| * Convert standard camera intrinsic and extrinsic parameters to a vtkCamera instance for rendering | |
| * Assume square pixels and 0 skew (for now). | |
| * | |
| * focal_len : camera focal length (units pixels) | |
| * nx,ny : image dimensions in pixels | |
| * principal_pt: camera principal point, | |
| * i.e. the intersection of the principal ray with the image plane (units pixels) | |
| * camera_rot, camera_trans : rotation, translation matrix mapping world points to camera coordinates | |
| * depth_min, depth_max : needed to set the clipping range |
