Homogeneous Coordinates in Computer Graphics

Homogeneous coordinates are fundamental in computer graphics, facilitating efficient representation and manipulation of geometric transformations. This README outlines their key applications:

1. Representing Transforms as Matrix Multiplications

Homogeneous coordinates simplify the representation of transformations like scaling, rotation, and translation as matrix multiplications, easing integration into graphics pipelines.

2. Translation and Shear Matrices

These coordinates enable the creation of translation and shear matrices, essential for positioning and distorting objects within a graphics scene.

3. Model and View Transforms

Homogeneous coordinates provide an elegant solution for modeling and viewing transformations, ensuring consistency and efficiency in rendering.

4. Projection Matrix

Used for projecting 3D objects onto a 2D screen, projection matrices benefit from homogeneous coordinates, ensuring accurate rendering of scenes.

Applications

Homogeneous coordinates find extensive use in:

  • 3D rendering engines
  • CAD
  • VR/AR systems
  • Animation/VFX production
  • Medical imaging/scientific visualization

Visualization with Manim 3D

Further to understand better , Manim was used to help in visualizing transformations, enhancing understanding and intuition regarding their effects on objects.
