Shape

Overview

Shape can appear under any grouping node. Shape can contain an Appearance node and a geometry node (Box Cone Cylinder ElevationGrid Extrusion IndexedFaceSet IndexedLineSet LineSet PointSet Sphere Text).

The Shape node belongs to the Shape component and its default container field is children. It is available since X3D version 2.0 or later.

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.

SFBool [ ] visible TRUE

Whether or not renderable content within this node is visually displayed.

Hint

  • The visible field has no effect on animation behaviors, event passing or other non-visual characteristics.
  • Content must be visible to be collidable and to be pickable.

SFBool [ ] castShadow TRUE

castShadow defines whether this Shape casts shadows as produced by lighting nodes.

Hint

  • If the visible field is FALSE, then the Shape does not cast any shadows.
  • If prior X3D3 content is loaded into an X3D4 model, then legacy Shape nodes have shadows set to true.

SFBool [ ] bboxDisplay FALSE

Whether to display bounding box for associated geometry, aligned with world coordinates.

Hint

  • The bounding box is displayed regardless of whether contained content is visible.

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.

SFNode [in, out] appearance NULL [X3DAppearanceNode]

Input/Output field appearance.

SFNode [in, out] geometry NULL [X3DGeometryNode]

Input/Output field geometry.

Description

Hint

  • You can also substitute a type-matched ProtoInstance node for contained content.
