What this skill does
3D Game Development Principles for 3D game systems. --- 1. Rendering Pipeline Stages Optimization Principles Technique Purpose ----------- --------- Frustum culling Don't render off-screen Occlusion culling Don't render hidden LOD Less detail at distance Batching Combine draw calls --- 2. Shader Principles Shader Types Type Purpose ------ --------- Vertex Position, normals Fragment/Pixel Color, lighting Compute General computation When to Write Custom Shaders Special effects (water, fire, portals) Stylized rendering (toon, sketch) Performance optimization Unique visual identity --- 3. 3D Physics Collision Shapes Shape Use Case ------- ---------- Box Buildings, crates Sphere Balls, quick checks Capsule Characters Mesh Terrain (expensive) Principles Simple colliders, complex visuals Layer-based filtering Raycasting for line-of-sight --- 4. Camera Systems Camera Types Type Use ------ ----- Third-person Action, adventure First-person Immersive, FPS Isometric Strategy, RPG Orbital Inspection, editors Camera Feel Smooth following (lerp) Collision avoidance Look-ahead for movement FOV changes for speed --- 5. Lighting Light Types Type Use ------ ----- Directional Sun, moon Point Lamps, torches Spot Flashlight, stage Ambient Base illumination Performance Consideration Real-time shadows are expensive Bake when possible Shadow cascades for large worlds --- 6. Level of Detail (LOD) LOD Strategy Distance Model ---------- ------- Near Full detail Medium 50% triangles Far 25% or billboard --- 7. Anti-Patterns ❌ Don't ✅ Do ---------- ------- Mesh colliders everywhere Simple shapes Real-time shadows on mobile Baked or blob shadows One LOD for all distances Distance-based LOD Unoptimized shaders Profile and simplify --- Remember: 3D is about illusion. Create the impression of detail, not the detail itself.
