interpolation demo, RT004...
Ray-scene intersection basics: planar shapes, convex polyhedron, implicit and algebraic surfaces,
general and rotational quadrics, sphere (geometric solution), torus, surface of revolution,
CSG representation.
Video:
Lecture 4 (2021/22).
Ray-tracer implementation: Solid/Shape revisited (primary computation
vs. additional data = normal vector, TXT coordinates...),

scene objects/nodes as attributes...),
light sources (point/directional).
image synthesis for ray-based rendering – camera, scene, light sources,
computing colors of all pixels in the picture.
Video:

RT004 future:
textures, OOP, scene file-format, acceleration (preprocessing),
parallelism...
Video:
Space dividing methods revisited: grid, 3DDDA, octree, KD-tree, subdivision
approaches, adaptive tree pass.
[Directional acceleration techniques, cube directory, light buffer,
ray coherency, projection plane directory, generalized rays]
Bezier surfaces: Geometric method (Newtonish), De Casteljau subdivision...
Textures in ray-tracing – 2D and 3D textures, table (bitmap) vs. procedural texture,
table interpolations. "Bump-texture" (normal map), stochastic textures - introduction.
Video:
Lecture 6 (2021/22).
More notes on OOP and shadows, recursive ray-tracing (shade()
function). New scene example (120° viewing angle).
