Add a Line3D node

[Manik2607]

Describe the project you are working on

A simple 3d game with bullet trails...

Describe the problem or limitation you are having in your project

I can't imagine there is still not a line 3d node in Godot ... Almost every game has some sort of lines it's really annoying to use addons for it... If there is line 2d there must be line 3d...

Describe the feature / enhancement and how it helps to overcome the problem or limitation

.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

.

If this enhancement will not be used often, can it be worked around with a few lines of script?

.

Is there a reason why this should be core and not an add-on in the asset library?

Because there is a line 2d node already...it causes confusion... every game needs it

Related to #3703.

@hackerManik3 Please answer all the proposal questions by editing your original post – these questions are not optional.

Remember that you can exploit CSGPolygon's Path mode to draw 3D lines, although animating them will be slow as the mesh needs to be regenerated every frame if you update the path.

Alternatively, you can use a MeshInstance with a CylinderMesh and stretch it as desired, but this only works for straight lines.

There's 3 repos on here that seem to add Line3D functionality, but I agree it should be on pairing with Line2D.

Here's one: https://github.com/RedefineGamedev/Line3D

Closing in favor of #6151, which is more detailed.
