Detailed Description

The SoIndexedLineSet class is used to render and otherwise represent indexed lines.

The indexed counterpart of SoLineSet. Lines can specified using indices for coordinates, normals, materials and texture coordinates.

If no normals are supplied on the stack (or in the vertexProperty field), the lines will be rendered with lighting disabled.

For more information about line sets, see documentation in SoLineSet. For more information about indexed shapes, see documentation in SoIndexedShape and SoIndexedFaceSet.

Member Function Documentation

SoType SoIndexedLineSet::getTypeId ( void  ) const
virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting.

Usage example:

void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoIndexedShape.

const SoFieldData ** SoIndexedLineSet::getFieldDataPtr ( void  )
staticprotected

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Reimplemented from SoIndexedShape.

const SoFieldData * SoIndexedLineSet::getFieldData ( void  ) const
protectedvirtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoIndexedShape.

void SoIndexedLineSet::GLRender ( SoGLRenderAction action)
virtual

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.

Reimplemented from SoShape.

void SoIndexedLineSet::getBoundingBox ( SoGetBoundingBoxAction action)
virtual

Action method for the SoGetBoundingBoxAction.

Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.

Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change the relevant state variables.

Reimplemented from SoShape.

void SoIndexedLineSet::getPrimitiveCount ( SoGetPrimitiveCountAction action)
virtual

Action method for the SoGetPrimitiveCountAction.

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.

Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables.

Reimplemented from SoShape.

void SoIndexedLineSet::notify ( SoNotList l)
protectedvirtual

Notifies all auditors for this instance when changes are made.

Reimplemented from SoVertexShape.
