7	## 1. Rendering Pipeline
8
9	### Stages
10
11	```
12	1. Vertex Processing → Transform geometry
13	2. Rasterization → Convert to pixels
14	3. Fragment Processing → Color pixels
15	4. Output → To screen
16	```
17
18	### Optimization Principles
19
20	\| Technique \| Purpose \|
21	\|-----------\|---------\|
22	\| Frustum culling \| Don't render off-screen \|
23	\| Occlusion culling \| Don't render hidden \|
24	\| LOD \| Less detail at distance \|
25	\| Batching \| Combine draw calls \|
26
27	---
28
29	## 2. Shader Principles
30
31	### Shader Types
32
33	\| Type \| Purpose \|
34	\|------\|---------\|
35	\| Vertex \| Position, normals \|
36	\| Fragment/Pixel \| Color, lighting \|
37	\| Compute \| General computation \|
38
39	### When to Write Custom Shaders
40
41	- Special effects (water, fire, portals)
42	- Stylized rendering (toon, sketch)
43	- Performance optimization
44	- Unique visual identity
45
46	---
47
48	## 3. 3D Physics
49
50	### Collision Shapes
51
52	\| Shape \| Use Case \|
53	\|-------\|----------\|
54	\| Box \| Buildings, crates \|
55	\| Sphere \| Balls, quick checks \|
56	\| Capsule \| Characters \|
57	\| Mesh \| Terrain (expensive) \|
58
59	### Principles
60
61	- Simple colliders, complex visuals
62	- Layer-based filtering
63	- Raycasting for line-of-sight
64
65	---
66
67	## 4. Camera Systems
68
69	### Camera Types
70
71	\| Type \| Use \|
72	\|------\|-----\|
73	\| Third-person \| Action, adventure \|
74	\| First-person \| Immersive, FPS \|
75	\| Isometric \| Strategy, RPG \|
76	\| Orbital \| Inspection, editors \|
77
78	### Camera Feel
79
80	- Smooth following (lerp)
81	- Collision avoidance
82	- Look-ahead for movement
83	- FOV changes for speed
84
85	---
86
87	## 5. Lighting
88
89	### Light Types
90
91	\| Type \| Use \|
92	\|------\|-----\|
93	\| Directional \| Sun, moon \|
94	\| Point \| Lamps, torches \|
95	\| Spot \| Flashlight, stage \|
96	\| Ambient \| Base illumination \|
97
98	### Performance Consideration
99
100	- Real-time shadows are expensive
101	- Bake when possible
102	- Shadow cascades for large worlds
103
104	---
105
106	## 6. Level of Detail (LOD)
107
108	### LOD Strategy
109
110	\| Distance \| Model \|
111	\|----------\|-------\|
112	\| Near \| Full detail \|
113	\| Medium \| 50% triangles \|
114	\| Far \| 25% or billboard \|
115
116	---
117
118	## 7. Anti-Patterns
119
120	\| ❌ Don't \| ✅ Do \|
121	\|----------\|-------\|
122	\| Mesh colliders everywhere \| Simple shapes \|
123	\| Real-time shadows on mobile \| Baked or blob shadows \|
124	\| One LOD for all distances \| Distance-based LOD \|
125	\| Unoptimized shaders \| Profile and simplify \|
126
127	---
128
129	> Remember: 3D is about illusion. Create the impression of detail, not the detail itself.
