Introduction
|
||
|
|
------------
|
||
|
|
|
||
|
|
In a project, there may be times when text needs to be created as
|
||
|
|
part of a 3D scene and not just in the HUD. Godot provides two
|
||
|
|
methods to do this. The Label3D node and the text mesh for a
|
||
|
|
MeshInstance node.
|
||
|
|
|
||
|
|
This page does **not** cover how to display a GUI scene in a 3D
|
||
|
|
environment. For information on how to do that see `this <https://github.com/godotengine/godot-demo-projects/tree/master/viewport/2d_in_3d>`__

Label3D
|

Label3D behaves like a label node but in a 3D space. Unlike label
|
||
|
|
node this can not inherit properties of a GUI theme. However its
|
||
|
|
look remains customizable and uses the same DynamicFont and BitmapFont
|
||
|
|
subresources control nodes use.
|
||
|
|
|
||
|
|
Label3D has minimal interaction with a 3D environment, it can be lit
|
||
|
|
up and shaded by light sources if the shaded flag is enabled, but it
|
||
|
|
will not cast a shadow, even with cast shadow turned on under the nodes
|
||
|
|
GeometryInstance3D settings. This is because the node is a quad mesh
|
||
|
|
(one glyph per quad) with transparent textures and has the same limitations
|
||
|
|
as Sprite3D. See :ref:`this page <doc_3d_rendering_limitations_transparency_sorting>`
|
||
|
|
for more information.

Text mesh
|

Text meshes have similarities to Label3D. They display text in a 3D
|
||
|
|
scene, and will use the same DynamicFont subresource. However text is 3D and
|
||
|
|
has the properties of a mesh. A text mesh cast shadows onto the environment
|
||
|
|
and can have a material applied to it. Here is an example of a texture and
|
||
|
|
how it's applied to the mesh.

|

|
|
There are two limitations to text mesh. It can't use bitmap fonts, or fonts
|
||
|
|
with self intersection.
