UnitQuaternion Constructor (Double, Int32)

Initializes a set of UnitQuaternion coordinates from 4 consecutive elements in the provided array. Note that the elements will not be normalized and may represent an invalid unit quaternion.

Namespace:  AGI.Foundation.Coordinates
Assembly:  AGI.Foundation.Core (in AGI.Foundation.Core.dll) Version: 19.1.398.0 (19.1.398.0)
public UnitQuaternion(
	double[] elements,
	int startIndex


Type: SystemDouble
The array of coordinate values.
Type: SystemInt32
The index of the first element in the array to use.
ArgumentNullException Thrown when elements is .
ArgumentOutOfRangeException Thrown when an object of this type is constructed from an array with less than 4 elements.
For performance reasons, no checks or normalization procedures are performed when creating a UnitQuaternion from the given elements. The surrounding code is responsible for making sure that the given values represent a unit magnitude. To ensure proper normalization, create a Quaternion and then use the Normalize method to create a valid UnitQuaternion.
