# zraytrace
Ray tracing implemented in [Zig](https://ziglang.org/).
## Inspiration
Code follows mostly [Ray Tracing in One Weekend](https://raytracing.github.io/) and [Physically Based Rendering](http://www.pbr-book.org/).
## Features
Single threaded, uses only on CPU.
Materials:
- diffuse (matte)
- metal (fully reflective)
- dielectric (glass like objects)
Shapes
- sphere
- triangle
Textures:
- constant color
- image textures
Algorithms
- Bounded volume hierarchy
File formats:
- PNG images, read and write
- OBJ 3d models, read
# Examples
## Spheres
This doesn't use bounded volume hierarchy because its overhead is too big for scene with 7 spheres.
From the left:
- reflective texture mapped sphere (earth)
- hollow dielectric sphere (glass)
- diffuse texture mapped sphere (Nitor logo)
- filled dielectric sphere (glass)
- reflective sphere with silver color (mirror ball)
- diffuse green sphere (ground level)
