IsVectorParallelTo

Compares two vectors to see if they are parallel.

Rhino.IsVectorParallelTo (arrVector1, arrVector2)

arrVector1	Required. Array. The 3D vector.
arrVector2	Required. Array. The 3D vector to compare to.

Number

The result of the comparison if successful. The possible results are as follows:

-1	The vectors are anti-parallel.
0	The vectors are not parallel.
1	The vectors are parallel.

Null

On error.

Dim arrVector1, arrVector2

arrVector1 = Array(1,0,0)

arrVector2 = Array(0,1,0)
