GoTracer - Volumetric Path Tracing in Go

GoTracer is a Go implimentation of the ray tracer in Ray Tracing in One Weekend.

See /images for example images rendered using the ray tracer.

example.go uses the package pb to display a progress bar but isn't required for the raytracer.

Features / Notes

• Includes multiple surfaces (lambertian, metallic, dielectric, isotropic)
• Includes emissive materials
• Can output in PPM or PNG format
• Supports Spheres, Rectangles, and Boxes
• Supports instance rotation around the Y axis (shouldn't be hard to impliment rotation around X and Z)
• Adjustable depth of field and viewing angle
• Has ambient occlusion, soft shadows, colour bleeding, global illumination
• Anti-Aliasing by taking multiple samples per pixel
• Images are gamma corrected before being saved

Future Additions / Improvements

• Support for cylinders and triangle meshes
• Motion blur
• Procedural textures and image texture mapping
• Importance sampling
• Bidirectional path tracing
• Add parallelism via goroutines
