Math for Computer Graphics and Computer Vision
Not surprisingly, the mathematics used in computer graphics was touched upon by the students at Drexel and Swarthmore during the summer of '09. Some of the Helper Pages, in particular are needed topics for some of the image pages, and for computer graphics.
As students turned their creative talents on these topics we decided to open this repository of software devoted to understanding them. Our hope is that it will develop into a useful resource for students and faculty in both disciplines. Please contribute your good material!
The following is a list of mathematical topics used in computer graphics. The original list was provided by Drexel professor David Breen.
- 2D, 3D, 4D real spaces; affine subspaces; homogeneous coordinates
- Vectors and Matrices
- Graphics primitives
- 2D primitives developed from triangles: fans, strips
- Convexity and convex sums
- 3D models based on 2D faces
- Do we save machine representations for the CG course?
- Primitive geometric transformations
- Creating general transformations via sequences of primitives
- Inverse transformations via primitives
- Do we include transformation stacks?
- This might well be phrased in terms of the viewing transformation
- Hierarchical coordinate systems
- Implicit geometry - lines, circles, ellipses
- Implicit Surfaces - quadrics, superquadrics
- Implicit Equations
- Parametric geometry - lines, circles, ellipses
- Curves (Catmull-Rom, Bezier, B-spline)
- Parametric surfaces - quadrics, superquadrics, others
- Bezier patches
- Subdivision surfaces
- Procedural Image
- Surface normals
- Techniques of computing them from analytic and non-analytic cases
- Silhouette Edges
- Procedural texture maps
- Ray-object intersection
- Bounding spheres and boxes?
- Perspective and parallel planar projections
- Non-planar projections
- Edge detection
- Fourier analysis and convolution
More examples may be found in the lecture slides of CS 430.
