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.
A particle system that uses an attractor force that pulls particles to a respective position in space. These positions were based on vertex positions from an obj file.
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 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.
