Package rosequartz.gfx

Class GraphicsState

java.lang.Object
rosequartz.gfx.GraphicsState
public class GraphicsState extends Object
Represents a State in the Graphics Pipeline. This class can be used to get a copy of the current state of the graphics pipeline, with the current render target, the selected shader program, depth testing settings and more. The state can then be changed and restored. This makes it easy for making APIs where the state needs to be exactly like before, or managing the state in general. This class stores: 

 - selected depth testing function
 - depth testing enabled / disabled
 - targeted render target
 - selected shader program
