virtual QList<int>* TriDecorator::getSurroundingTriangles | ( | int | pointno | ) | [virtual] |
Returns a pointer to a value list with the information of the triangles surrounding (counterclockwise) a point.
Four integer values describe a triangle, the first three are the number of the half edges of the triangle and the fourth is -10, if the third (and most counterclockwise) edge is a breakline, and -20 otherwise. The value list has to be deleted by the code which called the method. Any virtual point needs to have the number -1
