confuse about num_orientations #65

@atenpas Hi ! if I set the num_orientations to 1,Whether it will only generate vertical grasp?

atenpas commented 5 years ago

No, it will not necessarily generate a vertical grasp. The grasp's orientation depends on an estimation of a local reference frame (see our paper for more details).

The orientations are generated about the hand axis (blue axis in image below).

Grasp frame

Here's an example with _numorientations = 4.
