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. | ||
| 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. |
