Hand

Extended SubModel

A hand is a specific type of part. HandModel inherits from PartModel. Therefore, it contains extra variables that are described bellow:

References

• Bones: Wrist bone.

• Parts: Thumb, index, middle, ring and pinky fingers.

• Points: Palm points, ray and midpoints.

Palm points

• Palm center: Most interior point of the surface of the hand. For both hands:

  • Right direction (red) goes from palm center to wrist.

  • Up direction (green) goes from palm center to thumb knuckle.

• Palm normal: Point that shares same position as palm center but with different rotation. For both hands:

  • Forward direction (blue) matches normal vector of palm surface.

• Palm exterior: Palm line point under pinky knuckle.

• Palm interior: Palm line point under index knuckle.

• Pinch center: Midpoint between thumb tip and index tip.

• Throat center: Midpoint between thumb knuckle and index knuckle.

• Ray: Point where forward vector of each of its representations represents the direction the hand is pointing towards.
