• fov - The horizontal field of view in radians.
• orthographic - Enable to have orthographic projection instead of perspective (RenderView::fov doesn’t matter in this case, in favor of RenderView::orthographicWidth).
• transform - A transformation (rotation + translation) which defines where the camera is and how it is rotated. The matrix is in column-major format and you will need to calculate it yourself. You can't set rotation angles as in most 3D software. The default camera orientation with identity matrix is so that +Y is pointing up and -Z is the view direction. If your scene uses +Y for up-axis, you will need to set V-Ray's scene up-axis accordingly - see the Units subsection in the settings section below.
