- Tues: continue to work on Lab 2, part 1.
- Thurs: look at student work for part 1. Begin Lab 2, part 2.
- Look at wave example.
More mathematics
- Matrix representation of transformations: translation, scale, rotation, shear, reflection, projection
- composition
- Rotation/scale around a point other than the origin
- Determinants, inverses
- Homogeneous coordinates
OpenGL
- Matrices in OpenGL
- Modelview Matrix
- Projection Matrix
- Setting matrices: gluLookAt, gluPerspective, glMatrixMode, glLoadIdentity, glPushMatrix, glPopMatrix
- Other OpenGL functions:
- immediate mode: modeling with glBegin/glEnd
- more with transformations glScale, glTranslate, glRotate
- other: enabling depth testing
- storing/specifying geometry: immediate mode (deprecated), display lists(deprecated), vertex lists, vertex buffers.
- Wave program, Algebraic surfaces
Scene Graphs
Recall: OpenGL functions for setting up Transformations
| Modeling transformation modelview matrix | glTranslate, glRotate, glScale |
| Viewing transformation modelview matrix | gluLookAt |
| Projection transformation projection matrix | glFrustum, gluPerspective, glOrtho, gluOrtho2 |
| Viewport transformation | glViewport |
