getUnitNormal Method

Return the unit normal for the plane.

• The abstract base class implementation assembles the normal from normalX, normalY, normalZ calls.
• Derived classes should (but are not required to) override for maximum efficiency if the separate normal calls cause repeated normalization.

getUnitNormal(result?: Vector3d): undefined | Vector3d
