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 face the user and are also drawn from back to front so that the transparency remains correct.
A deformable bodies simulator based on a standard non-linear strain finite element simulation as in O’Brien et al. [1999]. This approach required incredibly small time steps.
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.
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.
