GFXTarget
Base class for a target to which GFX can render.
Private Attributes
Protected Functions
Called whenever a change is made to this target.
Called when the device has applied pending state.
Public Functions
Constructor to initialize the state tracking logic.
This is called when the target is not being used anymore.
The resource should put a description of itself (number of vertices, size/width of texture, etc.) in buffer.
const bool
Called to check if we have pending state for the device to apply.
preserve()
This tells the target that the contents of this target should be restored when activate() is next called.
resolveTo(GFXTextureObject * tex)
Copy this surface to the passed GFXTextureObject.
Detailed Description
Base class for a target to which GFX can render.
Most modern graphics hardware supports selecting render targets. However, there may be multiple types of render target, with wildly varying device-level implementations, resource requirements, and so forth.
This base class is used to represent a render target; it might be a context tied to a window, or a set of surfaces or textures.
