vcVector
vcVector is a 4x1 column vector and is generally used to define joint lengths in robots, offsets and directions, and angles of rotation.
Constructors
| Name | Return Type | Parameters | Description |
| new | vcVector | vcVector vector
or Real x, Real y, Real z or Real x, Real y, Real z, Real w or None |
Creates a new vcVector object.
One option allows you to give an existing vector, thereby creating a copy. A second option allows you to give three components for new vector. A third option allows you to give four components for new vector. A fourth option allows you to give no arguments, thereby creating a zero vector. |
Operators
| Name | Description |
| * | Allows you to get the dot product of vectors. |
| ^ | Allows you to get the cross product of vectors. |
| + | Allows you to add vectors. |
| - | Allows you to subtract vectors. |
Properties
| Name | Type | Access | Description |
| W | Real | RW | Defines w-component (fourth element) of vector. |
| X | Real | RW | Defines x-component (first element) of vector. |
| Y | Real | RW | Defines y-component (second element) of vector. |
| Z | Real | RW | Defines z-component (third element) of vector. |
Methods
| Name | Return Type | Parameters | Description |
| angle | Real | vcVector vector | Returns the angle (in radians) between vector and a given vector. |
| getQuaternionAngle | vcVector | vcVector vector | Returns the quaternion angle between vector and a given vector. |
| length | Real | None | Returns the magnitude (length) of vector. |
| normalize | None | None | Normalizes vector. |
| square | Real | None | Returns the square of vector. |
Examples
Example. Relocate component using position vector
| from vcScript import * import vcVector comp = getComponent() vec = vcVector.new(100.0,200.0,300.0) # creates a new vcVector object m = comp.PositionMatrix m.P = vec # assign the vector to position vector for matrix comp.PositionMatrix = m getApplication().render() |
