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.
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 […]
This is a shader implementation of Real-Time Hatching, Praun et al. [2001]. The scene contains a real-time rendering of hatching strokes over various objects. They use tonal art maps containing different stroke sizes and density at various resolutions. Using these tonal art maps, we can render strokes on complex surfaces.
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.
