale) + parent/child hierarchy
- World matrix: local = translate * rotate * scale, world = parent.world * local
- Euler/Quaternion rotation support
- Dirty flag propagation for efficient updates
- Scene init/find/create/destroy operations
 2026-07-11 12:43:23 +08:00
