Other Methods on Surface

 

     

SURFACE * surface

Compute the lengths of the boundary curves resp. the periods (if any) for all model frames and inter using the same methods on Geom2d (see 6.3.4.5).

           

SURFACE * surface

Additional to the superclass methods described in section 7.4.1.8 these methods also handle the geometries domain, gauss and conjugate. "reset-send" also deletes reflected instances.

   GRAPE(surface, "universal")(method)

SURFACE * surface
char * method

As the superclass method (see 7.4.1.8) display methods are send to the inter instance but other methods are send to the model instead of the geometry.

     

SURFACE * surface
XLIST * xlist
INSTANCE * follow[3][3]
char pop_push[3][3]

Refer to section 5.4.7.3 for and explanation of the "get-info" and "follow" methods.

"get-info" adds information about the * asso value and the number of points and elements of the Geom2d instances of the Surface geometries to the superclass data.

"follow" adds the domain (top right), model (right) and conjugate (bottom right) geometries to the surface's environment in the manager.

   GRAPE(surface, "find-pick")(v, u, w, obj, dist)

SURFACE * surface
VEC3 v
double u, w
INSTANCE **obj
double * dist

"find-pick" allows to pick a point in the current inter Chain of objects (if it doesn't exist * obj is set to NULL), the object and point found are returned in obj and v. This method uses "find-pick" on Scene (7.1.1.1) and Triang2d (6.3.1.4).

   GRAPE(surface, "debug")()

SURFACE * surface

Interactive debugging for Surface instances: points or objects can be picked with the mouse to get information about their coordinates, index, and transformation.

   (CHAIN * ) GRAPE(surface, "get-bnd-curve")(chain)

SURFACE * surface
CHAIN * chain

Extract the time-dependent boundaries from the surface's model Geom2d instances and copy them to chain. chain is returned, if it is NULL a new Chain instance is created.
