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.

Isosurface Computation and Display

The purpose for this project was to visualize interactively isosurfaces of a 3D dataset for three levels of resolution. Using the provided datasets, I extracted and rendered an isosurface. I also added two user interface components that allow a user to change the isovalue of the isosurface and level of resolution of the dataset.

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.
