X3D Reference

GeoTransform

GeoTransform

GeoTransform is a Grouping node that can contain most nodes. GeoTransform translates, orients and scales GeoCoordinate geometry within the local world coordinate system. GeoTransform coordinate system X-Z plane is tangent to ellipsoid of local spatial reference frame.

The GeoTransform node belongs to the Geospatial component and its container field is children. It is available since X3D version 3.0 or later.

Hierarchy

Fields

SFNode [in, out] metadata NULL [X3DMetadataObject]

Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.

SFVec3f [in, out] translation 0 0 0 (-∞,∞)

Position (x, y, z in meters) of children relative to local coordinate system.

Hint

The order of operation is first apply the center offset, then scaleOrientation and scale, then rotation, then restore the center offset, then translation.

SFRotation [in, out] rotation 0 0 1 0 [-1,1] or (-∞,∞)

Orientation (axis, angle in radians) of children relative to local coordinate system.

Hint

The order of operation is first apply the center offset, then scaleOrientation and scale, then rotation, then restore the center offset, then translation.

SFVec3f [in, out] scale 1 1 1 (0,∞)

Non-uniform x-y-z scale of child coordinate system, adjusted by center and scaleOrientation.

Hint

The order of operation is first apply the center offset, then scaleOrientation and scale, then rotation, then restore the center offset, then translation.

SFRotation [in, out] scaleOrientation 0 0 1 0 [-1,1] or (-∞,∞)

Preliminary rotation of coordinate system before scaling (to allow scaling around arbitrary orientations).

Hint

The order of operation is first apply the center offset, then scaleOrientation and scale, then rotation, then restore the center offset, then translation.

SFNode [ ] geoOrigin NULL [GeoOrigin] (deprecated)

Field geoOrigin.

MFString [ ] geoSystem [ "GD", "WE" ]

Field geoSystem.

SFVec3d [in, out] geoCenter 0 0 0 (-∞,∞)

Input/Output field geoCenter.

SFVec3f [ ] bboxSize -1 -1 -1 [0,∞) or −1 −1 −1

Bounding box size is usually omitted, and can easily be calculated automatically by an X3D player at scene-loading time with minimal computational cost. Bounding box size can also be defined as an optional authoring hint that suggests an optimization or constraint.

Hint

Can be useful for collision computations or inverse-kinematics (IK) engines.

SFVec3f [ ] bboxCenter 0 0 0 (-∞,∞)

Bounding box center: optional hint for position offset from origin of local coordinate system.

MFNode [in] addChildren

Input field addChildren.

MFNode [in] removeChildren

Input field removeChildren.

MFNode [in, out] children [ ] [X3DChildNode]

Grouping nodes contain a list of children nodes.

Hint

Each grouping node defines a coordinate space for its children, relative to the coordinate space of its parent node. Thus transformations accumulate down the scene graph hierarchy.

Description

Hints

  • +Y axis is up.
  • Insert a Shape node before adding geometry or Appearance.
  • Include <component name='Geospatial' level='2'/>

Warning

  • Avoid having GeoLocation or GeoTransform as a parent of ancestor node, since multiple geospatial transformations then occur with unpredictable results.
