# Math for Computer Graphics and Computer Vision

### From Math Images

The Drexel group may also want to focus on the math used in computer graphics and computer vision. Here are some examples.

- Vectors and matrices
- Transformations
- Quaternions
- Hierarchical coordinate systems
- Geometry

- Curves (Catmull-Rom, Bezier, B-spline)
- Bezier patches
- Subdivision surfaces
- Implicit geometry - lines, circles, ellipses
- Implicit surfaces - quadrics, superquadrics

- Surface normals
- Silhouette edges
- Procedural texture maps
- Ray-object intersection
- Perspective and parallel projection
- Edge detection
- Fourier analysis and convolution

More examples may be found in the lecture slides of CS 430.
