This node is the abstract base class for all vertex-based shapes that are constructed from indices, including OIV.Inventor.Nodes.SoIndexedFaceSet, OIV.Inventor.Nodes.SoIndexedTriangleStripSet, and OIV.Inventor.Nodes.SoIndexedLineSet. OIV.Inventor.Nodes.SoIndexedShape defines fields that are used in all of its subclasses.
All subclasses of OIV.Inventor.Nodes.SoNonIndexedShape construct objects by using the coordinates specified by the OIV.Inventor.Nodes.SoVertexShape.m_vertexProperty field (from OIV.Inventor.Nodes.SoVertexShape), or the current inherited coordinates. The OIV.Inventor.Nodes.SoIndexedShape.m_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, tangents or texture coordinates when the appropriate binding is PER_VERTEX_INDEXED.
Material, normal and tangent bindings are interpreted as follows for each subclass:
<TABLE border=0 cellspacing=0 cellpadding=5> <TR><TD valign=_top> OVERALL <TD valign=_top> One material for the entire shape. <TR><TD valign=_top> PER_PART <TD valign=_top> Specific to the subclass. <TR><TD valign=_top> PER_PART_INDEXED <TD valign=_top> Same as PER_PART, using indices from the #materialIndex,OIV.Inventor.Nodes.SoIndexedShape.m_normalIndex or OIV.Inventor.Nodes.SoIndexedShape.m_tangentIndex field.
PER_FACE
Specific to the subclass.
PER_FACE_INDEXED
Same as PER_FACE, using indices from the OIV.Inventor.Nodes.SoIndexedShape.m_materialIndex, OIV.Inventor.Nodes.SoIndexedShape.m_normalIndex or OIV.Inventor.Nodes.SoIndexedShape.m_tangentIndex field.
PER_VERTEX
One material per vertex.
PER_VERTEX_INDEXED
One material per vertex, using indices from the OIV.Inventor.Nodes.SoIndexedShape.m_materialIndex, OIV.Inventor.Nodes.SoIndexedShape.m_normalIndex or OIV.Inventor.Nodes.SoIndexedShape.m_tangentIndex field.
When any _INDEXED binding is used for materials, normals or tangents, the OIV.Inventor.Nodes.SoIndexedShape.m_materialIndex, OIV.Inventor.Nodes.SoIndexedShape.m_normalIndex or OIV.Inventor.Nodes.SoIndexedShape.m_tangentIndex field is used to determine the indices for the materials, normals or tangents. If this field contains a single value of -1 (the default), the coordinate indices from the OIV.Inventor.Nodes.SoIndexedShape.m_coordIndex field are used as well for materials, normals or tangents. When the binding is PER_VERTEX_INDEXED, indices in these fields that correspond to negative indices in OIV.Inventor.Nodes.SoIndexedShape.m_coordIndex are skipped; for other index bindings all the values in the fields are used, in order.
Explicit texture coordinates (as defined by OIV.Inventor.Nodes.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 OIV.Inventor.Nodes.SoIndexedShape.m_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 OIV.Inventor.Nodes.SoIndexedShape.m_coordIndex, OIV.Inventor.Nodes.SoIndexedShape.m_materialIndex, OIV.Inventor.Nodes.SoIndexedShape.m_normalIndex, OIV.Inventor.Nodes.SoIndexedShape.m_tangentIndex, and OIV.Inventor.Nodes.SoIndexedShape.m_textureCoordIndex fields are valid with respect to the current state, or errors will occur.
Limitations:
Due to limitations of the OpenGL VBO (vertex buffer object) rendering model, in general it is not possible to use VBO rendering (and performance may be lower) if either the normal binding, tangent binding or the material binding is set to either PER_PART(_INDEXED) or PER_FACE(_INDEXED). See individual derived classes for exceptions.
This is an abstract class. See the reference page of a derived class for the format and default values.
