Ray tracer written using C++ with SDL.
In order to compile and run the ray tracer
- Compile with GNU C++ compiler which supports C++17.
- OpenMP must be installed in the default path.
- To run type
make run
Performs ray marching to simulate volumes. The image below shows the result of stacking the sprites in a 2d sprite sheet. The sprites are interpolated between to calculate the density of the volume at a 3d position.
Textures can be projected into primitives using either planar or spherical mapping. The image below shows a Jupiter texture spherically projected onto a sphere primitive.
Noise can also be generated procedurally in either 2D or 3D.
The ray tracer supports ray intersections with triangles, spheres, or rings. Spheres and rings are demonstrated in the image below.
Bending of light due to gravity can be simulated using a gravitational lens shader.
