## 3D Stage `Pacem3DElement` is the stage element for _3D drawings_. It must be associated with a `Pacem3DAdapterElement` in order to work, since it is agnostic about the rendering process. > Right now, focus is on this **WebGPU**-based adapter. > (ThreeJS-based implementation is being deprecated.) The _elements_ set dresses the five Platonic solids with physically-based materials (metalness/roughness, glTF-style): ``, and ` ` for the transmissive glass. fire glows (emissive map), air is glass that refracts what lies behind it (transmission, index of refraction and thickness), earth is worn, rusted painted metal (albedo, occlusion/roughness/metalness and normal maps, from [freepbr.com](https://freepbr.com/product/worn-rusted-painted-pbr/)), water ripples (normal map) and ether is a foggy aurora borealis. The scene is lit by an _environment_ light (image-based lighting): an HDR sky panorama ([Autumn Field Pure Sky](https://polyhaven.com/a/autumn_field_puresky), Poly Haven, CC0) lights every surface from all directions and shows in the reflections, sharp on smooth surfaces and blurred on rough ones.
