This example demonstrates a camera calibration procedure for a checkerboard pattern, showing how snapshots are captured over time to compute the board’s position and orientation. The visualization uses an X3D ProtoDeclare to define the camera-calibration sensor, with fields for the board size (8 by 5 squares), snapshot count, and timing intervals. The rendering relies on X3D’s event system, exposing an `onStatus` output that reports calibration progress. The code specifies the calibration via VRML97-style exposed fields, making the sensor’s behavior explicit without relying on external JavaScript libraries.

This example visualizes a three-dimensional viewpoint model defined in X3D, showing how a virtual camera’s position, orientation, and field of view are structured. It renders the viewpoint as a geometric scene using the XSLT transformation in `gistfile1.xslt`, which parses the `<Viewpoint>` element and its attributes. The code relies on standard XML and XSLT processing to convert the viewpoint data into a visual representation, likely for interactive 3D exploration. The visualization highlights the default camera parameters, including position `(0 0 10)` and orientation, without simulating user navigation or animation.

This visualization demonstrates an MPEG AugmentationRegion proto-declaration, defining how augmented-reality content is anchored to a 2D region and tracked through translation and rotation fields. It shows the structural relationship between source data, provider identifiers, and 2D coordinates, with event outputs for changes in position, orientation, and error states. The example uses the XSLT file format to declare the proto, leveraging fields like `Vector2Array` and `Vector3Array` for spatial data, while enabling toggles via a Boolean `enabled` field. The rendering relies on the proto’s XML schema, not a specific charting library, focusing on the data model rather than visual output.

This example shows an interactive map prototype built with X3D, where users can pan, zoom, and switch between map providers and modes through a declarative ProtoDeclare interface. The map’s center and zoom level are exposed as event fields, while child nodes and overlays can be added or removed dynamically. The code relies on X3D’s event-in and exposedField mechanisms to handle user input and update the map’s GPS coordinates, making it a functional template for embedding tiled map navigation in a 3D scene graph.

This example visualizes the MPEG ReferenceSignalLocation prototypal declaration, showing how fields like source, referenceResources, detectionHints, and transformation values (translation, rotation) are structured within an XSLT-based prototypal schema. It renders the field definitions with their types and default values, using the VRML97 hints (exposedField, eventOut) to indicate data flow. The display lists each field name, its associated data type (e.g., Strings, Boolean, Vector3Array), and the default array values as literal text. The code relies on the XSLT transformation framework to parse the protoDeclare element, presenting the hierarchy without external JavaScript libraries.

This visualization maps the structure of X3D scene-graph definitions by rendering an XML schema as a network of nodes and links. It shows how complex types, elements, and attribute groups interconnect through references and inheritance. The code uses D3.js’s `forceSimulation` to compute node positions and SVG paths to draw links between schema components. Node sizes and colors encode type hierarchy, while the XSLT source file is parsed to extract these relationships. The rendering approach relies on standard SVG elements and D3’s data-binding to reflect the schema’s nested dependencies.

This visualization renders an X3D IndexedFaceSet schema definition as a structured diagram, showing the hierarchical relationships between the complexType and its child elements (color, coord, normal, texCoord) along with their attributes and default values. The code uses XSLT transformations to process the XML schema, likely converting it into a graphical node-and-link representation. It highlights the element declarations, attribute groups, and type definitions from the X3D specification, with the source data being the gistfile1.xslt file. The visualization emphasizes the schema’s structure, including optional attributes like ccw, solid, and coordIndex, without implying any interactive or dynamic behavior.

This example renders an X3D MovieTexture schema definition as a visual data-flow diagram. The XSLT file transforms XML schema markup into a structured graphic, likely using D3.js to map element and attribute nodes into a network layout with `d3.forceSimulation` for positioning. It visualizes the hierarchical relationship between the `MovieTexture` element and its attributes like `loop`, `speed`, and `url`, plus the associated `IS` child element. The rendering approach uses SVG paths and computed geometry, with styling inferred from the schema’s type definitions rather than raw data values.

This visualization shows the structure of an X3D skeletal animation system, displaying how a single bone node is defined with hierarchical children and a wide range of attributes. The code uses an XSLT stylesheet to transform XML definitions, leveraging XMTA custom types for 3D data such as vectors, rotations, and floating-point lists. It reveals the bone’s properties like translation, rotation, scale, and inverse kinematics limits, as well as skinning coordinates and weights. The rendering approach is not shown, but the data structure is explicit in the XSLT file.
