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 = 1 
)

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 is 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.
