Hi everyone,
The setProjectionMatrixAsOrtho2D-function is not really clear to me.
I have tried a lot of different variables to give to this funtion.
But they all result in a sceen with a blue background. Not even a small part of
the object I am trying to see.
What I have is a 3D-model (like cow.osg of cessna.osg) and I want a side view
in Ortho 2D.
Can anyone help me with calculating suitable values?
I found and tried the example below, but no luck... :(
Code:
osg::ref_ptr<osg::Node> node;
Viewer->setSceneData(node);
osg::BoundingBox bb;
bb.expandBy(node->getBound());
double xMid = (bb.xMin() + bb.xMax())/2;
double yMid = (bb.yMin() + bb.yMax())/2;
double zMid = (bb.zMin() + bb.zMax())/2;
double radius = bb.radius();
Viewer->getCamera()->setComputeNearFarMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR);
Viewer->getCamera()->setProjectionMatrixAsOrtho(bb.xMin(),bb.xMax(),bb.yMin(),bb.yMax(),1,100+abs(bb.zMax()
- bb.zMin()));
Viewer->setUpViewInWindow(x, y, width, height);
Thank you!
Cheers,
Marco
