public class MySurface

extends PgElementSet

Subclass of geometry class PgElementSet for demonstration. Default functions describe a catenoid, which can be deformed into a helicoid. This class has two methods to compute the vertices of the surface and the mesh connectivity. Another method is used to compute the vertices during the animation depending on an animation parameter.

Method Detail

computeSurface

public void computeSurface(int numULines,
                           int numVLines)

Compute static surface with given discretization. Connectivity is generated for a quadrilateral mesh. Method is synchronized with computeAnimation() to avoid conflicts between animation and user interaction via panel.

makeQuadrConn

public void makeQuadrConn(int uDiscr,
                          int vDiscr)

Generate element and neighbourhood information for a quadrilateral surface. Method generates only topological information, no coordinates are required.

Current method is copied 1-1 from PgElementSet just as tutorial example. Usually, the connectivity is calculated automatically by methods like this.

Overrides:

makeQuadrConn in class PgElementSet

Parameters:

uDiscr, - vDiscr Number of lines in u and v direction.

See Also:

PgElementSet.makeCylinderConn(int, int)

computeAnimation

public void computeAnimation(double a)

Compute new surface depending on parameter which varies in time. Connectivity is not computed since it does not change since last call to computeSurface(int, int). Animated surface is an interpolation between a catenoid and a helicoid. Method is synchronized with computeAnimation() to avoid conflicts between animation and user interaction via panel.
