3D Graphics Fundamentals
This cheat sheet covers the essential concepts of 3D graphics, including coordinate systems, transformations, projection, lighting, and shading, crucial for game development.
Core Principles
- Model space defines an object's local coordinate system.
- World space provides a common coordinate system for all objects in a scene.
- View space transforms objects from world space to camera space.
- Projection transforms 3D objects into a 2D view.
- Lighting models simulate how light interacts with surfaces.
- Shading determines how surfaces are colored and rendered.
Quiz
- What is the primary purpose of projection in 3D graphics?: To transform 3D objects into a 2D view
- Which type of light source emits light from a specific point in all directions?: Point light
- What is the main advantage of using triangle meshes in real-time rendering?: They are the simplest polygon type and remain triangles under transformation
