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.
The scene is filled with 3D objects featuring ambient and diffuse lighting. The objects cast shadows on each other based on the light using shadow maps. The user may move the light source around.
The scene contains a bump-mapped floor and a bump-mapped swimming fish. The fish is a cylinder which has been warped using a vertex program. The “wriggles” of the fish body are simulated using a sin wave which starts from the fish midline towards the tail. This animation is controlled using an interface which allows the […]
Ray tracer scene containing a sphere and a triangle. Implemented simple phong lighting (ambient, diffuse, specular model) and also casts shadows.
