cgal_dt3_delete - Delete a pointer that represent dt3.

Calling Sequence

cgal_dt3_delete(ptr,"ptr");
cgal_dt3_delete();

Parameters

Description

Given a pointer ptr of dt3, cgal_dt3_delete(ptr,"ptr") frees the memory holded by the pointer ptr and clears ptr in Scialb interpreter. if no parameters are given to cgal_dt3_delete(), then, all pointers of differents dt3 will be deleted.

Examples



x = rand(1,10);
y = rand(1,10);
z = rand(1,10);
new_x = rand(1,10);
new_y = rand(1,10); 
new_z = rand(1,10); 
//example 1:

[tri,ptr] = cgal_delaunay_3(x,y,z);
cgal_dt3_insert_points(ptr,new_x,new_y,new_z);
new_tri = cgal_dt3_get_connectivity(ptr);
cgal_dt3_delete(ptr,"ptr"); // ptr is deleted here and cleared from scilab interpreter.
ptr
  !--error     4
undefined variable : ptr 
//example 2:
[tri1,ptr1] = cgal_delaunay_3(rand(1,10),rand(1,10),rand(1,10));
clear ptr1; // ptr is not yet defined in scilab interpreter, but the memory is not freed.
cgal_dt3_delete(); // all pointers of dt3 will be deleted.
