Ray Tracing

Robotic Arm

Robotic Arm

This shader is a proof of concept to find out if I could create a “typical” Shadertoy shader, i.e. a shader that renders a non-trivial animated 3D scene, by using a ray tracer instead of the commonly used raymarching techniques.

Ray Tracing – Primitives

Ray Tracing – Primitives

I created a reference shader with ray-primitive intersection routines on Shadertoy. A simple path tracer is used to visualize the scene.

Wolfenstein: Ray Tracing On using WebGL1

Wolfenstein: Ray Tracing On using WebGL1

Since the introduction of the Nvidia RTX graphics cards last summer, ray tracing is back again. In the last months, my Twitter feed got flooded with a continuous stream of RTX On / RTX Off comparisons.

Yet another Cornell Box

Yet another Cornell Box

Yet another Cornell Box: a path tracer in a single fragment shader on Shadertoy. Direct light sampling is used to reduce noise. The scene is rendered using 12 samples per pixel.

Raytracing: the next week

Raytracing: the next week

It’s the next week so time for “Raytracing: the next week” by Peter Shirley. Again, I implemented some of the chapters of the book in four shaders on Shadertoy.

Raytracing in one weekend

Raytracing in one weekend

I know I’m a bit late to the party, but I had a lot of fun reading “Ray tracing in one weekend” by Peter Shirley yesterday. I implemented some of the chapters of the book in four shaders on Shadertoy.

Old watch: a WebGL path tracer

Old watch: a WebGL path tracer

A simple path tracer is used to render an old watch. The old watch scene is (almost) the same scene as rendered using image-based lighting in my Shadertoy shader “Old watch (IBL).”

More spheres

More spheres

Just a repost of one of my first shaders on Shadertoy. This is a simple realtime path tracer, implemented in a WebGL fragment shader. The shader shows motion blur, depth of field and importance sampling.
