Description:
|
The part with v parameter less than that given is returned as the function value, and the supplied surface is modified to represent the remainder.
|
|
|
If the given parameter is at the beginning of the range, or before the beginning for a non-periodic surface, the function returns
NULL, and leaves the original surface unchanged (except to mark a periodic surface as "closed" instead).
|
|
|
Similarly, if the parameter is at the end of the range (or beyond for a non-periodic surface), the function returns the original surface, again unchanged except for "closed" instead of "periodic".
|
|
|
For a periodic surface, the parameter range is first adjusted by a whole number of periods to bracket the given parameter.
