Macro Definition Documentation

MODELNUM_LEN

#define MODELNUM_LEN   (XRT_DEVICE_NAME_LEN + 9)

When set, all controllers pretend to be Index controllers.

Provides best compatibility with legacy games due to steamvr's legacy binding for Index controllers, but input mapping may be incomplete or not ideal.

Function Documentation

metacarpal_joints_to_bone_transform()

void metacarpal_joints_to_bone_transform	(	struct xrt_hand_joint_set *	hand_joint_set,
		vr::VRBoneTransform_t *	out_bone_transforms,
		xrt_hand	hand
	)

• if you try applying the metacarpal transforms without the magic quaternion, everything from the metacarpals onwards is rotated 90 degrees. In the neutral pose sample, all the metacarpals have a rotation relatively close to {w=0.5, x=0.5, y=-0.5, z=0.5} which is an Important Quaternion because it probably represents some 90 degree rotation. Maybe, and this was just a random guess, if I took the regular metacarpal orientations and rotated them by that quat, everything would work.
