x3dom.nodeTypes. IndexedTriangleSet

IndexedTriangleSet is a geometry node that can contain a Color, Coordinate, Normal and TextureCoordinate node. Hint: insert a Shape node before adding geometry or Appearance. You can also substitute a type-matched ProtoInstance for content.

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
attrib MFNode X3DVertexAttributeNode X3DComposedGeometryNode If the attrib field is not empty it shall contain a list of per-vertex attribute information for programmable shaders.
ccw SFBool true X3DComposedGeometryNode 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.
color SFNode X3DColorNode X3DComposedGeometryNode If the color field is NULL, the geometry shall be rendered normally using the Material and texture defined in the Appearance node.
colorPerVertex SFBool true X3DComposedGeometryNode If colorPerVertex is FALSE, colours are applied to each face. If colorPerVertex is true, colours are applied to each vertex.
coord SFNode X3DCoordinateNode X3DComposedGeometryNode Contains a Coordinate node.
index MFInt32 [] [0, inf] index specifies triangles by connecting Coordinate vertices.
lit SFBool true X3DComposedGeometryNode Specifies whether this geometry should be rendered with or without lighting.
metadata SFNode X3DMetadataObject X3DComposedGeometryNode Field to add metadata information
normal SFNode Normal X3DComposedGeometryNode If the normal field is not NULL, it shall contain a Normal node whose normals are applied to the vertices or faces of the X3DComposedGeometryNode in a manner exactly equivalent to that described above for applying colours to vertices/faces (where normalPerVertex corresponds to colorPerVertex and normalIndex corresponds to colorIndex). If the normal field is NULL, the browser shall automatically generate normals in accordance with the node's definition. If the node does not define a behaviour, the default is to generate an averaged normal for all faces that share that vertex.
normalPerVertex SFBool true X3DComposedGeometryNode If normalPerVertex is FALSE, normals are applied to each face. If normalPerVertex is true, normals are applied to each vertex.
normalUpdateMode SFString 'fast' X3DComposedGeometryNode
solid SFBool true X3DComposedGeometryNode Specifies whether backface-culling is used. If solid is TRUE only front-faces are drawn.
texCoord SFNode X3DTextureCoordinateNode X3DComposedGeometryNode If the texCoord field is not NULL, it shall contain a TextureCoordinate node.
useGeoCache SFBool true X3DComposedGeometryNode Most geo primitives use geo cache and others might later on, but one should be able to disable cache per geometry node.
