➨ Fields

The Arc node specifies a linear circular arc whose center is at (0,0) and whose angles are measured starting at the positive x-axis and sweeping towards the positive y-axis.

Fields

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 Rendering/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.
endAngle SFFloat pi/2 [-2 pi, 2 pi] The arc extends from the startAngle counterclockwise to the endAngle.
endAngle SFFloat pi/2 [-2 pi, 2 pi] The arc extends from the startAngle counterclockwise to the endAngle.
lit SFBool true Rendering/X3DGeometryNode Specifies whether this geometry should be rendered with or without lighting.
metadata SFNode X3DMetadataObject Core/X3DNode Field to add metadata information
radius SFFloat 1 (0, inf) The radius field specifies the radius of the circle of which the arc is a portion.
solid SFBool true Rendering/X3DGeometryNode Specifies whether backface-culling is used. If solid is TRUE only front-faces are drawn.
startAngle SFFloat 0 [-2 pi, 2 pi] The arc extends from the startAngle counterclockwise to the endAngle.
startAngle SFFloat 0 [-2 pi, 2 pi] The arc extends from the startAngle counterclockwise to the endAngle.
subdivision SFFloat 32 Number of lines into which the arc is subdivided
subdivision SFFloat 32 Number of segments of the disc
subdivision SFFloat 32 Number of lines into which the arc is subdivided
subdivision SFFloat 32 Number of segments the circle is composed of
useGeoCache SFBool true Rendering/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.
