Inheritance:

Public Fields

static double

epsilon the confidence interval that is considered for detecting intersections between primitives

Public Methods

static double	pointToLine (const Vec3& org, const Vec3& dir, const Vec3& point) returns the distance between a 3D point and a 3D Line
static double	segmentToLine (const Vec3& org, const Vec3& dir, const Vec3& segA, const Vec3& segB) returns the distance between a 3D line and a 3D segment
static double	triangleToLine (const Vec3& org, const Vec3& dir, const Vec3& trA, const Vec3& trB, const Vec3& trC) returns the distance between a 3D line and a triangle

static double pointToLine(const Vec3& org, const Vec3& dir, const Vec3& point)

returns the distance between a 3D point and a 3D Line

Returns:

the distance between the 3D point and the 3D line

Parameters:

org - a point on the 3D line
dir - the direction vector of the 3D line (may not be unit vector )
point - the 3D point

static double segmentToLine(const Vec3& org, const Vec3& dir, const Vec3& segA, const Vec3& segB)

returns the distance between a 3D line and a 3D segment

Returns:

the distance between the 3D line and the 3D segment

Parameters:

org - a point on the 3D line
dir - the direction vector of the 3D line (may not be unit vector )
segA - the first segment extremity
segB - the second segment extremity

static double triangleToLine(const Vec3& org, const Vec3& dir, const Vec3& trA, const Vec3& trB, const Vec3& trC)

returns the distance between a 3D line and a triangle

Returns:

the distance between the 3D line and the triangle

Parameters:

org - a point on the 3D line
dir - the direction vector of the 3D line (may not be unit vector )
trA - the first triangle vertex
trB - the second triangle vertex
trC - the third triangle vertex
