originVertex: Type: Cognex.VisionPro3D Cog3DVect3
The origin vertex of the rectangle.

xVector: Type: Cognex.VisionPro3D Cog3DVect3
The extent X vector of the rectangle.

yVector: Type: Cognex.VisionPro3D Cog3DVect3
The extent Y vector of the rectangle.

Exceptions

Exception	Condition
ArgumentException	If xVector or yVector is (0,0,0), or xVector and yVector are parallel.

Remarks

Notes:

If yVector is not perpendicular to xVector internally a new yVector is generated as follows and used instead:
- Create a plane with normal direction of xVector;
- Project yVector to this plane, and get the projected vector yVectorInternal;
- Scale yVectorInternal to have the same length as yVector.
Otherwise, yVectorInternal = yVector.
Size.X will be xVector.Length, and Size().Y will be yVector.Length.
Center will be originVertex + (xVector + yVectorInternal)/2
