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. | ||

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 | ||

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. | ||
