Bret Victor / worrydream.com

I spent about an hour tracking Bret down again today. I remembered reading his article The Ladder of Abstraction and being really engrossed by it, but couldn’t remember what it was called or who wrote it. Bret’s talks, explorations, articles and designs are really great. I highly recommend you peruse his site and follow him on Twitter!

Per-Pixel Anisotropic Direction

When dealing with anisotropic lighting models you often need to define the anisotropic direction. Usually it’s easiest to author your content to conform to some constant direction, like +U or -V in UV space. However, this is not always possible. This example shows how the anisotropic direction can be calculated radiating outwards from a specific point in UV space (the center, in this case). Obviously this is a simple case, but it illustrates a way to define your anisotropic direction on a per-pixel basis. Another way to do this is by painting a gradient along the direction of flow...

iOS App Icon Template

I came across this today when designing an icon for my iOS app. I thought "someone has to have made this easy." Sure enough, they did.

Using Eclipse with Maya: A Quick Reference

If you’re doing tools work in Maya and you aren’t using Python, PyQt, and an IDE for debugging… well… quite frankly you’re doing it wrong. 🙂 There are a few guides out there that have helped me and others get this workflow going, such as this one from Nathan Horne and this one from Christian Akesson. You should definitely read both of those posts, because almost everything I learned about this topic came from these two guys. The purpose of this post is to shortcut the process to get this up and running as fast as possible using Maya 2012 x64, without delving...

Spherical Environment Mapping

Sometimes it can be useful to have the sky to appear at infinity even though the geometry is really close, or perhaps you want to seamlessly blend near and far 3D elements with the skydome in the material regardless of position. Examples to...

Useful Tools

I came across a few tools recently that are proving to be quite useful in my workflow. Not only are they free, but they actually work pretty well! Handbrake – An open source media encoder that’s great at mp4, the new web standard. Also has easy presets for iOS devices and a host of other targets. I found the UI to be simple and intuitive, and to produce better, faster, and easier results than Apple’s Quicktime Pro. CamStudio – I like Camtasia Sudio but the price tag is a bit much for me. CamStudio is a great free alternative that makes creating tutorials and screen...
