Sphere Tracer

The following list show the progress I made during the development of the expresion sphere trace.

November, 2001 Solid Noise Added solid noise or 'Hypertexture'.
September 25, 2001 Twist Added CSG operation (union, intersection, difference), soft CSG (blobby objects). Added unary operations Taper and Twist. Also added Axis Aligned Bounding boxes and Fog.
August 8, 2001 Poly Implemented a poly line shape and a poly bezier shape.
August 6, 2001 Shapes Created additional primitive shapes. Currently supported shapes (from left to right, top to bottom): Plane, Sphere, Disk, Torus, Box, Cone, Cylinder.
August 1, 2001 Shades Implemented Tokenizer and Parsing of Shade hierarchy. Currently supported shades (from left to right, top to bottom): FlatShade, Material, Reflective, Texture, Turbulence, ShadeBlend.
Juli 2001 Turbulence Implemented Shade hierarchy, using hard coded scene description. Implemented Light model (Material shade).
Juni 2001 First Initial sphere trace algoritm. Only distance functions and normals are implemented.
