---

Member Function Documentation

---

void SoGLRenderCache::open (SoState * state)Opens the cache​. All GL calls will be cached until close() is called​. See also close() call()

---

void SoGLRenderCache::close (void)Closes the cache​. Should be called after all GL calls​. See also open()

---

void SoGLRenderCache::call (SoState * state)Executes the cached display list​. See also open()

---

int SoGLRenderCache::getCacheContext (void) constReturns the cache context of this cache​. This is used to quickly determine if cache can be used for a state​. This method is an extension versus the Open Inventor API​.

---

SbBool SoGLRenderCache::isValid (const SoState * state) const [virtual]Return TRUE if this cache is valid, FALSE otherwise​. Reimplemented from SoCache​.

---

void SoGLRenderCache::addNestedCache (SoGLDisplayList * child) [virtual]Adds a display list which is called from this cache​. This is to make sure the child display list isn't destroyed too early​.

---

void SoGLRenderCache::destroy (SoState * state) [protected], [virtual]Can be overridden by subclasses to clean up before they are deleted​. Default method does nothing​. Reimplemented from SoCache​.
