SoGLMultiTextureImageElement::~SoGLMultiTextureImageElement (void) [protected], [virtual]¶

The destructor.

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.

void SoGLMultiTextureImageElement::initClass (void) [static]¶

This static method initializes static data in the SoGLMultiTextureImageElement class.

void SoGLMultiTextureImageElement::init (SoState * state) [virtual]¶

FIXME: write doc.

Reimplemented from SoMultiTextureImageElement.

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.

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.

void SoGLMultiTextureImageElement::set (SoState *const state, SoNode *const node, const int unit, SoGLImage * image, const SoTextureImageElement::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.

SbBool SoGLMultiTextureImageElement::hasTransparency (SoState * state) [static]¶

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

Since

SbBool SoGLMultiTextureImageElement::hasTransparency (const int unit) const [protected], [virtual]¶

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

4.

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

Reimplemented from SoMultiTextureImageElement.
