Computer Graphics

The nice thing about standards is that there are so many to choose from. (Andrew Tanenbaum)

Because Monday week 10 (Oct 6) is a public holiday there is no lecture. And because half the tutes are on Monday I’m cancelling the tutes on the other days as well. Please use the time to work on assignment 2.

The “graphics standards” topic will not be covered in a lecture, but will be examinable. Read and understand the notes on your own time.

The short we saw this week was Geri’s Game.

Here. On aliasing and animation

(Hill 2nd ed 577-587, 781, 170-172, 91; 3rd ed 487-495, 659, 161-162, 103)

My slides (ODF) Slides in PDF

Chapter 7 of the OpenGL programmer’s guide on Antialiasing (prefiltering using OpenGL).

Chapter 10 of the OpenGL programmer’s guide on The Framebuffer (postfiltering using OpenGL).

Chapter 9 of the OpenGL programmer’s guide on Texture Mapping.

Example OpenGL programs, aargb, accanti and dof are here.

firstAttempt: The famous three dot program from page 46 of Hill.

polyLineDraw: OpenGL and mouse input.

polyTess: OpenGL polygon tesselation.

Toy1: Simplest 3D program - draw the teapot.

Toy2: Calls Starwars to make an X wing fighter.

Toy3: Rotating about x, y and z axes

ToyFinal: Big demo of all the objects list below

StarWars: Use matrix stack to make a Xwing

Function2D: A surface defined by the sinc function.

BezierPatch: One Bezier patch defined by 16 control points.

FractalTree: A simple fractal tree

SurfaceOfRevolution: A surface of revolution

FractalTerrain: Some Fractal Terrain

CSELogo: The Old CSE logo

ShapeManager: A class to manage all the shapes above.

trackball: Uses quaternions to create a virtual trackball. The code is converted from C code in GLUT, so it’s ugly.

Vector3D: 3D vector functions like cross product.

A zip file of everything.

In this lab, we will try one more of Nate Robins’ programs. (more…)

I talked about Global Illumination: link
