FilterPassSetup
Holds information about the pass that is going to be rendered. Post-processing filters can
modify the frame size or other information about the frame for each pass. This class is used to
keep track of these changes, and pass it along the subsequent passes and filters.

public void setInPlace() Instructs the renderer that the next pass is going to be in-place. An in-place pass does not
redraw the whole frame, but rather overlays something on top of it. The normal rendering
behavior for post-processors is that the result of each pass is given to the next pass, and
the new pass draws on a fresh render target (at least theoretically). By calling this method,
both input and output targets are carried forward from the previous pass, and the output
target will still contain the previous results. In-place filters can greatly improve their
performance by notifying the renderer using this method. |
