Member Function Documentation

  void * SoMultiTextureEnabledElement::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 SoMultiTextureEnabledElement::init (SoState * state) [virtual]
This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects.

Reimplemented from SoElement.

  void SoMultiTextureEnabledElement::set (SoState * state, SoNode * node, const int unit, const SbBool enabled) [static]
Sets the state of this element.

  SbBool SoMultiTextureEnabledElement::get (SoState * state, const int unit) [static]
Return current state of this element for unit.

  void SoMultiTextureEnabledElement::setElt (const int unit, const int enabled) [virtual]
virtual element set function.

  void SoMultiTextureEnabledElement::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 SoElement.

  SbBool SoMultiTextureEnabledElement::matches (const SoElement * element) const [virtual]
This function returns TRUE is the element matches another element (of the same class), with respect to cache validity.

If the application programmer's extension element has a matches() function, it should also have a copyMatchInfo() function.

Implements SoElement.

  SoElement * SoMultiTextureEnabledElement::copyMatchInfo (void) const [virtual]
This function creates a copy of the element that contains enough information to enable the matches() function to work.

Used to help with scenegraph traversal caching operations.

Implements SoElement.

  const SbBool * SoMultiTextureEnabledElement::getEnabledUnits (SoState * state, int & lastenabled) [static]
Returns a pointer to a boolean array. TRUE means unit is enabled and that texture coordinates must be sent to the unit. lastenabled is set to the last enabled unit.

  const SoMultiTextureEnabledElement::Mode * SoMultiTextureEnabledElement::getActiveUnits (SoState * state, int & lastenabled) [static]
Returns the mode of all units. Also returns the last enabled unit in lastenabled.

Since:
    Coin 2.5

  void SoMultiTextureEnabledElement::enableRectangle (SoState * state, SoNode * node, const int unit) [static]
Enable RECTANGLE texture mode.

Since:
    Coin 2.5

  void SoMultiTextureEnabledElement::enableCubeMap (SoState * state, SoNode * node, const int unit) [static]
Enable CUBEMAP texture mode.

Since:
    Coin 2.5

  SoMultiTextureEnabledElement::Mode SoMultiTextureEnabledElement::getMode (SoState * state, const int unit) [static]
Returns the mode for a texture unit.

Since:
    Coin 2.5

  void SoMultiTextureEnabledElement::disableAll (SoState * state) [static]
Disable all active texture units. Convenient when all textures needs to be disabled before rendering.

Since:
    Coin 2.5

  SbBool SoMultiTextureEnabledElement::isEnabled (const int unit) const [protected]
Returns TRUE if unit is enabled (Mode == DISABLED).
