Point & Vector Methods

The following methods are available for creating and manipulating 3-D points and 3-D vectors. 3-D points and 3-D vectors are represented as zero-based, one-dimensional arrays that contain three numbers. For more information, see the Points and Vectors discussion in RhinoScript Fundamentals.

Method	Description
IsVectorParallelTo	Compares two vectors to see if they are parallel.
IsVectorPerpendicularTo	Compares two vectors to see if they are perpendicular.
IsVectorTiny	Verifies a vector is tiny.
IsVectorZero	Verifies a vector is zero.
PointAdd	Adds a point or a vector to a point.
PointArrayBoundingBox	Returns the bounding box of an array of 3-D points.
PointArrayClosestPoint	Finds the point in an array of 3-D points that is closest to a test point.
PointArrayTransform	Transforms an array of 3-D points.
PointClosestObject	Finds the object that is closest to a test point.
PointCompare	Compares two points.
PointDivide	Divides a point by a value.
PointsAreCoplanar	Verifies that a list of 3-D points are coplanar.
PointScale	Scales a point by a value.
PointSubtract	Subtracts a point or a vector from a point.
PointTransform	Transforms a point.
ProjectPointToMesh	Projects one or more points onto one or more meshes.
ProjectPointToSurface	Projects one or more points onto one or more surfaces or polysurfaces.
PullPoints	Pulls points to a surface or a mesh object.
VectorAdd	Adds two vectors.
VectorAngle	Returns the angle between two 3-D vectors.
VectorCompare	Compares two vectors.
VectorCreate	Create a vector from two 3-D points.
VectorCrossProduct	Returns the cross product of two vectors.
VectorDivide	Divides a vector.
VectorDotProduct	Returns the dot product of two vectors.
VectorLength	Returns the length of a vector.
VectorMultiply	Multiplies two vectors.
VectorReverse	Reverses a vector.
VectorRotate	Rotates a vector.
VectorScale	Scales a vector.
VectorSubtract	Subtracts two vectors.
VectorTransform	Transforms a vector.
