2.7.9.2 Vector functions and macros

These are all macros in the current version because functions can not take vector parameters, but this may change in the future.

VSqr(V). Square each individual component of a vector, equivalent to V*V.
Parameters:

• V = Vector to be squared.

VPow(V, P), VPow5D(V, P). Raise each individual component of a vector to a given power.
Parameters:

• V = Input vector.
• P = Power.

VEq(V1, V2). Tests for equal vectors, returns true if all three components of V1equal the respective components of V2.
Parameters:

• V1, V2 = The vectors to be compared.

VEq5D(V1, V2). A 5D version of VEq(). Tests for equal vectors, returns true if all 5 components of V1 equal the respective components of V2.
Parameters:

• V1, V2 = The vectors to be compared.

VZero(V). Tests for a < 0, 0, 0> vector.
Parameters:

• V = Input vector.

VZero5D(V). Tests for a < 0, 0, 0, 0, 0> vector.
Parameters:

• V = Input vector.

VLength5D(V). Computes the length of a 5D vector.
Parameters:

• V = Input vector.

VNormalize5D(V). Normalizes a 5D vector.
Parameters:

• V = Input vector.

VDot5D(V1, V2). Computes the dot product of two 5D vectors. See vdot() for more information on dot products.
Parameters:

• V = Input vector.

VCos_Angle(V1, V2). Compute the cosine of the angle between two vectors.
Parameters:

• V1, V2 = Input vectors.

VAngle(V1, V2), VAngleD(V1, V2). Compute the angle between two vectors. VAngle() returns the angle in radians, VAngleD() in degrees.
Parameters:

• V1, V2 = Input vectors.

VRotation(V1, V2, Axis), VRotationD(V1, V2, Axis).Compute the rotation angle from V1 to V2 around Axis. Axis should be perpendicular to both V1 and V2. The output will be in the range between -pi and pi radians or between -180 degrees and 180 degrees if you are using the degree version. However, if Axis is set to <0,0,0> the output will always be positive or zero, the same result you will get with the VAngle() macros.
Parameters:

• V1, V2 = Input vectors.

VDist(V1, V2). Compute the distance between two points.
Parameters:

• V1, V2 = Input vectors.

VPerp_To_Vector(V). Find a vector perpendicular to the given vector.
Parameters:

• V = Input vector.

VPerp_To_Plane(V1, V2). Find a vector perpendicular to both given vectors. In other words, perpendicular to the plane defined by the two input vectors
Parameters:

• V1, V2 = Input vectors.

VPerp_Adjust(V1, Axis). Find a vector perpendicular to Axis and in the plane of V1 and Axis. In other words, the new vector is a version of V1 adjusted to be perpendicular to Axis.
Parameters:

• V1, Axis = Input vectors.

VProject_Plane(V1, Axis). Project vector V1 onto the plane defined by Axis.
Parameters:

• V1 = Input vectors.
• Axis = Normal of the plane.

VProject_Axis(V1, Axis). Project vector V1 onto the axis defined by Axis.
Parameters:

• V1, Axis = Input vectors.

VMin(V), VMax(V). Find the smallest or largest component of a vector.
Parameters:

• V = Input vector.

VWith_Len(V, Len). Create a vector parallel to a given vector but with a given length.
Parameters:

• V = Direction vector.
• Len = Length of desired vector.
