Constructor & Destructor Documentation

◆ SbLined() [1/2]

SbLined::SbLined ( )
inline

To construct a line from a position and direction, use: SbLined(p0, p0 + dir). The line is directed from p0 to p1.

◆ SbLined() [2/2]

SbLined::SbLined ( const SbVec3d & p0,
const SbVec3d & p1 )

To construct a line from a position and direction, use: SbLined(p0, p0 + dir). The line is directed from p0 to p1.
