Constructor & Destructor Documentation

◆ SbLine() [1/2]

SbLine::SbLine ( )
inline

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

Definition at line 1296 of file SbLinear.h.

◆ SbLine() [2/2]

SbLine::SbLine ( const SbVec3f &  p0,
const SbVec3f &  p1 
)

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