A sample library of simple Shake plugins I've written can be downloaded below. It contains the following:
|HSVKey||hue based difference keyer for tricky difference keying|
|Chirp||Chirp chart generator for analysis of effects, cameras and monitors|
|Tubify||projects images onto a 3D tunnel|
|Polka||draws circles, squares or dots with sub-pixel precision|
|Stripe||draws horizontal or vertical stripes for checking image alignment and distortion|
|GaussNoise||Adds random gaussian noise to an image to give it texture or to simulate low quality and night vision cameras|
These plugins are free to use - feel free to pass them on to other people. You can modify them if you need to. However, you may not distribute modified versions without permission (unlike software released under the GPL) - I wrote these plugins to demonstrate my skills at writing them, not your skills at modifying them ;-)
I'm really in the business of writing custom shake plugins and macros - get in touch with me (firstname.lastname@example.org) to discuss what you might need.
These plugins are very simple, taking a few hours each to write, and don't really rely on complex image processing or computer graphics techniques. They are not the limit of what I can with Shake plugins!
