Polyliner

Adds 3D line/ribbon mesh capabilities. Supports Godot 4.1.

Usage

The included LinePath3D node uses the Path3D node as a source of line segments; you can use it to easily make a smooth line.

The included Line3D node more or less behaves like the stock Line2D. Push your line points to it and a line mesh will be automatically generated.

The included Trail3D node forms a trail. This node will form line segments from its previous positions. It works in global space, so it works as a child of another Node3D.

These nodes render lines in the same manner, and all support the same shaders.

Within addons/godot-polyliner/shaders/ is a bunch of ready-made line shaders, from a cylinder facsimile to a full raymarched metal chain or swirling rope, and from a blooming light tube to a swooshing effect.

(don't forget to make your shaders unique before editing them!)
