This is probably an insane question, but...

Are there any domain-specific languages out there for making 3D model assets? (Preferably supporting rigging and texturing in the language. Preferably FOSS and can output the assets as GLTF. But please share anything remotely in the direction of what I'm talking about.)

I'm thinking something along the lines of OpenSCAD, but more for art and game assets than CAD. Like a marriage of OpenSCAD's DSL-ness with Blender's suitability more for game assets and such.
