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.

SYNOPSIS

#include <Inventor/nodes/SoTextureCoordinateBinding.h>

Inherits SoNode.

Public Types

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.

         value PER_VERTEX_INDEXED
     }
 
 

 

Member Enumeration Documentation

enum SoTextureCoordinateBinding::BindingThe 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.

Member Function Documentation

void SoTextureCoordinateBinding::initClass (void) [static]Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

Reimplemented from SoNode.

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

Reimplemented from SoNode.

References SoAction::getState(), SoField::isIgnored(), and value.

Referenced by callback(), GLRender(), and pick().

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.

References doAction().

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.

References doAction().

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

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

References doAction().

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.

References PER_VERTEX_INDEXED, SoNode::readInstance(), and value.

Member Data Documentation

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