- Parameters:
-
key | - Unique numeric identifier pointing to a circular wedge in the database. |
point1 | - An x-y-z triplet for the coordinates of one of three on the circumference of the circle. (A simple array of three elements can also be used in most languages.) Returned to user. Passed by reference always. |
point2 | - As above. |
point3 | - As above. |
DETAILS
This routine finds the three points used to define the wedge that corresponds to the given key. You could use this ability, for example, to extract data needed to construct a line tangent to an existing wedge. The key for the wedge might come from Show_Selection_Element() or Find_Contents() , or it might have been saved by your program when the wedge was created
