Transform a 3D point of a source coordinate system into a 3D point of the target coordinate system.

calibrationLocation to read the camera calibration data.
source_point3d_mmThe 3D coordinates in millimeters representing a point in source_camera.
source_cameraThe current camera.
target_cameraThe target camera.
target_point3d_mmPointer to the output where the new 3D coordinates of the input point in the coordinate space of target_camera is stored in millimeters.
K4A_RESULT_SUCCEEDED if target_point3d_mm was successfully written. K4A_RESULT_FAILED if calibration contained invalid transformation parameters.
This function is used to transform 3D points between depth and color camera coordinate systems. The function uses the extrinsic camera calibration. It computes the output via multiplication with a precomputed matrix encoding a 3D rotation and a 3D translation. If source_camera and target_camera are the same, then target_point3d_mm will be identical to source_point3d_mm.
