Hi,
my goal is to prerender a live camera image with several shader and
display the results of each shader step.
I have a couple of prerender RTT cameras that have textured geometry
quads as children, the shaders are attached to the geometry. The output
texture of a camera is the input texture for the next rendered geometry
quad. All the cameras are attached to the root:
To display the shader result, I created another geometry quad below the
root, with an output texture attached to it.
A View is set to the root with a camera observing the result geometry
quad. That works fine!
But:
I want to display every shader step in a different window. Hence i
created a compositeViewer.
(Since i dont know if cameras can do both RTT and normal rendering i did
the following:)
For each shader output I created an additional geometry quad, textured
with the respective texture and attached to the root via a geode.
However, a View attached to that geode does not show the output texture
of the shader, but the initialised texture value before the shader wrote
to the texture.
How can that be when simultanously the result geometry quad (mentioned
above, with no View attached directly) shows the correct output??
Cheers, Fabian
