Functional distributed ray tracer for computer graphics
- Phong illumination
- Intersection with sphere
- Intersection with plane
- Single ray casting
- Recursive ray tracing
Achieved by adding a 'depth' parameter when shooting rays. Recursively reflects rays in a slightly random direction until depth=0. - Anti-aliasing
Achieved by shooting more rays per pixel and averaging the colors. - Depth of field
Achieved by shading each pixel with more rays that starts at random places on lens and points to the focal point. - Extended light source, soft shadow
Achieved by approximating point lights as spheres and using a random point on the sphere as the light's position during intersections. - Texture mapping
Achieved by adding Texture class to Material and converting 3D intersection points to UV space to map to the 2D texture maps. - Reflection
Achieved by shooting another ray in the perfect specular direction given the normal and incoming ray direction. - Refraction
Achieved by applying snell's law. - Fresnel law
Balanced between refraction and reflection color using fresnel law. - Glossy effect
Achieved by distorting the direction of the reflected ray to take into account the roughness of the surface. - Non-trivial object
Added support for rendering cylinder objects.
