This group covers what surfaces are made of: stylized finishes, physically based metal, glass, subsurface, thin film, and the map set that varies any of them per pixel.
| Sketch | What it shows |
| --- | --- |
| [Materials](materials.md) | The material library. One orbiting sphere grid shows each built-in `Material` (`.iridescent`/`.soapBubble`/`.velvet`/`.jade`/`.toon`/`.gooch`/…), and the view-angle finishes shift as it turns. |
| [Inked](inked.md) | The cartoon look: toon solids with an ink line around every shape (`outline(width:color:)`), under a three-point rig that follows the camera (`relativeTo(.camera)`), a world sun, or a `headlight()`, switched by a parameter. |
| [PhysicalMaterials](physicalmaterials.md) | The physically-based finish as a metallic × roughness sweep. `Material.physicallyBased` shades one sphere grid from tight mirror highlights to matte, and from dielectric to metal. |
| [Matcap](matcap.md) | Matcaps. A whole surface-and-lighting look is baked into one sphere texture and sampled by the view normal (`matcap(_:)`). That gives chrome, clay, wax, or a cel look with no scene lights at all. |
| [Explorer](explorer.md) | The material explorer. Every finish is shown on one shape, with its parameters to adjust. |
| [SurfaceMaps](surfacemaps.md) | The rest of the surface-map set: metallic-roughness, occlusion, and emissive maps, each varying a finish per pixel. |
| [NormalMaps](normalmaps.md) | Normal maps: per-pixel surface relief without per-pixel geometry. |
| [Detail](detail.md) | Detail maps: texture that stays sharp under a close look. |
| [Parallax](parallax.md) | A photographed stone wall read two ways: parallax occlusion and real displacement. |
| [Triplanar](triplanar.md) | Talavera tilework on meshes with no uvs at all, projected from three directions. |
| [Decals](decals.md) | Pictures stamped onto the scene, projected rather than mapped. |
| [Glass](glass.md) | Physically-based transmission and refraction. |
| [SeeThrough](seethrough.md) | The scene showing through glass, with no ray tracing. |
| [LiveSurface](livesurface.md) | The camera frame wraps a globe and lights it, so a live feed serves as a surface. |
| [CoatAndCloth](coatandcloth.md) | Clearcoat and sheen, the two layered finishes on the physically-based material. |
| [Subsurface](subsurface.md) | Light that travels under the surface before it comes back out. |
| [BrushedMetal](brushedmetal.md) | Anisotropic specular: brushed, turned, and satin finishes whose highlight is a streak instead of a dot. |
| [ThinFilm](thinfilm.md) | Thin-film interference two ways: a series of nm thicknesses on a physically-based surface, and animated soap bubbles on thin glass. |
