xeokit Constants

---

The full enum vocabulary the SDK uses across modules — texture wrapping, mip filters, primitive types, encoding spaces, media types, projection modes, navigation modes, key codes, and more.

---

Constants live in one place so loaders, exporters, the renderer, and viewer wire-format all agree on the same integer codes. The GL ↔ xeokit mapping is handled inside the WebGL renderer; the external integer values exposed here are stable across SDK versions and form part of the wire format for XGF / DataModel payloads.

Categories

• Texture wrapping — RepeatWrapping, ClampToEdgeWrapping, MirroredRepeatWrapping.
• Texture filter — NearestFilter, LinearFilter, and the *MipMap* variants.
• Texture format / encoding — RGBAFormat, RGBA_S3TC_DXT*_Format, sRGBEncoding, LinearEncoding.
• Primitive types — TrianglesPrimitive, LinesPrimitive, PointsPrimitive, SolidPrimitive, SurfacePrimitive.
• Media types — PNGMediaType, JPEGMediaType, KTX2MediaType, etc.
• Projection / navigation — PerspectiveProjectionType, OrthoProjectionType, OrbitNavigationMode, etc.
• Key codes + layouts — KEY_A..KEY_Z, KEY_NUM_*, QWERTYLayout, AZERTYLayout.

Features

• Single source of truth — every SDK module reads constants from here; loaders / exporters / the renderer never disagree on a numeric code.
• Stable across versions — values are pinned and form part of the wire format. Reordering or renumbering breaks compatibility with persisted XGF / DataModel payloads.
• GL-mapped at the boundary — host code never passes raw GLenums; pass these constants and the renderer converts.
• Layout-aware key codes — QWERTYLayout / AZERTYLayout ship with the viewController defaults, plus the underlying KEY_* codes for custom maps.
