I created a reference shader with ray-primitive intersection routines on Shadertoy. A simple path tracer is used to visualize the scene.
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.
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.
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)“.
“Human Document” – my entry for the Shadertoy Competition 2018. A bit to my surprise, this shader turned out to be the winning entry :) You can find (the full source of) the fragment shader here: https://www.shadertoy.com/view/XtcyW4.
This shader uses Image-Based Lighting to render an old watch. The materials of the objects in the scene have physically-based properties.
