Integrate Debug Draw 3D into Redot or add a similar feature.

[Ahem-008]

Describe the project you are working on

Making 3D games.

Describe the problem or limitation you are having in your project

Currently there are no easy way to draw lines and shapes in 3D except for a addon called "Debug Draw 3D".

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

By integrating Debug Draw 3D addon into the engine or adding a similar feature!

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

func _process(delta: float) -> void:
    var _time = Time.get_ticks_msec() / 1000.0
    var box_pos = Vector3(0, sin(_time * 4), 0)
    var line_begin = Vector3(-1, sin(_time * 4), 0)
    var line_end = Vector3(1, cos(_time * 4), 0)

    DebugDraw3D.draw_box(box_pos, Vector3(1, 2, 1), Color(0, 1, 0))
    DebugDraw3D.draw_line(line_begin, line_end, Color(1, 1, 0))
    DebugDraw2D.set_text("Time", _time)
    DebugDraw2D.set_text("Frames drawn", Engine.get_frames_drawn())
    DebugDraw2D.set_text("FPS", Engine.get_frames_per_second())
    DebugDraw2D.set_text("delta", delta)

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

This feature will be frequently used for testing, debugging and visualizing in 3D. It cannot be worked around with a few lines of script without using a addon.

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

This is an important and basic feature that should be available to users by default.

Would it be possible to expand this into something like Freya Holmer's Shapes addon for Unity or 3b1b's Manim?

I think having tools like that baked into the core would open up a lot of possibilities for procedural animations and dynamic visuals. For example, upgrading a title screen with rippling geometric patterns or creating visual demos to explain how code works.

Does this seem like something worth exploring here, or do you think it would make more sense as a separate idea? Either way, I think this kind of feature would be a huge boost for the engine
