DzLine3( DzLine3 line )

Copy Constructor.

DzLine3( DzVec3 origin, DzVec3 end )

Parameterized Constructor.

Parameter(s):

Object : linesIntersect( DzLine3 line, Number tolerance=0.0 )

Tests the intersection of two lines. This line and the given line are assumed to be infinitely long in both directions (i.e. the intersection can be outside the origin-end segment of either line).

Parameter(s):

• line - The line to test intersection with.
• tolerance - If not zero, specifies the maximum distance between lines that will be counted as an intersection.

Return Value:

• An object where the “intersects” property represents whether or not this line intersects with the given line, and the “intersection” property represents the intersection point if the lines intersect.

Since:

• 4.11.0.216

Object : minDistanceFromLine( DzLine3 line )

Parameter(s):

• line - The line to calculate min distance from.

Return Value:

• An object where the “distance” property represents the minimum distance between this line and another line, the “s” property represents the parametric distance along this line, and the “t” property represents the parametric distance along the given line.

Object : minDistanceFromPoint( DzVec3 pnt, Boolean clampEnds=false )

Parameter(s):

• pnt - The point to calculate the min distance from.
• clampEnds - If true, the parametric distance is clamped to the [0-1] range and the nearest point to the line segment is returned rather than the nearest distance to the infinite line formed by the two end points of the segment.

Return Value:

• An object where the “distance” property represents the minimum distance between this line and a point, and the “s” property represents the parametric distance along the line to the minimum perpendicular distance point.

• 4.11.0.216

Object : minDistanceFromPointSquared( DzVec3 pnt, Boolean clampEnds=false )

Parameter(s):

Return Value:

• An object where the “distance” property represents the minimum distance squared between this line and a point, and the “s” property represents the parametric distance along the line to the minimum perpendicular distance point.

Since:

• 4.11.0.216

Object : minDistanceFromRay( DzLine3 ray )

Parameter(s):

• ray - The ray to calculate min distance from.

Return Value:

• An object where the “distance” property represents the minimum distance between this line and a ray, the “seg_t” property represents the parametric distance along this line, and the “ray_t” property represents the parametric distance along the given ray.

• 4.11.0.216

void : negate()

Reverses the direction of the line by mirroring the endpoint.

Object : planeIntersect( DzVec3 planePoint, DzVec3 planeNormal )

Calculates the intersection of this line and the plane specified. The plane is defined by a point on the plane and the normal to the plane.

Parameter(s):

• planeNormal - The normal to the plane (to define the plane).

Return Value:

• An object where the “intersects” property represents whether or not this line intersects with the given plane, the “t” property represents the parametric distance along this line to the intersection point (if there is one), and the “intersection” property represents the intersection point if the line and plane intersect.
