Information

Model Surface defines a moveable, parametrized surface in 3-dim. space that is used for animation. This object is specified by:

• The surface frame (orientation object "R" and origin "r_0") in which the data is specified.
• A set of two parameters, one in u- and one in v-direction, that defines the control points.
• A time-varying position of each control point with respect to the surface frame.

The parameter values (u,v) are given by the ordinal numbers of the corresponding control point in u- or in v-direction, respectively. The surface is then defined by the replaceable function "surfaceCharacteristic" with the interface partialSurfaceCharacteristic that returns the x-, y-, z- coordinate of every control point in form of 3 positional arrays and an optional color array, if every control point shall have a different color:

  Real X[nu,nv], Y[nu,nv], Z[nu,nv], colorArray[nu,nv];

Models Torus and VoluminousWheel demonstrate how new visualizer objects can be constructed with the Surface model.
The direct usage of the Surface model, as well as of the Torus and the VoluminousWheel models, are demonstrated with example Examples.Elementary.Surfaces.
