Hello,
I would like to build a HDR example. I have read the following chapter about
HDR:
http://www.learnopengl.com/#!Advanced-Lighting/HDR
and now I try to get exactly that with OpenSG.
If I understand the article correct I do need to render into a floating point
format color target. Here are some questions I have...
How do I get the floating point format render target if I use the HDRStage?
Where does it come from?
How can I setup my own tone mapping shader with the HDRStage?
Do I always have to pay for the shrinking and blurring stuff?
What does the shrinking do at all?
How can I rescue the depth buffer from the original scene rendering into the
display depth buffer?
Sorry for bothering,
best,
Johannes
