i want view matrix using .nt api. I am able to get model view matrix using modelview->orientation3 but i need view matrix,
There may be an alternative way, but if you hook into the BufferSwapNotify event, then you can access the openGL projection and view matrices.
Using OpenTK, the C# code is:
GL.GetFloat(GetPName.ModelviewMatrix, out Matrix4 openGLModelViewMatrix);GL.GetFloat(GetPName.ProjectionMatrix, out Matrix4 openGLProjectionMatrix);
EDIT: Maybe just IModelVIew.Transform is what you are looking for.
