What is a Node?

A Node is a point that defines the path of a Tube.

By placing several nodes, you define where the Tube starts, where it changes direction and where it ends.

Nodes define the Tube shape

A Tube is built by connecting its nodes.

Depending on how those nodes are placed, the Tube can form:

• Straight lines
• Angled sections
• Curves

The visible path between nodes is rendered by NeonFX as part of the Tube.

Nodes can have handles

A node can also use Bézier handles.

These handles control the curve on either side of the node.

NeonFX does not automatically smooth nodes or create curved handles for them. A node remains straight until one of its visible handles is moved.

Nodes are edited visually

Nodes can be selected directly in the editor.

When you look at a node and select it, NeonFX exposes the controls needed to move or adjust it.

The following articles explain how to add, select and move nodes individually.
