Point to Deformable Curve (PTDCV)
The point to deformable curve joint constrains a fixed point on a body to slide along a curve that passes through the origins of a specified set of markers. These markers may belong to different bodies. As the markers move in space, the curve is calculated at every time step using CUBIC spline interpolation through the marker origins. Hence, the curve deforms as the markers move about.
- Two reference surface entities (created using the Surfaces panel).
- Two markers that belong to Body 1 and Body 2 of the joint and are located appropriately so that the surface entity can be meaningfully described as belonging to the coordinate system of the reference marker.
