The latest addition on my journey to OSL is a WindowBox (sometimes also called Interior Mapping or Parallax Mapping) shader.

I remember one of our teachers in university telling us about how they rendered all the interiors of the buildings in Spiderman with just a simple plane with a shader attached to it that simulates the room interior with proper parallax. Since then this has always stuck in my mind and I saw it being used in some studios I worked at whenever there was a big city to be rendered. I finally found the time (.. too much time :) ) to do this sort of shader myself in OSL!

I had another go at playing around with OSL. This time I tried making a Tri Planar (or sometimes also called Round Cube or Blended Box Mapping) shader. It was an interesting thing to try out as it involves a bit more work. What I came up with however merely serves as an experimental try-out rather than being useful for production. It has a few common features that you would most likely find in modern rendering or texturing packages.

Iridescence on surfaces is an interesting effect and can be a challenge to get looking correctly. This effect occurs for example on some animal skin as well as on surfaces covered in oil under certain conditions. Because it is a very specific look it can often times require lots of iterations until the client is happy with the result, so quick turnarounds are often neccessery. Luckily it also often times is quite a subtle effect so it’s a good candidate to try and look develop in 2D instead of constantly re-rendering your CG.
