Hi Sergey,
Hi, Sebastian
you can get (already computed by cullvisitor) modelview matrix in cull
callback. But i think you are overcomplicating things with this approach.
Okay, I hadn't thought of this. So you propose adding a cull-callback to
all the nodes that should contribute?
And surely I felt that the approach was too complicated, thats why I was
asking ;-)
cheers
Sebastian
Cheers,
Sergey.

Hello,
I'm trying to implement per object motion blur in my deferred pipeline.
In order to get this right, I need the modelview matrix from the
previous frame per node.
To get it I was thinking about using an updateCallback per node that
should contribute to the motion blur. Unfortunately I think this will
get too expensive, as I have to compute the local to world per call.
Also is the updateCallback called if the camera moves? If not I have to
install an callback that is called per frame ..
Any suggestions how to get the last frames modelview matrix?
cheers
Sebastian
