Use when converting between coordinate systems, computing positions on the ellipsoid, performing spatial intersection tests, building model matrices, or working with geographic projections.\"\n---\n# CesiumJS Spatial Math & Transforms\n\nVersion baseline: CesiumJS v1.143 (2026-07-01)\n\nMathematical foundation for every CesiumJS application: coordinate types, unit conversions, ellipsoid geometry, reference frame transforms, bounding volumes, intersection tests, and projections.\n\n## Core Concepts\n\nCesiumJS uses a right-handed Earth-Centered Earth-Fixed (ECEF) coordinate system:\n\n- **Cartesian3** -- ECEF (x, y, z) in meters. Internal representation for all 3D positions.\n- **Cartographic** -- (longitude, latitude, height). Angles are **radians**, height in meters above ellipsoid.\n\nAll angular values in core math are radians. Use `Math.toRadians()` / `Math.toDegrees()`. Math types use a **static-method-with-result** pattern: pass a `result` parameter to reuse allocations.\n\n## Cartesian3 -- Positions and Vectors\n\n```js\nimport { Cartesian3, Math as CesiumMath } from \"cesium\";\n\n// From lon/lat degrees -- most common entry point\nconst pos = Cartesian3.fromDegrees(-105.0, 40.0);\nconst elevated = Cartesian3.fromDegrees(-105.0, 40.0, 1500.0); // with height\n\n// Batch creation: [lon, lat, lon, lat, ...]\nconst ring = Cartesian3.fromDegreesArray([-105, 40, -100, 40, -100, 35]);\n\n// With heights: [lon, lat, h, lon, lat, h, ...]\nconst wall = Cartesian3.fromDegreesArrayHeights([-105, 40, 500, -100, 40, 1000]);\n\n// From raw ECEF or from radians\nconst raw = new Cartesian3(-1275096.0, -4797180.0, 4075270.0);\nconst fromRad = Cartesian3.fromRadians(-1.8326, 0.6981, 1500.0);\n\n// Constants\nCartesian3.ZERO;   // (0,0,0)\nCartesian3.UNIT_X; // (1,0,0)\nCartesian3.UNIT_Y; // (0,1,0)\nCartesian3.UNIT_Z; // (0,0,1)\n```\n\n> **Breaking change (1.139, #8359):** `Cartesian2`, `Cartesian3`, and `Cartesian4`\n> are now ES6 classes. Calling `new` on a static **factory** method now throws --\n> `new Cartesian3.fromArray([...])` and `new Cartesian3.fromDegrees(...)` are\n> errors. Drop `new` for factory methods (`Cartesian3.fromArray([...])`); keep it\n> only for the real constructor (`new Cartesian3(x, y, z)`). More classes are\n> migrating to ES6 classes, so apply this rule everywhere.\n\n### Vector Operations\n\n```js\nconst a = new Cartesian3(1.0, 2.0, 3.0);\nconst b = new Cartesian3(4.0, 5.0, 6.0);\nconst r = new Cartesian3(); // reusable scratch\n\nCartesian3.add(a, b, r);                // a + b\nCartesian3.subtract(a, b, r);           // a - b\nCartesian3.multiplyByScalar(a, 2.0, r); // a * 2\nCartesian3.negate(a, r);                // -a\nCartesian3.cross(a, b, r);              // cross product\nCartesian3.normalize(a, r);             // unit vector\nCartesian3.lerp(a, b, 0.5, r);         // linear interpolation\nCartesian3.midpoint(a, b, r);           // midpoint\n\nconst dot = Cartesian3.dot(a, b);       // dot product\nconst len = Cartesian3.magnitude(a);    // ||a||\nconst dist = Cartesian3.distance(a, b); // Euclidean