* Mesh Distance Node *
The Mesh Distance node renders the distance from the pixel in the mesh to a geometric entity in the 3D space. There are 4 geometric entities defined by points: Point, Line, Segment and Plane. The distance is rendered as a monochromatic value defined by the minimum distance (black) and the range (white).

Method
Defines the geometric entity.
to point a: Distance from the pixel in the mesh to the Point A.
to point b: Distance from the pixel in the mesh to the Point B.
to line: Distance from the pixel in the mesh to the line defined by points A and B.
to segment: Distance from the pixel in the mesh to the line segment defined by points A and B.
to plane: Distance from the pixel in the mesh to the plane defined by point A and the normal B - A.
Point A X The x coordinate of Point A.
Point A Y The y coordinate of Point A.
Point A Z The z coordinate of Point A.
Point B X The x coordinate of Point B.
Point B Y The y coordinate of Point B.
Point B Z The y coordinate of Point B.
Radius Defines the minimum value. Any pixel with a distance to the entity lower than the radius will be rendered black.
Falloff Defines the maximum value as radius + falloff. Any pixel with a distance to the entity higher than the radius plus the falloff value will be rendered black.
The following examples were rendered using a 200 x 200 Plane model, and two points at A (-50,-50,0) and B (50, 50, 0).
