NAME

       SoTextureCoordinateBundle -

       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.

SYNOPSIS

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 *constaction, const SbBoolforRendering, const
       SbBoolsetUpDefault = 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 is needed during rendering.

   SbBool SoTextureCoordinateBundle::isFunction (void) const
       Returns TRUE if a texture coordinate function should be used.

   const SbVec4f & SoTextureCoordinateBundle::get (const intindex)
       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 intindex) const [inline]
       Send texture coordinates to GL. Should only be used if SoTextureCoordinateBundle::isFunction() is FALSE.

   void SoTextureCoordinateBundle::send (const intindex, 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.
