CZML document-level clock controlling the viewer's timeline: start/stop interval, current time, playback multiplier, and looping behavior. Use when the intent mentions a clock, timeline, playback speed, looping, or specific start/stop times for the whole scene.
CZML corridors — fixed-width strips or roads that follow a centerline path along the ground or at altitude, with configurable corner styles. Use when the intent describes a corridor, road, fixed-width strip along a route, or a path with rounded, mitered, or beveled corners.
CZML custom/arbitrary entity properties for domain-specific data like population, fuel level, or sensor readings that aren't a standard graphics property, optionally time-varying or split across multiple sequential packets. Use when the intent describes a custom property, custom data field, or a named value attached…
CZML cylinders and cones for towers, sensor volumes, or tapered 3D shapes. Use when the intent describes a cylinder, cone, tapered column, tower, or truncated-cone shape, with a top radius, bottom radius, and length.
CZML distance-based scaling and visibility for billboards, points, labels, or models that should shrink/grow or show/hide based on camera distance. Use when the intent describes scaling by distance, near/far scale, or only showing an entity within a certain camera distance.
CZML filled ellipses and circles on or above the ground. Use when the intent describes a circle, ellipse, oval, or round shape defined by a radius or semi-major/semi-minor axes, optionally rotated or extruded.
CZML ellipsoids and spheres for domes, planetary bodies, or radius-based 3D round volumes. Use when the intent describes a sphere, ellipsoid, dome, or 3D round volume defined by radii, including wireframe-only variants.
CZML 3D models (glTF) for vehicles, aircraft, spacecraft, or any 3D asset placed on the globe, including per-node transformations and Model Articulations for jointed or moving parts. Use when the intent describes a 3D model, glTF asset, vehicle/aircraft/rocket model, or a model with moving, articulated, or transformed…
CZML entity orientation as unit quaternions, both a single fixed orientation and orientation sampled over time. Use when the intent describes an entity's heading, facing direction, attitude, 3D rotation, or orientation that changes over time.
CZML filled polygons and polygon regions, areas of interest, footprints, and closed shapes on the ground. Use when the intent describes a polygon, area, region, zone, footprint, or filled shape bounded by several corner points.
CZML polyline volumes — a 2D cross-section shape extruded along a 3D path, giving a line real thickness and volume instead of being infinitely thin. Use when the intent describes a polyline volume, thick line, extruded tube, or a cross-section swept along a path.
CZML static polyline and polylines for flight routes, boundaries, and fixed lines connecting two or more locations. Use when the intent describes a polyline, straight or multi-segment line, route, boundary, or connection between fixed points (not a moving entity).
CZML ground rectangles defined by west/south/east/north bounds, plus RGBA (0-255) vs RGBAF (0-1) color formats and striped materials. Use when the intent describes a rectangle, bounding box on the ground, striped fill, or specifies colors using integer RGBA or floating-point RGBAF components.
CZML reference properties that link one entity's property to another entity's value, including a single reference, an array of references (e.g. building a polygon's corners from other entities' positions), and referencing non-position properties like colors or materials. Use when the intent describes an entity that…
CZML time-dynamic motion: interpolated/sampled positions over an epoch and trails for orbiting, flying, or otherwise moving entities. Use when the intent describes an entity moving, orbiting, flying, or changing position over time (not a single static point).
CZML walls — vertical surfaces that follow a ground path, with optional per-point minimum/maximum heights. Use when the intent describes a wall, vertical barrier, fence-like surface, or a shape whose top/bottom edge follows a path of varying heights.
