Hi,
I am new on all this stuff. So, I apologize if my questions are so simple.
I am working in visual studio 2008 and OSG. In my scene, I load some .obj files
and I want to detect collision between them. I want to retrieve the vertices of
my .obj geometry to star working with them. does anybody know how can I do
this? or have an advice?
If you use osgBullet.googlecode.com, you can convert your scene graph directly
to a Bullet collision shape and use Bullet to perform collision detection. In
this case, you wouldn't need to access the vertices directly.
Even if you don't want to use Bullet for collision detection, the osgBullet
project contains the CollectVerticesVisitor, which collects a set of transformed
vertices from a scene graph. You might find this code useful.
