Graphics Pipeline#

Implementation of a 2D/3D graphics transformation pipline with the following features:

• A matrix stack containing transformation matrices: Model, Camera, Projection, and Viewport
• Functions to manipulate the matrix stack
• Functions to apply transformations to the matrix stack
• A basic 2D scene constructed using custom transformation functions
• A basic animated 3D scene that extrapolates the previous 2D implementation of the graphics pipeline to 3D

The following controls are used when running the code:

• [: Rotate Clockwise
• ]: Rotate Counter-Clockwise
• =: Zoom in
• -: Zoom out
• O: Switch between the following orthographic projection modes
  • Indentity: Projection, Camera and Model matrices are all identity
  • Center600: Centered on (0,0) with the side boundaries in the range [-300,300]
  • TopRight600: Bottom left is (0,0), top right is (600,600)
  • FlipX: Same as Center600, but flipped through the Y-Axis
  • Aspect: Uneven aspect ratio, X-Range is (-300,300), Y-Range is (-100,100)
• D: Switch between the following display modes
  • Pattern: A multicolored grid pattern
  • Scene: A basic drawing made using the custom graphics pipeline and functions for rotation, translation, etc.
  • Shapes: An animated 3D scene featuring squares moving away from the camera utilizing orthographic projection.
