Hum... there's still a problem...
how can I retrieve intersected vertices from polytope intersection ?
>From a LineSegmentIntersector, I use this code :
Code:
intersection is a osgUtil::LineSegmentIntersector::Intersection instance from
LineSegmentIntersector
osg::Geometry* pGeometry =
dynamic_cast<osg::Geometry*>(intersection.drawable.get());
if (pGeometry != NULL)
{
osg::ref_ptr<osg::Vec3Array> pVertexArray =
dynamic_cast<osg::Vec3Array*>(pGeometry->getVertexArray());
if (pVertexArray != NULL)
{
for (unsigned int i=0; i<intersection.indexList.size(); i++)
{
if ( (nearestVertexIndex >= 0) && (nearestVertexIndex <
(int) pVertexArray->size()) )
{
addVertexToSelection(pGeometry,
nearestVertexIndex);
}
}
}
}
