DESCRIPTION
Represents a directed line in 3D. This is a basic Inventor datatype that is used for representing a 3D line. It is used as input and output by a variety of Inventor classes.

METHODS

SbLine()

SbLine(const SbVec3f &p0, const SbVec3f &p1)
Constructors. To construct a line from a position and direction, use: SbLine(p0, p0 + dir). The line is directed from p0 to p1.

void
setValue(const SbVec3f &p0, const SbVec3f &p1)
Sets line to pass through points p0 and p1.

SbBool
getClosestPoints(const SbLine &line2, SbVec3f &ptOnThis, SbVec3f &ptOnLine2 ) const
Finds the two closest points between this line and line2, and loads them into ptOnThis and ptOnLine2. Returns FALSE if the lines are parallel (results undefined), and returns TRUE otherwise.

SbVec3f
getClosestPoint(const SbVec3f &point) const
Returns the closest point on the line to the given point.

const SbVec3f &
getPosition() const
const SbVec3f &
getDirection() const
Returns position of line origin point and direction vector of line.
