The SoNormalBinding class is a node for specifying normal vector bindings.
Use nodes of this type to specify how to map normal vectors from SoNormal nodes in the scene graph to shape nodes.
FILE FORMAT/DEFAULTS:
Enumeration of available types of mappings. See documentation of SoMaterialBinding node for explanation of the different values.
Note that SoNormalBinding::DEFAULT and SoNormalBinding::NONE has been obsoleted and are both mapped to SoNormalBinding::PER_VERTEX_INDEXED.

Destructor.
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:
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.
Implements SoBase.

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL
.
Reimplemented from SoFieldContainer.
This function performs the typical operation of a node for any action.
Reimplemented from SoNode.

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 SoNode.
References doAction().
|
virtual |
Action method for SoCallbackAction.
Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.
Reimplemented from SoNode.
References doAction().
|
virtual |
Action method for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
References doAction().
|
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 SoNode.
References doAction().
This method is mainly intended for internal use during file import operations.
It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistant representation of an instance of this class type.
TRUE
or FALSE
is returned, depending on if the instantiation and configuration of the new object of this class type went ok or not. The import process should be robust and handle corrupted input streams by returning FALSE
.
flags is used internally during binary import when reading user extension nodes, group nodes or engines.
Reimplemented from SoNode.
References SoNode::readInstance(), and value.
SoSFEnum SoNormalBinding::value |
The normal binding to use for subsequent shape nodes in the scene graph.
