Hello,
I use osg:: LineSegment to perform an intersection between a ray starting from
a wand and the objects in my scene. Here is my code:
osg::Vec3 wandpt1;
osg::Vec3 wandpt2;
line = new osg::LineSegment(wandpt1,wandpt2);
osg::BoundingBox modelbox;
modelbox.expandBy(modelTransf->getBound());
if(line->intersect(modelbox)){
std::cout << "intersection with the cow" << std::endl;
}
The problem is that detection is not very precise.
Do you know another solution in openscenegraph for this?
Thank you!
