Description

This page is a collection of work illustrative of the course from all the labs throughout the semester.

Lab 1: Image Manipulation and Fractals

The same scene is photographed with (from left to right) just ambient light and then two light sources, one at a time.

The contribution of each light source can be found by subtracting the ambient light from the image with just the single light source. Once isolated, the light source's intensity and color can be modified and then added back to the ambient light image to create synthetic lighting effects.

An example of a Julia set fractal.

Lab 2: 2D graphics Primitives

Using just 2-D graphics primitives, it is possible to create scenes representative of reality.

A bit of physics and some 2-D graphics primitives.

Lab 3: Scan Line Fill

Scan line filling doesn't just have to be solid colors. A pattern, fixed relative to the primitive, can be used as well.

Alpha blending allows for transparent filling.

An OpenGL interface.

Lab 4: Transformations and the 2D Viewing Pipeline

Missile guidance goes bad.

Lab 5: Hierarchical Modeling System

Modules make it easy to create, position, scale, color and rotate primitives like ellipses and circles represented as polygons.

I hate it when I lose the last city in Missile Command...

Lab 6: 3D Viewing Pipeline

Wireframe representation of a Christmas tree.

Lab 7: 3D Hierarchical Modeling

Hierarchical modules allow for relatively easy object duplication and transformation.

Lab 8: Z-Buffer Algorithm

Z-Buffer in action.

Lab 9: Illumination and Shading

Shading adds to the holiday cheer.
