Raytracer
C++ project to render scenes from json specifications
This Raytracer program, written in C++, supports:
- Full Phong Lighting Model
- shadows
- reflections
- textures
- super sampling
- Cel-shader (a.k.a. Toon-shader)
- Gooch shader
The objects supported are:
- sphere
- triangle
- quad
- plane
- cylinder (with caps)
- triangle meshes
Some examples of rendered scenes. On the left, some sphere rendered with the Phong lighting model. In the middle, the same scene is rendered with the Toon-shader. On the right right, a sphere is rendered with a texture.
The scenes to be rendered are read from a .json file, which contains the details of each model to be rendered. Using some additional scripts, it’s possible to render more complex scenes. For example, below there is a render of a DNA helix, with some H2O molecules floating around in random positions.
A scene showing a DNA helix and H2O molecules.
The script also supports non-photorealistic shading, which are toon-shading and cell-shading, as shown in some example images below.
