# Point and Vector Methods

This guide provides an overview of the RhinoScriptSytntax Point and Vector methods.

## 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.
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
PullPoints     Pulls points to a surface or a mesh object.
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.
VectorUnitaze     Unitizes, or normalizes, a vector.
