SoIndexedShape defines fields that are used in all of its subclasses. All subclasses of SoNonIndexedShape construct objects by using the coordinates specified by the vertexProperty field (from SoVertexShape), or the current inherited coordinates. The coordIndex field defined by this class contains the indices into the current coordinates of the vertices of the shape. These indices are also used for materials, normals, or texture coordinates when the appropriate binding is PER_VERTEX_INDEXED. Material and normal bindings are interpreted as follows for each subclass: OVERALL One material for the entire shape. PER_PART Specific to the subclass. PER_PART_INDEXED Same as PER_PART, using indices from the materialIndex or normalIndex field. PER_FACE Specific to the subclass. PER_FACE_INDEXED Same as PER_FACE, using indices from the materialIndex or normalIndex field. PER_VERTEX One material per vertex. PER_VERTEX_INDEXED One material per vertex, using indices from the materialIndex or normalIndex field. When any _INDEXED binding is used for materials or normals, the materialIndex or normalIndex field is used to determine the indices for the materials or normals. If this field contains a single value of -1 (the default), the coordinate indices from the coordIndex field are used as well for materials or normals. When the binding is PER_VERTEX_INDEXED, indices in these fields that correspond to negative indices in coordIndex are skipped; for other index bindings all the values in the fields are used, in order. Explicit texture coordinates (as defined by SoTextureCoordinate2) may be bound to vertices of an indexed shape consecutively (if the texture coordinate binding is PER_VERTEX) or by using the indices in the textureCoordIndex field (if the binding is PER_VERTEX_INDEXED). As with all vertex-based shapes, if there is a current texture but no texture coordinates are specified, a default texture coordinate mapping is calculated using the bounding box of the shape. Be sure that the indices contained in the coordIndex, materialIndex, normalIndex, and textureCoordIndex fields are valid with respect to the current state, or errors will occur. FIELDS SoMFInt32 coordIndex The indices of the coordinates that the shape uses as its vertices. The coordinates connect to form faces, lines, or other shapes. Each subclass defines special negative indices to use to indicate separation between faces, lines, and so on. SoMFInt32 materialIndex SoMFInt32 normalIndex SoMFInt32 textureCoordIndex The indices of the materials, normals, and texture coordinates that are used for the shape. These fields are used only when the appropriate binding is one of the _INDEXED bindings. By default, the values of these fields indicate that the coordinate indices should be used for materials, normals, or texture coordinates as well. FUNCTIONS SoType SoIndGetClassTypeId() Returns type identifier for this class. FILE FORMAT/DEFAULTS This is an abstract class.
