Hi,
I have a scene setup with a texture attached to a camera which is setup
for pre-rendering.
In my scene I set the viewport for the RTT camera to the dimensions of
the texture. Despite having done this, the viewport for the RTT camera
is being inherited from the main scenes camera, i.e. if the viewport of
the main camera is (0,0,8000,600) then only this section of the texture
is rendered, despite the viewport for the rtt camera being
(0,0,1024,1024).
I have stepped through the CullVistor with a debugger and have found
that the viewport does seem to be setup correctly by the cull visitor.
By the time I get to this section of the CullVisitor:
switch(camera.getRenderOrder())
{
case osg::Camera::PRE_RENDER:
//In the following line the viewport for the camera and the rtts is
correct
getCurrentRenderBin()->getStage()->addPreRenderStage(rtts.get(),camera.g
etRenderOrderNum());
break;
default:
getCurrentRenderBin()->getStage()->addPostRenderStage(rtts.get(),camera.
getRenderOrderNum());
break;
}
the viewport seems to have been setup correctly. Both the rtts's
viewport and the cameras viewport is (0,0,1024,1024), but when it is
rendered this is not the viewport that is used.
I am not quite sure where to go from here. Does anyone have any
suggestions on what I may have done wrong or what area I should debug
next?
I am using version 2.9.5 of OSG.
Cheers,
Brad
