Hi,
I want to mix some FBO pre-render cameras and osgCuda. Basically I need
to do the following in a single frame:
- do some FBO rendering
- some cuda ops
- again some FBO rendering
- some cuda ops
- again some FBO rendering
For each "cuda ops" part I have a Computation node. Ideally I'd like to
let the order be determined just by the order I've attached the nodes to
a common parent node (this works for pre-render FBO cameras), but
Computation creates render bins and no matter in what order I attach
things (I've tried Computation with and without children) the order of
my operations is wrong.
Because I'm doing FBO rendering I want the cuda ops to be done in the
render traversal too, i.e. I cannot do it in update traversal.
Is there a way I can let Computation happen in the render traversal, but
without it changing bins?
I "fixed" it by placing the Computation node under a dummy FBO camera.
Now all computation happens in pre-render stage and in right order.

thanks
