I just want to be able to see some text rendered in the world.

The only example code that I've found is this:

  GameObject Text = new GameObject();      
  TextMesh textMesh = Text.AddComponent<TextMesh>();
  textMesh.font = new Font();
  mat.SetColor("_Color", Color.black);
  mat.SetPass(0);       
  meshRenderer.material = mat;
  textMesh.text = "Hello World!";       

Where mat is defined by the code:

  Shader shader = Shader.Find("Hidden/Internal-Colored");
  mat = new Material(shader);
  mat.hideFlags = HideFlags.HideAndDontSave;     
  mat.SetInt("_Cull", (int)UnityEngine.Rendering.CullMode.Off);
  mat.SetInt("_ZWrite", 0);   
  mat.SetColor("_Color", Color.blue);
  mat.SetPass(0);       

This code is added to the Start of MonoBevaviour. And the script is tied to Game Main camera.

No text appears anywhere that I can see.

Ah I think I might have something.

I am not sure though if this works for VR devices - I know that Unity e.g. doesn't render Screenspace overlay canvas on XR.

But back to the point: There is a legacy UI system which is usually not used anymore except for in editor Inspector scripting IMGUI

I think it might actually fit your very special need using GUILayout.Label you should be able to draw a flat label onto the screen even in VR.

With GUI.Label you have full control over the pixel coordinates and size.

public class YourTextDrawer : MonoBehaviour
{
    void OnGUI() 
    {
        var color = GUI.color;
        GUI.color = Color.green;
        var textPosition = new Rect(Screen.width / 2 - 150, Screen.height / 2 - 100, 300, 200);
        GUI.Label(textPosition, "Hello World!");
        GUI.color = color;
    }
}

Not tested, just scrabbling this down from memory right now

And actually thinking about it, this might even work for your image as well

Just use TextMeshPro.

Right click to hierarchy -> 3D Object -> Text - TextMeshPro.

Then you will see a text appear in your scene. You can use that in 3D space.
