Display Methods on Geom2d

 

   GRAPE(geom, "display")()

GEOM2D * geom

Display a Geom2d instance on the standard graphicdevice as a patch or as a grid model. If geom is displayed in patch mode and normal is NULL or GEOM2D_USERNORM is not set in flag then normals are computed by calling "compute-normals-send".

The geom-> flag controls which parts of geom are displayed:

                       

GEOM2D * geom

Add GEOM2D_-flags (see the Geom2d structure above) to or remove them from geom-> flag. Surface, boundary curves and horizontal or vertical parameters lines are only displayed if the corresponding flag is set.

To display boundary curves or parameter lines independent from geom-> flag the following methods can be used:

        

GEOM2D * geom

Display the boundary lines or the horizontal or vertical parameter lines.

     

GEOM2D * geom
double length

Display the geom together with its normals. If the GEOM2D_USERNORM flag is not set the normals are computed with "compute-normals-send". The normals are drawn as lines with length length, the interactive method "normals-disp" adds a ruler to the manager which allows to edit this length.

   GRAPE(geom, "refine-display")()

GEOM2D * geom

Display the edges that would be refined and the edges that would be created by calling "refine(-send)". This method extends the superclass method (see 6.3.3.2), it allows to display boundary curves or parameter lines.
