Bitruvius SDK foundation: the domain-agnostic, geo-free base every Bitruvius SDK builds on (task/worker scheduling, runtime capability detection, request authorization, SDK config, and error types).

meshopt decoder seam for @bitruvius/gltf: decode-only meshoptimizer wasm (EXT_meshopt_compression), vendored self-contained

Bitruvius geospatial SDK core: decoder/renderer/viewer-adapter contracts, geospatial math (ENU/ECEF/mercator), map-style expressions, and the dequantization reference. Builds on @bitruvius/foundation.

Bitruvius raster visualization: colormaps, hillshade and 3D terrain rendering on WebGL2

Draco geometry decoder seam for the Bitruvius glTF, 3D Tiles and I3S pipelines: decode-only Google Draco wasm (KHR_draco_mesh_compression / 3DTILES_draco_point_compression), vendored and hardened

KTX2/Basis texture transcoder seam for @bitruvius/gltf: transcode-only Basis Universal wasm (KHR_texture_basisu), vendored and hardened

Bitruvius point-cloud renderer: RGB/intensity/classification LiDAR rendering on WebGL2

Bitruvius mesh renderer: raw-WebGL2 unlit-textured triangle/point rendering of OGC 3D-Tiles / I3S meshes (PackedMeshTile), in the shared ENU frame

Composed off-main-thread decoder for OGC 3D-Tiles textured meshes: wires @bitruvius/gltf + draco + meshopt + ktx2 into a worker-pooled MeshTileDecoder

Composed off-main-thread decoder for OGC 3D-Tiles point clouds (v1.0 .pnts + v1.1 glTF POINTS): wires @bitruvius/gltf + draco into a worker-pooled CesiumPointDecoder

Bitruvius SDK glTF 2.0 / GLB parser + OGC 3D-Tiles container handlers (b3dm/i3dm/cmpt/pnts): pure TS, no WebGL/DOM/codecs. Normalizes tile content to a GPU-ready struct-of-arrays mesh/point representation; geometry decompression and texture transcode are

Bitruvius point-symbol renderer: instanced icon/billboard quads (sprite atlas, screen-space sizing, RGBA8UI picking) for I3S Point-feature symbology, in the shared ENU frame

Bitruvius SDK geoid: compact EGM96 undulation grid and lookup, converting WGS84 ellipsoidal heights to orthometric (MSL) so global datasets seat on terrain without a hand-tuned geoidN

ArcGIS authentication for the Bitruvius SDK: OAuth 2.0 PKCE, Enterprise and federated servers, API keys and web-tier SSO for secured scene layers, I3S point clouds and elevation terrain. Opt-in, and zero bytes for public services.

Stream 3D Tiles and I3S services, lidar point clouds, Gaussian splats and elevation terrain into MapLibre GL JS

Bitruvius Gaussian-splat renderer: EWA splatting, spherical harmonics, depth-sorted WebGL2

Bitruvius SDK codec runtime: capability-gated decode-backend selection and WebAssembly loading

Bitruvius SDK WebGL2 render runtime: GL context, programs, buffers, data textures, blend and depth presets, splat depth sorting, and the shadow, clip and drape contracts every Bitruvius renderer shares

BVC decoder: the Bitruvius container for lidar point clouds and Gaussian splats, decoded in the browser via wasm

Bitruvius SDK pure 3D-Tiles streaming engine (gaussian splat, textured mesh, point cloud): codec- and renderer-agnostic traversal, cache, scheduler, and ENU packing (no WebGL/DOM/MapLibre)
