SoTextureCoordinateBinding(3)

NAME
SoTextureCoordinateBinding - The SoTextureCoordinateBinding class says how texture coordinates should be bound to shapes.

SoTextureCoordinateBinding binds current coordinates to subsequent shapes by using either per vertex or per indexed vertex binding.

Detailed Description

The SoTextureCoordinateBinding class says how texture coordinates should be bound to shapes.

SoTextureCoordinateBinding binds current coordinates to subsequent shapes by using either per vertex or per indexed vertex binding. FILE FORMAT/DEFAULTS:

TextureCoordinateBinding {
    value PER_VERTEX_INDEXED
}

Member Enumeration Documentation

  enum SoTextureCoordinateBinding::Binding
The binding types available for the SoTextureCoordinateBinding::value field.

Enumerator

PER_VERTEX
    Get a new texture coordinate from the pool of texture coordinates for each vertex of the shape.

Texture Coordinates are fetched from index 0 and onwards, incrementing the index into the texture coordinates pool by 1 for each new vertex of the shape node.

PER_VERTEX_INDEXED
    Get a new texture coordinate from the pool of texture coordinates for each vertex of the shape.

Texture coordinates are fetched by the index value settings of the shape.

DEFAULT
    Obsolete value, please don't use.

Constructor & Destructor Documentation

  SoTextureCoordinateBinding::SoTextureCoordinateBinding (void)
Constructor.

  SoTextureCoordinateBinding::~SoTextureCoordinateBinding () [protected], [virtual]
Destructor.

Member Function Documentation

  SoType SoTextureCoordinateBinding::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.

Implements SoBase.

  const SoFieldData * SoTextureCoordinateBinding::getFieldData (void) const [protected], [virtual]
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

  void SoTextureCoordinateBinding::doAction (SoAction * action) [virtual]
This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

  void SoTextureCoordinateBinding::callback (SoCallbackAction * action) [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.

  void SoTextureCoordinateBinding::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 SoNode.

  void SoTextureCoordinateBinding::pick (SoPickAction * action) [virtual]
Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

  SbBool SoTextureCoordinateBinding::readInstance (SoInput * in, unsigned short flags) [protected], [virtual]
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.

Member Data Documentation

  SoSFEnum SoTextureCoordinateBinding::value
Type of texturemap binding for subsequent shape nodes in the scenegraph. Default field value is SoTextureCoordinateBinding::PER_VERTEX_INDEXED.
