Rendering

There are two ways to render:

• object-order rendering
• image-order rendering

Ray Tracing is an image-order algorithm.

Steps of Ray Tracing

1. ray generation (Viewing Ray)
2. ray intersection
3. shading

Done

1. Ray-Sphere Intersection
2. Ray-Triangle Intersection

Types of Lights

• Point lights
• Directional lights
• Ambient lights
• Area lights
• Environment lights
