Arm Manipulations
Arm Manipulations
Consider a parametric arm of a constant length capable of any 3D operation. This Demonstration illustrates three fundamental spatial transformations of such an arm:
1. Flexure—continuous bending from a straight segment to a full circle.
2. Translation—a particular shape (a semicircle) travels along the arm.
3. Extension—two ends of the arm extend or contract.
The operations are controlled by a single parameter .
