Ray Tracer Project

I have written a ray tracer as a course project (for a senior graphics course at the University of Waterloo). Below are images highlighting the features implemented.

Antialiasing

No antialiasing.

Flagged pixels.

Antialiased

Soft Shadows

No soft shadows

Soft shadows (81 rpp).

Phong Shading

No phong

Phong

Constructive Solid Geometry (CSG)

Additional primitives

CSG

Another scene involving CSG

Texture Mapped Primitives

Textured primitives

Textured mesh (not using texture coordinates)

Texture Mapped Meshes

Textured primitives

Texture map

Textured mesh (using texture coordinates)

Refraction

Objects in refractive materials

Refractive mesh

Caustics

'Cowstics?' --Will

Photon map

Depth of Field (DOF)

DOF - Focused on middle pot

DOF - Focused on near pot

Octrees
