A 3D rendering pipeline should be structured across vertex processing, rasterization, fragment processing, and output stages. You can optimize this pipeline using frustum culling, occlusion culling, LOD, and batching strategies to reduce draw calls.

Author custom shaders when you need specific visual effects, improved performance, or a unique visual identity. You can implement vertex, fragment, or compute shaders depending on whether you are transforming geometry, coloring pixels, or executing general-purpose GPU computations.

The best way to implement 3D physics collisions is by matching collision shapes to your objects using boxes, spheres, capsules, or meshes. You should apply fundamental collision principles, filtering, and raycasting to handle interactions accurately.

Set up a 3D camera system by choosing between third-person, first-person, isometric, or orbital camera types. Implement smooth motion, collision avoidance, and look-ahead techniques to ensure the camera navigates the environment without clipping through geometry.

3D game lighting often requires baking strategies for performance optimization when using directional, point, spot, and ambient lights. Baking pre-calculates lighting to reduce runtime rendering costs, balancing visual quality with real-time performance constraints.

Common anti-patterns in 3D game systems include inefficient rendering pipelines, poor LOD planning across near and far distances, and improper collision shape selection. Following established best practices helps avoid these structural pitfalls and ensures scalable game architecture.
