The
Intersectors Component (INTR), in the
intr directory, determines intersections between geometric elements by finding the points or intervals at which curves and surfaces meet. Intersectors operate on model geometry. Types of intersectors include:
|
|
|
Curve-curve intersectors that return a data structure containing points.
|
|
|
Curve-surface intersectors that return a data structure containing points.
|
|
|
Surface-surface intersectors that returns a data structure containing curves.
|
|
|
In addition,
INTR contains support for:
|
|
|
|
Ray testing.
|
|
|
Silhouettes.
|
|
|
Parameter lines.
|
|
|
Point classifications.
|
|
|
Body checking.
|
|
|
Curve and surface extension.
|
|
|
Face area calculation.
|
|
|
Mass properties calculation.
