Description: This sample illustrates the use of the glColorMask () to inVega Prime to selectively render to only certain color bands of the frame buffer. This sample defines the class myApp, which is derived from vpApp, and overrides the vpApp:: onKeyInput () method to allow for the keyboard input listed below. The sample uses pre/post draw channel subscribers to set the color mask so that the channel can be rendered as monochrome green.
