See the X3D Specification, below.

VRML X3D SPECIFICATION

This section describes the expected behavior of the node in a conforming X3D browser application. In some cases, the application is responsible for implementing portions of the expected behavior. Open Inventor viewer classes and IVF classes implement some of the application behaviors.

This section may reference portions of the X3D specification that are not present in this help file. The complete X3D spec is available at http://www.web3d.org.

An SoVRMLTriangleFanSet represents a 3D shape composed of triangles that form a fan shape around the first vertex declared in each fan.

The fanCount field describes how many vertices are to be used in each fan from the coord field. Coordinates are assigned to each strip by taking fanCount[n] vertices from the coord field. Each value of the fanCount array must be greater than or equal to three. It is an error to have a value less than three.

The following figure displays a TriangleFanSet containing a single fan showing the ordering of the vertices for that fan.

The SoVRMLTriangleFanSet node is specified in the local coordinate system and is affected by the transformations of its ancestors. Descriptions of the color, coord, normal, and texCoord fields are provided in the Color, Coordinate, Normal, and TextureCoordinate nodes, respectively. If values are provided for the color, normal, and texCoord fields, there must be at least as many values as are present in the coord field. The value of the colorPerVertex field is ignored and always treated as true. If the normal field is not provided, for each fan, the normal will be generated as follows: if normalPerVertex is true, the normal will be the average of all triangles within that fan sharing that vertex. For the vertex of the fan, the normal will be the average of the contributions of all of the individual face normals. If normalPerVertex is false, the normal will be generated for the current triangle based on the ccw field.

The solid field determines whether the SoVRMLTriangleFanSet is visible when viewed from the inside.
