Camera.extrinsic_matrix

property Camera.extrinsic_matrix: NumpyArray[float]

Return or set the pose of the camera as a 4x4 extrinsic matrix.

The matrix maps world coordinates to camera coordinates in the OpenCV convention, with x to the right, y down and z along the viewing direction. Invert it for the camera-to-world pose. It describes the camera alone and does not include model_transform_matrix.

Setting the matrix keeps the camera’s distance to its focal point.

Added in version 0.50.
