# Mesh Distance node

**Left Toolbar** > **3D Nodes** > ** 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).

## Procedure

### To create a Mesh Distance image:

Load one of more model in the Scene Window.

On the left toolbar choose 3D Nodes > Mesh Distance. >

Drag the Mesh Distance icon into the Node Graph.

Connect the output socket into the **Img** socket in the Mesh Distance node.

Adjust the attributes of the Mesh Distance node to modify it.

## Outputs

**Img**

A monochormatic image with the distance from the pixel to the 3D entity.

## Attributes Panel

**Position X**
Position X of the output image.

**Position Y**
Position Y of the output image.

**Size X**
Size X of the output image.

**Size Y**
Size Y of the output image.

**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.

## Samples

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).
