Renderer is a command-line, open source application which allows interactive 3D visualization of triangle meshes.
The renderer allows switching between rasterizing and raytracing in real-time – so one navigates quickly with the rasterizers, and requests a raytracing when the viewpoint is interesting.
The software is released under an open source license.
Key Features
- 3D transformations (from world coordinates, to camera-space/light-space coordinates).
- Point rendering (vertex-based or triangle-based).
- Anti-aliased lines rendering.
- Gouraud shading (complete Phong equation calculated per vertex).
- Phong shading (complete Phong equation calculated per pixel).
- Z-Buffer hidden surface removal.
- Shadow mapping.
- Soft shadow mapping.
- Raytracing, with shadows, reflections, refractions, ambient occlusion and anti-aliasing.
- Portable display and keyboard handling through libSDL.
- Supported 3D formats: .3ds, .tri, and .ply.
