Subject: [osg-users] How to implemente this simple function?
Hello all :
I want to implemente this function, only to render the fixed distance from
the viewer current position, and I can't use the getProjectionMatrixAsFrustum
function correct:
I use the following codes, but the result is very strange:
viewer ->getCamera() ->setProjectionMatrixAsFrustum(-10,10,-10,10,100,200) ;
I want the viewer only to render the distance between 100 and 200 from the
viewer current position.
I will gratitude for giving me some Tutorials
......... Sorry for my poor EN.
