C --*** QNPICK *** (MESH) Query last mesh display for node information

|
C --QNPICK returns the address of the last displayed mesh characteristics
|
||
|
|
C --for cursor input. This routine assumes that the characteristics
|
||
|
|
C --are in dynamic memory.
|
||
|
|
C --
|
||
|
|
C --This routine uses MDFIND to find the following dynamic memory arrays:
|
||
|
|
C -- XN, YN, ZN - the nodal coordinates (ZN for 3D only)
|
||
|
|
C -- DHZ, DVT, DPD - the deformed nodal coordinates (DPD for 3D only)
|
||
|
|
C -- HIDENP - true iff node i is hidden (3D only)
|
||
|
|
C -- NPSURF - the node numbers of the surface nodes (3D only)
|
||
|
|
C --
|
||
|
|
C --Parameters:
|
||
|
|
C -- TYPE - IN - the type of mesh information needed:
|
||
|
|
C -- 'QUERY' - return ISUP and ISDEF only
|
||
|
|
C -- 'ORIGINAL' - original mesh coordinates
|
||
|
|
C -- 'DISPLAYED' - last displayed mesh coordinates
|
||
|
|
C -- ISUP - OUT - true iff a mesh is displayed
|
||
|
|
C -- ISDEF - OUT - true iff the displayed mesh is deformed
|
||
|
|
C -- A - IN - the dynamic memory base array
|
||
|
|
C -- KXN, KYN, KZN - OUT - the dynamic memory index of the coordinates
|
||
|
|
C -- requested (KZN in 3D only)
|
||
|
|
C -- KHIDEN - OUT - the dynamic memory index of the node hidden indicator
|
||
|
|
C -- (3D only)
|
||
|
|
C -- KNPSUR - OUT - the dynamic memory index of the surface node indices
|

|
|
C -- (3D only)
