# 3D Rendering Pipeline in MATLAB

### Features

- Perspective or Orthographic projection (Right Handed Axis)

- Full object transform (Scale, Rotation, Translation)

- Freely position camera in 3D space

- Configurable camera FOV and aspect ratio

- Any number of point lights, with any color

- Per vertex shading with Specular & Diffuse lighting passes (ambient optional)

- Only 30 lines of code! Fully vectorized, no loops used
