CADFace

Overview

CADFace holds geometry representing one face in a Computer-Aided Design (CAD) CADPart. CADFace can only contain a single Shape or LOD node (with containerField='shape').

The CADFace node belongs to the CADGeometry component and requires at least level 2, its default container field is children. It is available from X3D version 3.1 or higher.

Fields

SFNode [in, out] metadata NULL [X3DMetadataObject]

Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.

Hint

• X3D Architecture 7.2.4 Metadata

SFString [in, out] name “”

Optional name for this particular CAD node.

Hints

• Well-defined names can simplify design and debugging through improved author understanding.
• X3D Scene Authoring Hints, Naming Conventions

Warning

• name field is not included if this instance is a USE node, in order to avoid potential mismatches.

SFBool [in, out] visible TRUE

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

Hints

• 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 [in, out] 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.

Hints

• Can be useful for collision computations or inverse-kinematics (IK) engines.
• Precomputation and inclusion of bounding box information can speed up the initialization of large detailed models, with a corresponding cost of increased file size.
• X3D Architecture, 10.2.2 Bounding boxes
• X3D Architecture, 10.3.1 X3DBoundedObject

SFVec3f [ ] bboxCenter 0 0 0 (-∞,∞)

Bounding box center accompanies bboxSize and provides an optional hint for bounding box position offset from origin of local coordinate system.

Hints

• Precomputation and inclusion of bounding box information can speed up the initialization of large detailed models, with a corresponding cost of increased file size.
• X3D Architecture, 10.2.2 Bounding boxes
• X3D Architecture, 10.3.1 X3DBoundedObject

SFNode [in, out] shape NULL [X3DShapeNode, LOD, Transform]

Contained Shape for this CADPart.

Warning

• If LOD or Transform are used, only zero or one Shape child is allowed to be active at one time.

Advice

Hint

• X3D for Advanced Modeling (X3D4AM) slideset

Warnings

• Only zero or one Shape child is allowed to be active at one time.
• Requires X3D profile='Full' or else include <component name='CADGeometry' level='2'/>
