Mathics is a single-threaded CPU rasterizer made as part of CS 334 in Fall 2022 at Purdue University. It is capable of rendering roughly 3,000 triangles at a 1000 × 600 resolution, while achieving about 15 frames per second. This project makes heavy use of C++ modules and other modern C++ features.
- Templated
VectorandMatrixclasses for doing linear algebra. - Collection of over 900 named color constants located in
color.cpp. PinholeCameraclass for projecting and unprojecting points. Supports various forms of manipulating the camera position/rotation.- Reasonably fast rasterization routine with subpixel precision to avoid visual artifacts.
- Screen-space interpolation of vertex colors and normals and model-space interpolation of texture coordinates.
- 2-phase rendering where z-buffering gets done first in order to run the shader code at most once per pixel.
- Back-face culling.
TriangleMeshclass which can either be constructed from a few basic shapes (triangles, quads, etc.) or be loaded from a file.- Cube mapping which supports shadow mapping, reflections, and skyboxes.
- Point and directional light sources (directional light sources don't support shadow mapping).
- Bilinear interpolation for texture lookup and shadow mapping.
- A shader which supports ambient, diffuse, and specular lighting with plenty of customization options.
- A basic material system.
