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 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.
The terrain was created using the same method as the “Procedurally Generated Terrain” project. The procedural texture is based on a noise algorithm. The trees are a texture-mapped image of a tree onto a rectangle. The alpha channels of the tree are transparent. The trees have billboarding apply so that the tree rectangles turn to […]
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 […]
