		float &	imageX,
		float &	imageY
	)

Here is the caller graph for this function:

void MWRender::GlobalMap::cleanupCameras

(

)

Removes cameras that have already been rendered. Should be called every frame to ensure that we do not render the same map more than once. Note, this cleanup is difficult to implement in an automated fashion, since we can't alter the scene graph structure from within an update callback.

Here is the call graph for this function:

Here is the caller graph for this function:

void MWRender::GlobalMap::clear

(

)

Clears the overlay.

private

Request rendering a 2d quad onto mOverlayTexture. x, y, width and height are the destination coordinates (top-left coordinate origin)

Parameters

cpuCopy

copy the resulting render onto mOverlayImage as well?
