# Voltex Engine - 작업 현황
|
|
|
|
## 완료된 Phase
|
|
|
|
### Phase 1: Foundation (삼각형 렌더링)
|
|
- voltex_math: Vec3
|
|
- voltex_platform: VoltexWindow, InputState, GameTimer
|
|
- voltex_renderer: GpuContext, Vertex, shader, pipeline
|
|
- examples/triangle
|
|
|
|
### Phase 2: Rendering Basics
|
|
- voltex_math: Vec2, Vec4, Mat4 (transforms, look_at, perspective, orthographic)
|
|
- voltex_renderer: MeshVertex(+tangent), Mesh, depth buffer, OBJ parser, Camera, FpsController
|
|
- voltex_renderer: Blinn-Phong shader, BMP texture loader, GpuTexture
|
|
- examples/model_viewer
|
|
|
|
### Phase 3a: ECS
|
|
- voltex_ecs: Entity(id+generation), SparseSet<T>, World(type-erased storage)
|
|
- voltex_ecs: query<T>, query2<A,B>, Transform component
|
|
- examples/many_cubes (400 entities, dynamic UBO)
|
|
|
|
### Phase 3b: Scene Graph
|
|
- voltex_ecs: Parent/Children hierarchy, add_child/remove_child/despawn_recursive
|
|
- voltex_ecs: WorldTransform propagation (top-down)
|
|
- voltex_ecs: Scene serialization (.vscn text format), Tag component
|
|
- examples/hierarchy_demo (solar system)
|
|
|
|
### Phase 3c: Asset Manager
|
|
- voltex_asset: Handle<T>(generation), AssetStorage<T>(ref counting), Assets(type-erased)
|
|
- examples/asset_demo
|
|
|
|
### Phase 4a: PBR Rendering
|
|
- voltex_renderer: MaterialUniform (base_color, metallic, roughness, ao)
|
|
- voltex_renderer: Cook-Torrance BRDF shader (GGX NDF + Smith geometry + Fresnel-Schlick)
|
|
- voltex_renderer: Procedural UV sphere generator
|
|
- voltex_renderer: PBR pipeline (3→4 bind groups)
|
|
- examples/pbr_demo (7x7 metallic/roughness sphere grid)
|
|
|
|
### Phase 4b-1: Multi-Light
|
|
- voltex_renderer: LightData (Directional/Point/Spot), LightsUniform (MAX_LIGHTS=16)
|
|
- PBR shader: multi-light loop, point attenuation, spot cone falloff
|
|
- examples/multi_light_demo (orbiting colored point lights)
|
|
|
|
### Phase 4b-2: Shadow Mapping
|
|
- voltex_renderer: ShadowMap (2048x2048 depth), ShadowUniform, ShadowPassUniform
|
|
- Shadow depth-only shader + pipeline (front-face cull, depth bias)
|
|
- PBR shader: shadow map sampling + 3x3 PCF
|
|
- examples/shadow_demo (directional light shadows)
|
|
|
|
### Phase 4c: Normal Map + IBL
|
|
- MeshVertex: tangent[4] added, computed in OBJ parser + sphere generator
|
|
- voltex_renderer: BRDF LUT (CPU Monte Carlo, 256x256), IblResources
|
|
- PBR shader: TBN normal mapping, procedural sky IBL, split-sum approximation
|
|
- Texture bind group: albedo + normal map (pbr_texture_bind_group_layout)
|
|
- IBL merged into shadow bind group (group 3) due to max_bind_groups=4
|
|
- examples/ibl_demo
|
|
|
