.nodeTypes. Circle2D

The Circle2D node specifies a circle centred at (0,0) in the local 2D coordinate system.

HTML Encoding and Default Values

<Circle2D ccw='true' lit='true' metadata='X3DMetadataObject' radius='1' solid='true' useGeoCache='true' ></Circle2D>




Constructor for Circle2D

Name Type Argument Default Description
ctx Object <optional>
null context object, containing initial settings like namespace


These are the X3D / X3DOM fields of this node. Values should usually be received / set as strings via DOM functions (i.e., using setAttribute("myFieldName", "myFieldValue") and getAttribute("myFieldName")).
Name Type Default Value Range Inheritance Standard Description
ccw SFBool true X3DGeometryNode The ccw field defines the ordering of the vertex coordinates of the geometry with respect to user-given or automatically generated normal vectors used in the lighting model equations.
lit SFBool true X3DGeometryNode Specifies whether this geometry should be rendered with or without lighting.
metadata SFNode X3DMetadataObject X3DNode Field to add metadata information
radius SFFloat 1 (0, inf) The radius field specifies the radius of the Circle2D. The value of radius shall be greater than zero.
solid SFBool true X3DGeometryNode Specifies whether backface-culling is used. If solid is TRUE only front-faces are drawn.
useGeoCache SFBool true X3DGeometryNode Most geo primitives use geo cache and others might later on, but one should be able to disable cache per geometry node. Defaults to global useGeoCache setting parameter.
