We definitely lost one of our nine lives this week with integrating face tracking into our game, but we still have our cat’s eyes, and are still feel very confident that we will be able to show a stellar game at GDC. On the face tracking end of things we had some big wins. We are finally happy with the speed of the algorithms, and the way things are being tracked will work perfectly for putting into Kiwi Catapult Revenge. We completed some complex math to create very realistic perspective shiting in Unity.

Most of this week  have been used to work on the Interface library you can see a demo of here:

This sample demonstrates how trimming particle quads down in size can increase performance by decreasing the amount of unnecessary texture sampling. This technique has been around for a while, but still isn’t very prevalent. The basis for this sample is a particle trimming tool created by Emil Persson, described in detail on his blog here.