distance\nconst distSq = Cartesian3.distanceSquared(a, b); // faster for comparisons\nconst angle = Cartesian3.angleBetween(a, b);     // radians\n```\n\n## Cartographic -- Geographic Coordinates\n\n```js\nimport { Cartographic, Cartesian3, Math as CesiumMath } from \"cesium\";\n\nconst carto = Cartographic.fromDegrees(-105.0, 40.0, 1500.0);\nconst cartoRad = Cartographic.fromRadians(-1.8326, 0.6981, 1500.0);\n\n// Cartesian3 <-> Cartographic\nconst position = Cartesian3.fromDegrees(-105.0, 40.0, 1500.0);\nconst geo = Cartographic.fromCartesian(position);\nconst lonDeg = CesiumMath.toDegrees(geo.longitude); // -105.0\nconst latDeg = CesiumMath.toDegrees(geo.latitude);  // 40.0\nconst backToCart = Cartographic.toCartesian(geo);\n```\n\n## CesiumMath Utilities\n\n```js\nimport { Math as CesiumMath } from \"cesium\";\n\n// Degree/radian conversion\nconst rad = CesiumMath.toRadians(90.0);    // PI/2\nconst deg = CesiumMath.toDegrees(Math.PI); // 180\n\n// Constants: PI, TWO_PI, PI_OVER_TWO, PI_OVER_FOUR, RADIANS_PER_DEGREE\n// EPSILON1 (0.1) through EPSILON21 (1e-21)\n\nconst clamped = CesiumMath.clamp(value, 0.0, 1.0);\nconst interp = CesiumMath.lerp(0.0, 100.0, 0.5);          // 50\nconst norm = CesiumMath.negativePiToPi(angle);              // [-PI, PI]\nconst pos = CesiumMath.zeroToTwoPi(angle);                  // [0, 2*PI]\nconst safeLon = CesiumMath.convertLongitudeRange(angle);    // [-PI, PI)\nconst eq = CesiumMath.equalsEpsilon(a, b, CesiumMath.EPSILON7); // float compare\n```\n\n## Ellipsoid\n\n```js\nimport { Ellipsoid, Cartesian3, Cartographic } from \"cesium\";\n\n// Built-in ellipsoids\nEllipsoid.WGS84;       // Earth (default)\nEllipsoid.UNIT_SPHERE;  // radius 1\nEllipsoid.MOON;         // lunar sphere\nEllipsoid.MARS;         // Mars (v1.133+)\n\n// Change default (affects Ellipsoid.default everywhere)\nEllipsoid.default = Ellipsoid.MOON;\n\n// Conversions on a specific ellipsoid\nconst cart = Ellipsoid.WGS84.cartographicToCartesian(\n  Cartographic.fromDegrees(-75.0, 40.0, 100.0),\n);\nconst carto = Ellipsoid.WGS84.cartesianToCartographic(cart);\n\n// Surface normal at a position\nconst normal = Ellipsoid.WGS84.geodeticSurfaceNormal(cart, new Cartesian3());\n\n// Project point onto ellipsoid surface\nconst onSurface = Ellipsoid.WGS84.scaleToGeodeticSurface(cart, new Cartesian3());\n```\n\n## Transforms -- Reference Frames\n\n`Transforms` builds 4x4 matrices relating local frames to ECEF. The most commonly used function is `eastNorthUpToFixedFrame`.\n\n### East-North-Up (ENU)\n\nENU: X = east, Y = north, Z = up. Standard frame for placing models on the globe.\n\n```js\nimport { Cartesian3, Transforms, Matrix4 } from \"cesium\";\n\nconst origin = Cartesian3.fromDegrees(-105.0, 40.0);\nconst enuMatrix = Transforms.eastNorthUpToFixedFrame(origin);\n// Columns: [east, north, up, origin] in ECEF\n```\n\n### Heading-Pitch-Roll Model Matrix\n\nStandard way to position and orient a 3D model.