2D Contouring and Color Maps

The purpose of this project was to visualize how Mount St. Helens was changed by the eruption of 5/18/80. I used Historic Digital Elevation Models (DEM) from the United States Geological Survey website. The terrains have a color map to show the elevations and also has 2D contours at proper elevations to highlight distinct heights. The terrains were drawn side by side for comparison purposes.

Texture Mapping

Texture mapped a 4-sided room such that one wall has front-side culling applied. The floor is texture mapped using a checkerboard image and also feature mip mapping. The walls of the room are a repeated brick texture. There is a floating sphere in the center of the room texture mapped with the image of the […]

Procedurally Generated Terrain

The ground is procedurally generated using a random midpoint method and smoothed using a neighborhood smoothing filter. The trees were generated by different procedural rules. The scene uses OpenGL material and lighting.

Phong Shading, Garoud Shading

The scene is a 4-sided room containing a polished gold metallic sphere, polished copper metallic teapot, and polished silver metallic torus. I created an interface control which allows switching between vertex Gouraud shading and per-pixel Phong shading.
