Keep original direction from content motion

[LeVan146]

Hi guys @kfiraberman @PeizhuoLi, I would be grateful if you can show me how to keep the original direction from content motion?

deep-motion-editing/utils/animation_data.py

Lines 211 to 226 in 74fff8f

	def y_rotation_from_positions(positions, hips=(2, 6), sdrs=(14, 18)):
	"""
	input: positions [T, J, 3]
	output: quaters: [T, 1, 4], quaternions that rotate the character around the y-axis to face [0, 0, 1]
	pivots: [T, 1] in [0, 2pi], the angle from [0, 0, 1] to the current facing direction
	"""
	across = across_from_glb(positions, hips=hips, sdrs=sdrs)
	direction_filterwidth = 20
	forward = np.cross(across, np.array([[0, 1, 0]]))
	forward = filters.gaussian_filter1d(forward, direction_filterwidth, axis=0, mode='nearest')
	forward = forward / np.sqrt((forward ** 2).sum(axis=-1))[..., np.newaxis]
	target = np.tile(np.array([0, 0, 1]), forward.shape[:-1] + (1, ))
	quaters = Quaternions.between(forward, target)[..., np.newaxis, :] # [T, 4] -> [T, 1, 4]
	pivots = Pivots.from_quaternions(-quaters).ps # from "target"[0, 0, 1] to current facing direction "forward"
	return quaters, pivots

Hi, I'm not sure if understand correctly your question or not.

The code you referred to is taken from Holden's work as described here. We might not be able to provide help on exterior code.
