Methods on other classes related to meshes

   

(HMESH2D_LENS *)GRAPE(lens, "get-lens")(name)

HMESH2D_LENS *lens
char *name

This method creates a new instance of Class Hmesh2d_Lens with name given as parameter name and initializes it with default values. In particular the estimators and thresholds are set to default-functions. The lens is assigned to an own interactive layer which allows to manipulate the lens-parameters.

   

(HMESH2D_LENS *)GRAPE(lens, "display")()

HMESH2D_LENS *lens

This method draws an icosaeder related to the parameters of the lens as a wire-frame-model. The center is the entry coord of the instance lens. The radius is a convex-combination depending on show_threshold between the inner and outer region of the mesh.

   

(MESH2D *)GRAPE(sc, "convert-to-mesh-send")()

SCENE *sc

This method tries to convert the instance scobject to one of class Mesh2d. If successful, this new instance is taken as sc's object. The old structure is still accessible via the created mesh's user_data pointer.

   

(MESH2D *)GRAPE(tr, "convert-to-mesh2d")()

TRIANG2D *tr

This method generates a Mesh2d instance based on the data of tr. Especially the original Triang2d structure remains unchanged and is accessible from the returned mesh via its user_data pointer. The resulting mesh carries no functions.

   

(MESH2D *)GRAPE(fe, "convert-to-mesh2d")()

FE2D *fe

This method generates a Mesh2d instance based on the data of fe. Especially the original Fe2d structure remains unchanged and is accessible from the returned mesh via its user_data pointer.
