Description:
|
||
|
|
Test the box to see if it is degenerate (flat)
|
||
|
|
in one or more directions.
|
||
|
|
Parameters:
|
||
|
|
tolerance - [in] Distances <= tolerance will be considered
|
||
|
|
to be zero. If tolerance is negative (default), then
|
||
|
|
a scale invarient tolerance is used.
|
||
|
|
Returns:
|
||
|
|
@untitled table
|
||
|
|
0 box is not degenerate
|
||
|
|
1 box is a rectangle (degenerate in one direction)
|
||
|
|
2 box is a line (degenerate in two directions)
|
||
|
|
3 box is a point (degenerate in three directions)
|

|
|
4 box is not valid
