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.

SoMaterialBundle::SoMaterialBundle

(

SoAction *

action

)

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

SoMaterialBundle::~SoMaterialBundle

(

)

Destructor

Member Function Documentation

void SoMaterialBundle::setUpMultiple

(

void

)

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

void SoMaterialBundle::sendFirst

(

void

)

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

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.

SbBool SoMaterialBundle::isColorOnly

(

void

)

const

Returns TRUE if the current light model is BASE_COLOR.

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()).
