The accounts for CS 494/594 are ready for pickup in Claxton 106
Textbook: Fundamentals of Computer Graphics, 3rd Ed. (P Shirley et al)

This course is concerned with algorithms for creating
2D images of objects in 3-dimensional space.
To make objects that look real, one simulates the way light
is emitted and then reflects from objects.
The result is sampled and reconstructed on a rectangular
grid of color pixels.
Students who took this course have gone to work at
film studios (Pixar, Rhythm and Hues), game companies
(ESPN Games, Naughty Dog, Infinite Games),
research labs (NASA, Army CEWES, ORNL, Lockheed-Martin),
and technology companies (Apple, Intel, Nvidia, Microsoft).

This course is about how to develop good software for
computer graphics. But it is fun
to experiment with writing really incomprehensible
code.
Here's a graphics program
I wrote to show that 4 lines
of C-code
can transform,
illuminate, and z-buffer a torus.
Save this code as as torus.c,
then type (in a UNIX shell) cc torus.c -o torus -lm.
Run it in a terminal window.
char G[]="^<VL8CO! ",C[80][80],*P,k,j;double sin(),cos(),c,x,z,L,M,N,i,I=.01;
main(){for(;i<629;){N=sin(i*I);c=cos(i*I);M=sin(i);L=cos(i+=I);x=c+3;z=3*M*x+
60-N;if(z>*(P=&C[k=z+5*N][j=40+x*L*9])){*P=z;c*=L+M-N/c;P[-3200]=G[k=c<0?0:
c*5];}}for(P=*C;P<=C[40];)putchar((P++-*C)%80?*P+32:10);}
It was submitted to the
Obfuscated C
Contest.
