- This experiment introduces the concept of the hierarchical transformations and a hierarchical model.
- The hierarchical articulated arm is provided. Notice the different nodes used to construct the model. The nodes in this model follows the hierarchy: Shoulder (highest), Elbow, Forearm, Wrist and Palm. Applying transformations to a node in the hierarchy applies the same transformations to all the lower nodes in the hierarchy in addition to their own transformations. For example, a rotation has been applied to the shoulder. As you drag the slider you can notice this rotation being applied to the other nodes toother nodes.
- Try modifying the transformations in the hierarchy and notice the effective changes on the entire model.
- Open the transormation nodes of Forearm and Palm and notice how a Cube has been moulded to a forearm and a palm using the respective transformations.
