SW_getExtent
A library function which returns the size of the smallest rectangle, orthogonal to the
axes, which contains the specified element. An extent is different from a bounding box,
because a bounding box is not necessarily orthogonal to the axes.
package require SW
SW_getExtent elementID [sceneID]
- elementID
- the element whose extent will be returned.
- sceneID
- The scene in which the element occurs. This is an optional parameter. If it is missing
then the current scene is the default.
Return Value
If the function succeeds it returns a list defining the extent. The returned lists
consists of six numeric elements, namely: minx,maxx,miny,maxy,minz and maxz. If an error
occurs the procedure returns a string describing that error.
