Detailed Description

Represents a line in 3D space.

The line is represented using Plücker coordinates. A line is represented by two vectors U and V. U is the direction of the line, and the cross product of U and any point on the line is equal to V.

Member Function Documentation

bool GAUGE3D::GLine::FindIntersection ( GVector * result, const GLine & other ) const

Find intersection between two lines. Parameters: result   Pointer to a vector which should be overwritten with the point of intersection. If NULL, it will not be overwritten. other   The line with which to test for intersection. Returns: True if a point of intersection was found, or false if the lines did not intersect or if they were equal.

bool GAUGE3D::GLine::Contains ( const GVector & point ) const [inline]

test if a point is on the line. Returns: True if the given point was on the line or false otherwise.

GCoordinate GAUGE3D::GLine::FindSquareDistance ( const GVector & point ) const

Finds the square of the shortest distance between the line and a point (faster). This is faster because no square root needs to be performed.

GCoordinate GAUGE3D::GLine::FindSquareDistance ( const GLine & point ) const

Finds the square of the shortest distance between two lines (faster). This is faster because no square root needs to be performed.
