Class PgDomainDescr

java.lang.Object

jv.object.PsObject

jvx.surface.PgDomainDescr

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, PsUpdateIf

Direct Known Subclasses:

PgSurfaceDescr

public class PgDomainDescr
extends PsObject

Two-dimensional domain for parametrized surfaces with variable size and discretization. Info panel allows to adjust size and discretization of domain and grid. The domain in R^2 is the rectangle [uMin,vMin]x[uMax,vMax] with numULines resp. numVLines grid lines in u-horizontal resp. v-vertical direction.

Single parameter lines may be displayed by linking uMin and uMax resp vMin and vMax together.
