A Haskell ray tracer largely based on http://www.raytracegroundup.com/

tracy - a Haskell ray tracer

Features:

• Basic idealized primitives: triangles, spheres, concave spheres, boxes, planes, tori, rectangles, triangle meshes
• Mesh shading modes: flat, smooth (when vertex normals are available), textured (when UV coordinates are available)
• Mesh file formats: PLY
• Acceleration aids: regular grids, bounding volume hierarchies
• Materials and shading: phong, matte, perfect specular reflection, glossy specular reflection, blended materials
• Image-based textures
• Procedural textures: planar checkers, spherical checkers
• Texture mappings: rectangular, tiled (planar), spherical
• Object instancing
• Object transformations
• Samplers: regular, random, jittered, multi-jittered, correlated multi-jittered
• Global illumation: ambient occlusion, path-tracing
• Cameras: thin-lens
• Light source types: ambient, point, area (rectangles only), environment
• Console output with status information
• Live GUI window with progressive rendering
• YAML-based scene file format
• Basic animation support for some scalar and vector parameters
• Movie output when rendering more than one frame
• Multi-core rendering engine using Haskell's parMap evaluation strategy
• Network rendering (run tracy -d tcp://slave:9000 on the master, tracy-node on the slave(s))
