Hi Robert,
I was trying the luminance component drawing and came across a strange
problem.
1. An osgViewer::View object is added to osgViewer::CompositeViewer.
2. The GraphicsContext is created using createGraphicsContext for given
traits.
3. Used View::GetCamera()->setGraphicsContext
Under the following three conditions, the RTT camera created, actually draws
to the screen and to the texture attached:
1. Texture Internal Format set to GL_LUMINANCE
2. Texture Rendering Camera Viewport set.
I modified the osgDistortion Example to incorporate the above requirements
and was able to reproduce the problem -- Monochrome Scene rendered in specified
viewport and Colored scene rendered at (0,0) with the size equal to the
specified texture size. The moment I make the Texture Internal format GL_RGBA,
everything becomes normal. The same happens if I remove the association of
GraphicsContext with View (removing the createGraphicsContext statement itself).
I don't know if this really is a bug or something wrong in my
understanding. I am really very sorry for troubling you in your busy schedule
every now and then. I really appreciate your sound support. Please bear with
me. Thanks........
Regards
Harash
