Detailed Description

The SoGLDisplayList class stores and manages OpenGL display lists.

The TEXTURE_OBJECT type is not directly supported in Coin. We handle textures differently in a more flexible class called SoGLImage, which also stores some information about the texture used when rendering. Old code which use this element should not stop working though. The texture object extension will just not be used, and the texture will be stored in a display list instead.

Constructor & Destructor Documentation

◆ SoGLDisplayList()

SoGLDisplayList::SoGLDisplayList	(	SoState *	state,
		Type	type,
		int	allocnum = 1,
		SbBool	mipmaptexobj = FALSE )

Constructor.

Member Function Documentation

◆ addDependency()

void SoGLDisplayList::addDependency ( SoState * state )

Create a dependency on the display list.

◆ call()

void SoGLDisplayList::call	(	SoState *	state,
		int	index = 0 )

Execute this display list/texture object.

◆ close()

void SoGLDisplayList::close ( SoState * state )

Close this display list/texture object.

◆ getContext()

int SoGLDisplayList::getContext ( void ) const

Return an id for the current context.

◆ getFirstIndex()

unsigned int SoGLDisplayList::getFirstIndex ( void ) const

Return first GL index for this display list.

◆ getNumAllocated()

int SoGLDisplayList::getNumAllocated ( void ) const

Return number of display lists/texture objects allocated.

◆ getTextureTarget()

int SoGLDisplayList::getTextureTarget ( void ) const

Returns the texture target

Since: Coin 2.5

◆ getType()

SoGLDisplayList::Type SoGLDisplayList::getType ( void ) const

Return type. Display list or texture object.

◆ isMipMapTextureObject()

SbBool SoGLDisplayList::isMipMapTextureObject ( void ) const

Returns whether the texture object stored in this instance was created with mipmap data. This method is an extension versus the Open Inventor API.

◆ open()

void SoGLDisplayList::open	(	SoState *	state,
		int	index = 0 )

Open this display list/texture object.

◆ ref()

void SoGLDisplayList::ref ( void )

Increase reference count for this display list/texture object.

◆ setTextureTarget()

void SoGLDisplayList::setTextureTarget ( int target )

Sets the texture object target

Since: Coin 2.5

◆ unref()

void SoGLDisplayList::unref ( SoState * state = NULL )

Decrease reference count for this instance. When reference count reaches 0, the instance is deleted.
