Additional Inherited Members

The SoMultiTextureImageElement class is yet to be documented.

FIXME: write doc.

Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Since:

Coin 2.2

SoMultiTextureImageElement::~SoMultiTextureImageElement ()\fC [protected]\fP, \fC [virtual]\fP

The destructor.

void * SoMultiTextureImageElement::createInstance (void)\fC [static]\fP

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

void SoMultiTextureImageElement::initClass (void)\fC [static]\fP

This static method initializes static data for the SoMultiTextureImageElement class.

void SoMultiTextureImageElement::setDefault (\fBSoState\fP *conststate, \fBSoNode\fP *constnode, const intunit = \fC0\fP)\fC [static]\fP

Resets this element to its original values.

void SoMultiTextureImageElement::set (\fBSoState\fP *conststate, \fBSoNode\fP *constnode, const intunit, const \fBSbVec3s\fP &size, const intnumComponents, const unsigned char *bytes, const WrapwrapS, const WrapwrapT, const WrapwrapR, const Modelmodel, const \fBSbColor\fP &blendColor)\fC [static]\fP

FIXME: write doc.

const unsigned char * SoMultiTextureImageElement::getImage (\fBSoState\fP *conststate, const intunit, \fBSbVec2s\fP &size, int &numComponents)\fC [static]\fP

FIXME: write doc

const unsigned char * SoMultiTextureImageElement::getImage (\fBSoState\fP *conststate, const intunit, \fBSbVec3s\fP &size, int &numComponents)\fC [static]\fP

const \fBSbColor\fP & SoMultiTextureImageElement::getBlendColor (\fBSoState\fP *conststate, const intunit = \fC0\fP)\fC [static]\fP

FIXME: write doc.

SoMultiTextureImageElement::Model SoMultiTextureImageElement::getModel (\fBSoState\fP *conststate, const intunit = \fC0\fP)\fC [static]\fP

FIXME: write doc.

SoMultiTextureImageElement::Wrap SoMultiTextureImageElement::getWrapS (\fBSoState\fP *conststate, const intunit = \fC0\fP)\fC [static]\fP

FIXME: write doc.

SoMultiTextureImageElement::Wrap SoMultiTextureImageElement::getWrapT (\fBSoState\fP *conststate, const intunit = \fC0\fP)\fC [static]\fP

FIXME: write doc.

SoMultiTextureImageElement::Wrap SoMultiTextureImageElement::getWrapR (\fBSoState\fP *conststate, const intunit = \fC0\fP)\fC [static]\fP

FIXME: write doc.

const unsigned char * SoMultiTextureImageElement::getDefault (\fBSbVec3s\fP &size, int &numComponents)\fC [static]\fP

FIXME: write doc.

void SoMultiTextureImageElement::push (\fBSoState\fP *state)\fC [virtual]\fP

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.

Reimplemented in SoGLMultiTextureImageElement.

SbBool SoMultiTextureImageElement::matches (const \fBSoElement\fP *element) const\fC [virtual]\fP

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.

\fBSoElement\fP * SoMultiTextureImageElement::copyMatchInfo (void) const\fC [virtual]\fP

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.

void SoMultiTextureImageElement::setElt (const intunit, const uint32_tnodeid, const \fBSbVec3s\fP &size, const intnumComponents, const unsigned char *bytes, const WrapwrapS, const WrapwrapT, const WrapwrapR, const Modelmodel, const \fBSbColor\fP &blendColor)\fC [virtual]\fP

FIXME: write doc.

SbBool SoMultiTextureImageElement::hasTransparency (const intunit = \fC0\fP) const\fC [virtual]\fP

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 in SoGLMultiTextureImageElement.

int SoMultiTextureImageElement::getNumUnits () const\fC [protected]\fP

Get the number of units with image data set.
