I'm not sure what you're talking about. ShaderToy.jl just makes it easy to execute an OpenGL shader written in GLSL, which then runs directly on the GPU. Running an OpenGL shader, animating some variables and displaying the results requires some setup, which is the part done in Julia.
Ray tracing just happens to be a much applied technology on shadertoy.com, which is why the examples I copied use ray tracing. If you go to shadertoy.com, you will see a lot of other stuff. There are worlds between these simple toy ray tracing implementation and IRay from nvidia. It's not comparable at all. Am Donnerstag, 24.
