Version 1: Send out rays and return after getting the color of the intersected object. Solid-colored objects will be obtained

Version 2: Add light sources. At this time, the spheres are no longer solid-colored. Add light sources one by one

Version 3: Specular reflection effect

Version 4: Add shadow effect

Version 5: Mirror within mirror effect

Version 6: Change the position and orientation of the camera

Version 1: Draw a straight line based on a linear function

Version 2: Optimize and improve drawing methods

Draw a solid-colored triangle and fill the triangle with horizontally line segments

Draw a gradient-colored triangle. Based on the line segment interpolation, the color is also interpolated

Perspective Projection

A cube made of triangular wireframe

Add a model copy

Transform the model and camera

Clipping: saving computational resources by discarding and splitting triangles

Adding depth testing

Remove faces with their back faces facing us to reduce drawing

Shadowing

Texture Mapping
