Hi,
using the example, osgparticleeffects.cpp, I added the following lines of code
to the pick function (inside the //MGREENE section):
Code:
void pick(osgViewer::Viewer* viewer, const osgGA::GUIEventAdapter& ea)
{
osg::Group* root = dynamic_cast<osg::Group*>(viewer->getSceneData());
if (!root) return;
osgUtil::LineSegmentIntersector::Intersections intersections;
if (viewer->computeIntersections(ea,intersections))
{
const osgUtil::LineSegmentIntersector::Intersection& hit =
*intersections.begin();
//MGREENE
std::cout << "hit = " <<
hit.getWorldIntersectPoint().x() << "," << hit.getWorldIntersectPoint().y() <<
"," << hit.getWorldIntersectPoint().z() << std::endl;
osg::Vec3 tc(0,0,0);
osg::ref_ptr<osg::Texture> myTexture =
hit.getTextureLookUp(tc);
std::cout << "tc = " << tc.x() << "," << tc.y() << ","
<< tc.z()<< std::endl;
//END MGREENE
bool handleMovingModels = false;
...
but the values of tc are always 0,0,0.
Thank you!
Cheers,
Mike[/code]
