Overview

Cylinder is a geometry node.

The Cylinder node belongs to the Geometry3D component and requires at least level 1, its default container field is geometry. It is available since VRML 2.0 and from X3D version 3.0 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

SFBool [in, out] top TRUE

Whether to draw top (inside faces are never drawn).

SFBool [in, out] side TRUE

Whether to draw sides (inside faces are never drawn).

SFBool [in, out] bottom TRUE

Whether to draw bottom (inside faces are never drawn).

SFFloat [ ] height 2 (0,∞)

Size in meters.

Hint

  • For size animation, modify the scale of a parent/ancestor Transform node instead.

Warning

  • Simple-geometry dimensions are initializeOnly and cannot be changed after initial creation, avoiding the need for potentially expensive tessellation at run time.

SFFloat [ ] radius 1 (0,∞)

Size in meters.

Hint

  • For size animation, modify the scale of a parent/ancestor Transform node instead.

Warning

  • Simple-geometry dimensions are initializeOnly and cannot be changed after initial creation, avoiding the need for potentially expensive tessellation at run time.

SFBool [ ] solid TRUE

Setting solid true means draw only one side of polygons (backface culling on), setting solid false means draw both sides of polygons (backface culling off).

Hints

  • Mnemonic “this geometry is solid like a brick” (you don’t render the inside of a brick).
  • If in doubt, use solid=’false’ for maximum visibility.
  • (X3D version 4.0 ISO.proof draft) accessType relaxed to inputOutput in order to support animation and visualization.

Warnings

  • Default value true can completely hide geometry if viewed from wrong side!
  • solid false not supported in VRML97.
