# SoTextureCoordinateBundle(3)

The SoTextureCoordinateBundle class simplifies texture coordinate handling.

## NAME

SoTextureCoordinateBundle - The **SoTextureCoordinateBundle** class simplifies texture coordinate handling.

## SYNOPSIS

\#include \<Inventor/bundles/SoTextureCoordinateBundle.h\>

Inherits **SoBundle**.

### Public Member Functions

### Additional Inherited Members

Protected Attributes inherited from **SoBundle** **SoState** \* **state**\
 The state of the current action.

## Detailed Description

The **SoTextureCoordinateBundle** class simplifies texture coordinate handling.

It is unlikely that application programmers should need to know how to use this class, as it is mostly intended for internal use.

## Constructor & Destructor Documentation

### SoTextureCoordinateBundle::SoTextureCoordinateBundle (SoAction \*const action, const SbBool forRendering, const SbBool setUpDefault = TRUE)

Constructor with *action* being the action applied to the node. The *forRendering* parameter must be *TRUE* if the bundle is to be used for sending texture coordinates to GL during rendering. The *setUpDefault* must be *TRUE* if default texture coordinates should be generated.

### SoTextureCoordinateBundle::~SoTextureCoordinateBundle ()

Destructor.

## Member Function Documentation

### SbBool SoTextureCoordinateBundle::needCoordinates (void ) const

Returns *TRUE* if texture coordinates are needed during rendering.

### SbBool SoTextureCoordinateBundle::isFunction (void ) const

Returns *TRUE* if a texture coordinate function should be used.

### const SbVec4f & SoTextureCoordinateBundle::get (const int index)

Returns the texture coordinates at index *index*. Should only be used if **SoTextureCoordinateBundle::isFunction()** is *FALSE*.

### const SbVec4f & SoTextureCoordinateBundle::get (const SbVec3f & point, const SbVec3f & normal)

Returns the texture coordinates based on *point* and *normal*. Should only be used if **SoTextureCoordinateBundle::isFunction()** is *TRUE*.

### void SoTextureCoordinateBundle::send (const int index) const \[inline\]

Send texture coordinates to GL. Should only be used if **SoTextureCoordinateBundle::isFunction()** is *FALSE*.

### void SoTextureCoordinateBundle::send (const int index, const SbVec3f & point, const SbVec3f & normal) const \[inline\]

Convenience function that will make it transparent to the rendering code if ordinary texture coordinates or function texture coordinates are used.

### SbBool SoTextureCoordinateBundle::needIndices (void ) const

Returns *TRUE* if **isFunction()** is *TRUE*, but the texture coordinate indices are needed either by bump mapping or by one of the other texture units.
