## Detailed Description

The SoMaterialBundle class simplifies material handling.

Every shape node should create (on the stack) an instance of this class and call sendFirst() before sending anything to GL. During rendering, send() should be used to send material values to GL.

## Constructor & Destructor Documentation

## SoMaterialBundle()

SoMaterialBundle::SoMaterialBundle | ( | SoAction * | action | ) |

Constructor with action being the action applied to the geometry node.

## ~SoMaterialBundle()

SoMaterialBundle::~SoMaterialBundle | ( |  | ) |

Destructor

## Member Function Documentation

## setUpMultiple()

void SoMaterialBundle::setUpMultiple | ( | void |  | ) |

Currently not in use. It is only provided for OIV compliance.

## sendFirst()

void SoMaterialBundle::sendFirst | ( | void |  | ) |

Sends the initial material values to GL. Must be done once in all geometry nodes before the rendering begins.

## forceSend()

void SoMaterialBundle::forceSend | ( | const int | index | ) |

Will send the material to GL even though index equals the current index.

Provided for compatibility with the SGI Open Inventor v2.1 API.

## isColorOnly()

SbBool SoMaterialBundle::isColorOnly | ( | void |  | ) | const

Returns `TRUE` if the current light model is BASE_COLOR.

## send()

void SoMaterialBundle::send | ( | const int | index,
|  | const SbBool | betweenbeginend )

Sends material values with index index to GL. Will test whether the current index equals index before sending.

betweenbeginend should be `TRUE` if your program is between a glBegin() and glEnd() (it is illegal to change the polygon stipple between a glBegin() and glEnd()).
