Hi,
Using osgViewer, I wanted to setup projection matrix
and modelview matrix by using intrinsic and extrinsic
parameter of a camera (which is not osg camera, but
actual camera).
My problem is that I want to rotate and translate a model
by using a matrix form (+z-axis is inward screen, i.e., opposite to
opengl),
so simply changing translation vector in the matrix by the negation
(i.e., -z) didn't
work because translation was fine at least z-axis but rotation was not.
I tested the same projection matrix and modelview matrix in OpenGL
which was working.
But not in osg or osgViewer.
Any idea? or explanation?
Cheers,
Dongpyo
