Hi,
did you calculate a world volume?
DynamicVolume vol;
node->getWorldVolume(vol);

Hi all,
I wanted to do some very basic collision detection/volume intersection test, like in
"return(vol1.intersect(vol2)) ...". This line worked fine as long as one of the
nodes providing the volumes was directly manipulated by changing it's matrix (given a
transform or componentTransform core). For example I used this code in a test application
where drops were falling to the ground. A drop was represented by a node with
componentTransform core that had a node with geometry core as a child. Everything worked
fine.
In an other test application I used nodes with componentTransform core to
simulate joint behavior. In this application a joint was built like this:

I wanted to check whether the child shown in the image collided with a box but it didn't work, my code line never returned "true" though I could see there was a collision.
While debugging I noticed that the matrix of the child never changed which somewhat made sense since (as far as I understood it) it only represents a transformation of the coordinate system of the parent to the position of the child and was never directly manipulated. Still I think this could be the reason for the intersect() function not working properly.
At the moment I have no idea how I can get it to work, if someone could help me
out I'd be really grateful :-)
regards
Christoph
