blendersynth.annotations.utils.project_point_to_image(P, scene, camera, invert_y=True)

Return 2D (x, y) image coordinates of a 3D point P.

Parameters:

• P (Vector) – 3D point

• scene (Scene) – Blender scene

• camera (Camera) – Camera to project through

• invert_y (bool) – if True, y is measured from the top of the image, otherwise from the bottom (Blender measures from bottom)

blendersynth.annotations.utils.project_points(points, scene, camera, invert_y=True)

Project points to image plane.

Parameters:

• points (ndarray) – Nx3 matrix of points

• scene (Scene) – Blender scene

• camera (Camera) – Camera to project through

• invert_y (bool) – if True, y is measured from the top of the image, otherwise from the bottom

Returns:

Nx2 matrix of 2D image coordinates
