public abstract class SoIndexedShape extends SoVertexShape
SoIndexedShapedefines 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:
<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 or
Specific to the subclass.
One material per vertex.
When any _INDEXED binding is used for materials or normals, the
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.
This is an abstract class. See the reference page of a derived class for the format and default values.
