Materials

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	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	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	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	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	The material explorer. Every finish is shown on one shape, with its parameters to adjust.
SurfaceMaps	The rest of the surface-map set: metallic-roughness, occlusion, and emissive maps, each varying a finish per pixel.
NormalMaps	Normal maps: per-pixel surface relief without per-pixel geometry.
Detail	Detail maps: texture that stays sharp under a close look.
Parallax	A photographed stone wall read two ways: parallax occlusion and real displacement.
Triplanar	Talavera tilework on meshes with no uvs at all, projected from three directions.
Decals	Pictures stamped onto the scene, projected rather than mapped.
Glass	Physically-based transmission and refraction.
SeeThrough	The scene showing through glass, with no ray tracing.
LiveSurface	The camera frame wraps a globe and lights it, so a live feed serves as a surface.
CoatAndCloth	Clearcoat and sheen, the two layered finishes on the physically-based material.
Subsurface	Light that travels under the surface before it comes back out.
BrushedMetal	Anisotropic specular: brushed, turned, and satin finishes whose highlight is a streak instead of a dot.
ThinFilm	Thin-film interference two ways: a series of nm thicknesses on a physically-based surface, and animated soap bubbles on thin glass.
