Hi, I'm trying to implement something similar to:
http://linuxtoosx.blogspot.com/2010/06/fishtank-vr-project-with-opencv-and_30.html When I'm doing that using OpenGL only, I'm getting satisfactory results. The code is exactly the same as the one suggested on the website, Code: glMatrixMode(GL_PROJECTION); glLoadIdentity(); glFrustum(-0.5 + x, 0.5 + x, -0.5 + y, 0.5 + y, nearPlane - z, 100.0); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glTranslatef(x, y, z); But when I try to achieve the same result in OSG, the output is not exactly the same, currently I'm using the following code: Code: osgViewer.getCamera()->setProjectionMatrixAsFrustum(-0.5 + x, 0.5 + x, -0.5 + y, 0.5 + y, nearPlane - z, 100.0); osg::Matrixd cameraTrans; cameraTrans.makeTranslate(x, y, z); osgViewer.getCamera()->setViewMatrix(cameraTrans); Is that equivalent to the OpenGL implementation? Or am I missing something? Thank you!
