Rayito is a simple but educational ray tracer written in Go meant as a project to learn programming languages and optimization in Computer Graphics.
"In computer graphics, ray tracing is a technique for generating an image by tracing the path of light through pixels in an image plane and simulating the effects of its encounters with virtual objects." - Wikipedia
Rayito is meant to be simple, but implements a full set of features like:
- Multi Threading
- Oversampling (anti aliasing)
- Ambient and Point Lights
- Custom Materials
- Specular and Difuse shading (Phong)
- Reflection (mirror)
- Refraction (transparency)
- Soft Shadows
- Scene description and parsing
- PNG Export
- and more...
Code is meant to be as clear as possible (no cutting names on variables) so it's meant to be read directly. In order to try Rayito either clone the git repository or do:
go get github.com/phrozen/rayito
After building the binary you can start to render by using some scenes in the samples directory or write your own.
Set workers to the number of threads your CPU can handle (defaults to CPU Max Threads).
