Detailed Description

An adapter that make a 2D noise from a 3D noise.

The 3D point is taken on a plane defined by a normal and a point. The 3D point has the same \( x \) and \( y \) coordinates as the 2D point, and the plane is used to determine the \( z \) coordinate.

By default, the \( z = 0 \) plane is used.
