VectorGeoc3D
(For high level concepts about how to use Lua to write scripted tasks, please see VR-Forces User's Guide.)
A VectorGeoc3D is a straight line in space, unlike a Vector3D. The coordinate system is not accessible to a Lua script, but it can be thought of as a vector in geocentric coordinates. There is no constructor for this type of vector in Lua, as the coordinate system is abstracted away. These vectors are only created as a result of operations on locations.
Function List
| crossVectorGeoc3D (geocVector) | Creates a vector that is the cross product of this vector with the given vector, i.e. |
| dotVectorGeoc3D (geocVector) | Computes the dot product of this vector with the given one. |
| getLength () | Computes the length of this vector. |
| getNegated () | Creates a vector that is the negation of this vector. |
| getScaled (scale) | Creates a scaled version of this vector. |
| getUnit () | Creates a unit vector of this vector, i.e. |
| makeCopy () | Makes a copy of the given vector object. |
| makeVector3DAtLoc (location) | Creates a Vector3D with the same direction as this vector, at the given location. |
Functions
- crossVectorGeoc3D (geocVector)
-
Creates a vector that is the cross product of this vector with the given vector, i.e. this x offsetVector.
Parameters:
-
geocVector: A VectorGeoc3D
Return value:
- A VectorGeoc3D
-
- dotVectorGeoc3D (geocVector)
-
Computes the dot product of this vector with the given one.
Parameters:
-
geocVector: A VectorGeoc3D
Return value:
- A number that is the dot product of this vector with the given vector.
-
- getLength ()
-
Computes the length of this vector.
Return value:
- The length of the vector.
- getNegated ()
-
Creates a vector that is the negation of this vector.
Return value:
- A VectorGeoc3D which is this vector negated.
- getScaled (scale)
-
Creates a scaled version of this vector. I.e. one whose length is this vector's length times scale.
Parameters:
-
scale: A number that this vector is multiplied by to produce the output vector.
Return value:
- A VectorGeoc3D which is this vector scaled by the input scale.
-
- getUnit ()
-
Creates a unit vector of this vector, i.e. this / |this| .
Return value:
- A VectorGeoc3D which is a unit vector of this vector.
- makeCopy ()
-
Makes a copy of the given vector object.
Return value:
- VectorGeoc3D that is a copy of this object.
- makeVector3DAtLoc (location)
-
Creates a Vector3D with the same direction as this vector, at the given location.
Parameters:
-
location: A Location3D
Return value:
- A Vector3D
