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.
3D terrain visualization program which loads a terrain map file containing unsigned chars. The terrain switches to a half resolution version based on the distance from the viewer. 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 […]
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.
Ray tracer scene containing a sphere and a triangle. Implemented simple phong lighting (ambient, diffuse, specular model) and also casts shadows.
