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.

Version:

06.09.99, 1.30 revised (kp) Setting of defaults for numU/VLines moved to constructor.
27.08.99, 1.20 revised (kp) Name PgDomain changed to PgDomainDescr.
04.07.99, 1.10 revised (kp) Number of u/v lines implemented as PuInteger.
Display of single parameter lines.
00.00.97, 1.00 created (kp)