\n\n```js\nimport { Cartesian3, Transforms, HeadingPitchRoll, Math as CesiumMath } from \"cesium\";\n\nconst position = Cartesian3.fromDegrees(-105.0, 40.0, 0.0);\nconst hpr = new HeadingPitchRoll(\n  CesiumMath.toRadians(90.0), // heading: 90 deg east\n  0.0,                         // pitch: level\n  0.0,                         // roll: none\n);\nconst modelMatrix = Transforms.headingPitchRollToFixedFrame(position, hpr);\n\n// Just the orientation quaternion (e.g., for Entity.orientation)\nconst orientation = Transforms.headingPitchRollQuaternion(position, hpr);\n```\n\n### HeadingPitchRoll\n\nHeading = rotation about -Z (compass bearing, clockwise). Pitch = about -Y. Roll = about +X. Radians.\n\n```js\nimport { HeadingPitchRoll, Math as CesiumMath } from \"cesium\";\nconst hpr = new HeadingPitchRoll(CesiumMath.toRadians(45.0), CesiumMath.toRadians(-10.0), 0.0);\nconst hprDeg = HeadingPitchRoll.fromDegrees(45.0, -10.0, 0.0); // convenience\n```\n\n### Other Local Frames\n\n```js\nimport { Transforms, Cartesian3 } from \"cesium\";\nconst origin = Cartesian3.fromDegrees(-105.0, 40.0);\n\nTransforms.northEastDownToFixedFrame(origin);  // NED (aviation)\nTransforms.northUpEastToFixedFrame(origin);     // NUE\n\n// Custom frame from any combo of east|north|up|west|south|down\nconst customFn = Transforms.localFrameToFixedFrameGenerator(\"north\", \"west\");\nconst matrix = customFn(origin);\n\n// Recover heading/pitch/roll from an existing model matrix\nconst hpr = Transforms.fixedFrameToHeadingPitchRoll(modelMatrix);\n```\n\n## Matrix4 -- 4x4 Transforms\n\nColumn-major storage (WebGL convention). Constructor takes row-major for readability.\n\n```js\nimport { Matrix4, Matrix3, Cartesian3, Quaternion } from \"cesium\";\n\n// Factory methods\nMatrix4.fromTranslation(new Cartesian3(10, 20, 30));\nMatrix4.fromRotationTranslation(Matrix3.fromRotationZ(Math.PI / 4), new Cartesian3(100, 0, 0));\nMatrix4.fromTranslationQuaternionRotationScale(\n  new Cartesian3(0, 0, 0), Quaternion.IDENTITY, new Cartesian3(2, 2, 2),\n);\nMatrix4.fromUniformScale(5.0);\n\n// Combine, transform, invert\nconst combined = Matrix4.multiply(matA, matB, new Matrix4());\nconst worldPt = Matrix4.multiplyByPoint(enuMatrix, new Cartesian3(100, 0, 0), new Cartesian3());\nconst inv = Matrix4.inverseTransformation(enuMatrix, new Matrix4()); // rigid-body only\n\n// Decompose\nMatrix4.getTranslation(enuMatrix, new Cartesian3());\nMatrix4.getMatrix3(enuMatrix, new Matrix3());\nMatrix4.getScale(enuMatrix, new Cartesian3());\n```\n\n## Quaternion -- Rotation\n\n```js\nimport { Quaternion, Cartesian3, HeadingPitchRoll, Math as CesiumMath, Matrix3 } from \"cesium\";\n\nQuaternion.IDENTITY; // (0, 0, 0, 1)\nconst q1 = Quaternion.fromAxisAngle(Cartesian3.UNIT_Z, CesiumMath.toRadians(45.0));\nconst q2 = Quaternion.fromHeadingPitchRoll(new HeadingPitchRoll(CesiumMath.toRadians(90), 0, 0));\nconst q3 = Quaternion.fromRotationMatrix(Matrix3.fromRotationZ(Math.PI / 2));\nconst mid = Quaternion.slerp(q1, q2, 0.5, new Quaternion());       // interpolate\nconst composed = Quaternion.multiply(q1, q2, new Quaternion());     // compose\n```\n\n## Geodesic Distance\n\n```js\nimport { Cartographic, EllipsoidGeodesic, Cartesian3 } from \"cesium\";\n\n// Surface distance (great-circle via Vincenty)\nconst geodesic = new EllipsoidGeodesic(\n  Cartographic.fromDegrees(-73.985, 40.758),  // New York\n  Cartographic.fromDegrees(-0.1276, 51.5074), // London\n);\nconst surfaceDist = geodesic.surfaceDistance;              // ~5,570 km\nconst midCarto = geodesic.interpolateUsingFraction(0.5);  // midpoint on surface\n\n// Chord (straight-line) distance\nconst chord = Cartesian3.distance(Cartesian3.fromDegrees(-105, 40), Cartesian3.fromDegrees(-104, 40));\n```\n\n## BoundingSphere\n\n```js\nimport { BoundingSphere, Cartesian3 } from \"cesium\";\n\nconst sphere = BoundingSphere.fromPoints(\n  Cartesian3.fromDegreesArray([-105, 40, -100, 40, -100, 35]),\n); // sphere.center (Cartesian3), sphere.radius (number)\n\nconst inside = Cartesian3.distance(sphere.center, Cartesian3.fromDegrees(-102, 37.5)) <= sphere.radius;\n```\n\n## Ray and Intersection Tests\n\n```js\nimport { Ray, IntersectionTests, Plane, Cartesian3, Ellipsoid } from \"cesium\";\n\nconst ray = new Ray(new Cartesian3(0, 0, 6378137), new Cartesian3(0, 0, -1)); // auto-normalized\nconst ptOnRay = Ray.getPoint(ray, 1000.0, new Cartesian3());\n\n// Ray-plane: returns Cartesian3 or undefined\nconst plane = Plane.fromPointNormal(Cartesian3.ZERO, Cartesian3.UNIT_Z);\nconst hit = IntersectionTests.rayPlane(ray, plane);\n\n// Ray-ellipsoid: returns Interval {start, stop} or undefined\nconst camRay = new Ray(new Cartesian3(0, 0, 20000000), new Cartesian3(0, 0, -1));\nconst interval = IntersectionTests.rayEllipsoid(camRay, Ellipsoid.WGS84);\nif (interval) {\n  const nearPt = Ray.getPoint(camRay, interval.start, new Cartesian3());\n}\n\n// Ray-triangle: returns parametric t or undefined\nconst t = IntersectionTests.rayTriangleParametric(ray, p0, p1, p2, true);\n```\n\n## SceneTransforms -- World to Screen\n\n```js\nimport { SceneTransforms, Cartesian3 } from \"cesium\";\n// World -> pixel coordinates (Cartesian2 or undefined if off-screen)\nconst winPos = SceneTransforms.worldToWindowCoordinates(viewer.scene, Cartesian3.fromDegrees(-105, 40));\n// High-DPI aware variant\nconst bufPos = SceneTransforms.worldToDrawingBufferCoordinates(viewer.scene, worldPos);\n```\n\n## Geographic Projections\n\n```js\nimport { GeographicProjection, WebMercatorProjection, Cartographic, Ellipsoid } from \"cesium\";\nconst carto = Cartographic.fromDegrees(-105.0, 40.0);\n\n// Plate Carree: project/unproject between Cartographic and Cartesian3\nconst geoProj = new GeographicProjection(Ellipsoid.WGS84);\nconst xy = geoProj.project(carto);           // Cartesian3\nconst back = geoProj.unproject(xy);          // Cartographic\n\n// Web Mercator (EPSG:3857)\nconst merc = new WebMercatorProjection(Ellipsoid.WGS84);\nconst mercXY = merc.project(carto);\n```\n\n## Common Patterns\n\n### Offset a Position in Local ENU\n\n```js\nimport { Cartesian3, Transforms, Matri","tagline":"CesiumJS spatial math - Cartesian3, Cartographic, Matrix4, Quaternion, Transforms, Ellipsoid, BoundingSphere, projections, coordinate conversions.
