Description:
|
The box will not be the smallest possible, but will be a compromise between a tight fit and fast evaluation.
|
|
|
If the parameter box is
NULL, the box will contain the whole surface.
ACIS ensures that any parameter box given is entirely within the parameter range for the surface; however, if the surface is periodic, it may be partially or wholly outside the basic range of the periodic parameter.
