Detailed Description

The SoGLMultiTextureImageElement is used to control the current GL texture for texture units.

Constructor & Destructor Documentation

◆ ~SoGLMultiTextureImageElement()

SoGLMultiTextureImageElement::~SoGLMultiTextureImageElement ( void )

protectedvirtual

The destructor.

Member Function Documentation

◆ createInstance()

void * SoGLMultiTextureImageElement::createInstance ( void )

static

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

◆ initClass()

void SoGLMultiTextureImageElement::initClass ( void )

static

This static method initializes static data in the SoGLMultiTextureImageElement class.

◆ push()

void SoGLMultiTextureImageElement::push ( SoState * state )

virtual

This method is called every time a new element is required in one of the stacks. This happens when a writable element is requested, using SoState::getElement() or indirectly SoElement::getElement(), and the depth of the current element is less than the state depth.

Override this method if your element needs to copy data from the previous top of stack. The push() method is called on the new element, and the previous element can be found using SoElement::getNextInStack().

Reimplemented from SoMultiTextureImageElement.

◆ pop()

void SoGLMultiTextureImageElement::pop	(	SoState *	state,
		const SoElement *	prevTopElement
	)

virtual

This method is callled when the state is popped, and the depth of the element is bigger than the current state depth. pop() is called on the new top of stack, and a pointer to the previous top of stack is passed in prevTopElement.

Override this method if you need to copy some state information from the previous top of stack.

Reimplemented from SoElement.

◆ set()

void SoGLMultiTextureImageElement::set	(	SoState *const	state,
		SoNode *const	node,
		const int	unit,
		SoGLImage *	image,
		const Model	model,
		const SbColor &	blendColor
	)

static

Sets the current texture. Id didapply is TRUE, it is assumed that the texture image already is the current GL texture. Do not use this feature unless you know what you're doing.

◆ hasTransparency() [1/2]

SbBool SoGLMultiTextureImageElement::hasTransparency ( SoState * state )

static

Returns TRUE if any of the images have at least one transparent pixel.

Since: Coin 3.1

◆ hasTransparency() [2/2]

SbBool SoGLMultiTextureImageElement::hasTransparency ( const int unit = 0 ) const

protectedvirtual

Called by containsTransparency(). Returns TRUE if image data has transparency. Default method does a very poor job of detecting this, since it returns TRUE when the number of components are 2 or

Override whenever it is important to know this (SoGLTextureImageElement overrides it to avoid transparency handling where possible).

Reimplemented from SoMultiTextureImageElement.

◆ getMaxGLTextureSize()

int32_t SoGLMultiTextureImageElement::getMaxGLTextureSize ( void )

static

The size returned by this function will just be a very coarse estimate as it only uses the more or less obsoleted technique of calling glGetIntegerv(GL_MAX_TEXTURE_SIZE).

For a better estimate, use SoGLTextureImageElement::isTextureSizeLegal().

Note that this function needs an OpenGL context to be made current for it to work. Without that, you will most likely get a faulty return value or even a crash.
