Public Member Functions | |
| virtual void | init (SoState *state) |
| Initializes element. | |
| virtual void | push (SoState *state) |
| Override push() and pop() methods to maintain GL state. | |
| virtual void | pop (SoState *state, const SoElement *prevTopElement) |
| void | sendDiffuseByIndex (int index) const |
| Send diffuse color and transparency, by index Included for compatibility with SoMaterialBundle To be used by a shape to send additional colors after first send() Should NEVER be the first send of a shape! | |
| void | reset (SoState *state, uint32_t bitmask) const |
| Destroy knowledge of GL state. | |
| void | send (const SoState *state, uint32_t mask) const |
| Sends indicated component(s) to GL: Only sends if value is not already in GL. | |
| virtual SbBool | matches (const SoElement *) const |
| note: matches, copyMatchinfo not used by this element. | |
| virtual SoElement * | copyMatchInfo () const |
| Create a copy that we can put in a cache used list and call matches() on later. | |
| SbBool | lazyMatches (uint32_t checkGLFlag, uint32_t checkIVFlag, const SoGLLazyElement *eltInState) |
| Replace matches() for this element: matches "this" element GL or IV state with values in eltInState. | |
| SoGLLazyElement * | copyLazyMatchInfo (SoState *state) |
| Replaces copyMatchInfo for this element: makes a GLLazyElement with some initialization. | |
| void | getCopyGL (SoGLLazyElement *cacheLazyElement, SoGLLazyElement::GLLazyState &cacheGLState) |
| method that makes a copy of GL state at cache close(). | |
| void | copyBackGL (SoGLLazyElement *cacheLazyElement, SoGLLazyElement::GLLazyState &cacheGLState) |
| method that copies GL state back into "this" element after cache has been called. | |
| void | sendVPPacked (SoState *state, const unsigned char *pcolor) |
| Send a packed color (not in state). | |
| virtual | ~SoGLLazyElement () |
| Note: destructor is public, so cache can delete its copy. | |
| void | mergeCacheInfo (SoGLRenderCache *childCache, SoGLRenderCache *parentCache, uint32_t doSendFlag, uint32_t checkIVFlag, uint32_t checkGLFlag) |
| void | updateColorVBO (SoState *state, SoVBO *vbo) |
| Update the passed VBO with the packed colors if the diffuse/transparency node ids do not match. | |
Static Public Member Functions | |
| static void | sendAllMaterial (SoState *state) |
| Static sends, always send top-of-stack. Intended for extender use. | |
| static void | sendNoMaterial (SoState *state) |
| static void | sendOnlyDiffuseColor (SoState *state) |
| static SbBool | isColorIndex (SoState *state) |
| static SoGLLazyElement * | getInstance (const SoState *state) |
| Return the top (current) instance of the element in the state Note it does NOT cause cache dependency! It also casts away the const. | |
| static void | initClass () |
| Initializes the SoGLLazyElement class. | |
Detailed Description
Note that this class relies on SoLazyElement to store the inventor color(s), etc. in the instance. This element keeps GL shadow copies of colors

only copies if bit in bitmask is set. also sets invalidBits to FALSE for these components.

| SoGLLazyElement* SoGLLazyElement::copyLazyMatchInfo | ( | SoState * | state | ) |
also initializes cacheSetBits to zero.

goes from state="this" to cacheGLState only copies if bitmask (GLSend of cache lazy element) is set.
