# vRayTracer

Simple raytracer in [vlang](https://vlang.io), learning the language as I go along so plenty of poor design choices, some for educational purposes. Based on [Ray Tracing in One Weekend](https://github.com/RayTracing/raytracinginoneweekend).

See f64 branch for more precise but slower implementation using 64 bit floats instead of 32bit.

### Current output

![raytrace output](output.png)

Output is ppm but this is converted with imagemagick `convert output.ppm output.png`

### Building & Running

Compile with `v -o bin/raytrace -prod raytrace.v`

Run with `./raytrace > output.ppm`

### Todo

* Code is a complete and utter mess.

  - Move Ray into module

  - Ray tracer module

* Take scene input from file

* Camera pos/fov

* Focal distance

#### Waiting on vlang for 

* Use Interfaces once working

* Use None instead of error once working

~~* Ensure overloading is used everywhere once working //TODO~~

### Complete

* PPM output

* Fuzz

* Albedo

* Reflection

* Scattering

* Lambertian material

* Metal material

* Dialectric material

* Command line arguments to image size (thanks [spytheman](https://github.com/spytheman).)
