Class Summary
class RiConvexHull
{
}; // RiConvexHull
DESCRIPTION
Abstract away the notion of the region of space and RiRadObject occupies. Allows
any object to do visibility checks on any other object without
knowing what the other object is.
IMPLEMENTATION
Currently this is implement with a maximum number of points of 8. After 8, the
hull is represented as a bounding box of the points.
RiConvexHull();
Default Constructor
RiConvexHull();
void AddPoint(const RiVector3 &pnt);
Add a point to the hull. The resulting hull will contain all previous points, even if they aren't stored explicitly.
void AddPoint(const RiVector3 &pnt);
RiVector3 GetPoint(int i) const;
Get a point defining the hull
RiVector3 GetPoint(int i) const;
int GetNumPoints() const;
Get the number of points defining the hull (<= number added)
int GetNumPoints() const;
