What is it?

Sharptrace is a ray tracing program, written in C#. It has the following features: Floating point (32-bit per color component) raytracer with 24bpp PNG files output, written in C# Multithreaded rendering core for better speed on multi-core machines. It's still horribly slow though, thanks to the awesome power of C# Reflections Transparency with optional refraction Fog Anti-aliasing Depth-of-field blurring XML scene format User Interface with preview window and auto-resume of partial renders OpenGL based scanline renderer for fast scene setup preview Renders spheres, triangle meshes (.3ds binary and .ply format) Per-mesh Octrees Multiple colored point/spherical area lights, casting hard/soft shadows, using a direct lighting model with ambient, diffuse and phong components Full HDR pipeline, with post-processing bloom if desired Sky light (~ambient occlusion) Texture mapping supported (but optional) on all primitives, using bilinear filtering if so desired Procedural texture mapping supported on all primitives (currently checkerboard only) Skydomes And here's the gallery of some hi-res, hi-quality pictures that show off most of the features of the raytracer in nice settings
