Method Detail

classifyPointRelation(point)

Classifies the relation of a point to this plane.

Parameters:
point: Point to classify its relation.

Returns:: ISREL3D_FRONT if the point is in front of the plane, ISREL3D_BACK if the point is behind of the plane, and ISREL3D_PLANAR if the point is within the plane.

{Plane3d} clone()

Creates a clone of the plane

Returns:: {Plane3d} the cloned plane

getDistanceTo(point)

Get the distance to a point. Note that this only works if the normal is normalized.

Parameters:
point

getIntersectionWithLine(lineVect, linePoint, outIntersection)

Get an intersection with a 3d line.

Parameters:
lineVect: Vector of the line to intersect with.
linePoint: Point of the line to intersect with.
outIntersection: Place to store the intersection point, if there is one.

Returns:: True if there was an intersection, false if there was not.

getIntersectionWithPlane(other, outLinePoint, outLineVect)

Intersects this plane with another.

Parameters:
other: Other plane to intersect with.
outLinePoint: Base point of intersection line.
outLineVect: Vector of intersection.

Returns:: True if there is a intersection, false if not.

{Boolean} getIntersectionWithPlanes(o1, o2, outPoint)

Get the intersection point with two other planes if there is one.

Parameters:
o1
o2
outPoint

Returns:: {Boolean} true if intersection found, false if not

getMemberPoint()

Gets a member point of the plane.

isFrontFacing(lookDirection)

Returns true if the plane is frontfacing to the look direction.

Parameters:
lookDirection: {Vect3d} look direction

normalize()

normalizes the plane

recalculateD(mpoint)

Recalculates the distance from origin by applying a new member point to the plane.

Parameters:
mpoint

setPlane(point, nvector)

Sets initial values

Parameters:
point
nvector

setPlaneFrom3Points(point1, point2, point3)

creates a plane from 3 points

Parameters:
point1
point2
point3
