<H2 >Vega Channel (vgChannel)</H2>
The Vega Channel functions (vgChannel) describe a view into a scene and a rectangular region of a window where the view will be displayed. A single window may have several channels associated with it, but the channel may only be associated with one window. The channels are drawn in the order in which they were defined. Channels cannot be destroyed once created, but they can be disabled and enabled. A channel is a visual channel to render the scene. The API here will let you control how the scene is projected on the screen in terms of environment, how the screen is cleared the shape and size of the viewports … you’ll see as we go through each and every painless line of code.
