The scene contains a 4-sided room that are light-colored blue. Within this scene are various objects included a texture-mapped sphere and several stacked objects. There are 3 different shadow algorithms being used: projective shadows, shadow volumes, and shadow maps. Projective shadows from objects will only cast shadows on the floor and room, but not on […]

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 […]

The boundaries between the full and half resolution terrain are “stitched” so that no “holes” are visible in the terrain. The user may navigate through the scene […]
