The SoMultiTextureEnabledElement class is an element which stores whether texturing is enabled or not.
Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.
SoMultiTextureEnabledElement::SoMultiTextureEnabledElement | ( | void | ) | [protected] |
The constructor.
SoMultiTextureEnabledElement::~SoMultiTextureEnabledElement | ( | void | ) | [protected, virtual] |
The destructor.
SoType SoMultiTextureEnabledElement::getClassTypeId | ( | void | ) | [static] |
This static method returns the class type.
Reimplemented from SoElement.
int SoMultiTextureEnabledElement::getClassStackIndex | ( | void | ) | [static] |
This static method returns the state stack index for the class.
Reimplemented from SoElement.
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::initClass | ( | void | ) | [static] |
Initialize relevant common data for all instances, like the type system.
Reimplemented from SoElement.
void SoMultiTextureEnabledElement::init | ( | SoState * | state | ) | [virtual] |
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] |
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.
void SoMultiTextureEnabledElement::enableRectangle | ( | SoState * | state, |
SoNode * | node, | ||
const int | unit | ||
) | [static] |
Enable RECTANGLE texture mode.
void SoMultiTextureEnabledElement::enableCubeMap | ( | SoState * | state, |
SoNode * | node, | ||
const int | unit | ||
) | [static] |
Enable CUBEMAP texture mode.
SoMultiTextureEnabledElement::Mode SoMultiTextureEnabledElement::getMode | ( | SoState * | state, |
const int | unit | ||
) | [static] |
Returns the mode for a texture unit.
void SoMultiTextureEnabledElement::disableAll | ( | SoState * | state | ) | [static] |
Disable all active texture units. Convenient when all textures needs to be disabled before rendering.
SbBool SoMultiTextureEnabledElement::isEnabled | ( | const int | unit | ) | const [protected] |
Returns TRUE if unit is enabled (Mode == DISABLED).
