CS 455 Lecture 4 – Transforms and Indexed Geometry

February 5, 2015 by Chris Johnson. Filed under cs455, lectures, spring 2015.

On a quarter sheet, solve this matrix multiplication problem:
```
| 3 1  2|   |2|
| 2 0  5| * |4|
|-1 3 -2|   |6|
```
More important than the right answer is the mechanics of the multiplication. Show at least some of your work!
With a partner: augment the second renderer to create some rotating non-plane geometric shape of your choosing. Some non-terrible parametrically-defined shapes include a circle, sphere, torus, cylinder, wave, random terrain, and so on. Rotate the object by passing in relevant uniforms to the vertex shader. Send a screenshot of your rotated object before next class.
On your own: start the Gaussian Pox homework. Recall from the syllabus:

Homeworks do not technically have deadlines. However, no more than one homework may be submitted per week, and the first two homeworks must be completed before spring break.
