Detailed DescriptionThe SoGLDisplayList class stores and manages OpenGL display lists​. The TEXTURE_OBJECT type is not directly supported in Coin​. We handle textures differently in a more flexible class called SoGLImage, which also stores some information about the texture used when rendering​. Old code which use this element should not stop working though​. The texture object extension will just not be used, and the texture will be stored in a display list instead​.

SoGLDisplayList::SoGLDisplayList (SoState * state, Type type, int allocnum = 1, SbBool mipmaptexobj = FALSE)Constructor​.

---

Member Function Documentation

---

void SoGLDisplayList::ref (void)Increase reference count for this display list/texture object​.

---

void SoGLDisplayList::unref (SoState * state = NULL)Decrease reference count for this instance​. When reference count reaches 0, the instence is deleted​.

---

void SoGLDisplayList::open (SoState * state, int index = 0)Open this display list/texture object​.

---

void SoGLDisplayList::close (SoState * state)Close this display list/texture object​.

---

void SoGLDisplayList::call (SoState * state, int index = 0)Execute this display list/texture object​.

---

void SoGLDisplayList::addDependency (SoState * state)Create a dependency on the display list​.

---

SbBool SoGLDisplayList::isMipMapTextureObject (void) constReturns whether the texture object stored in this instance was created with mipmap data​. This method is an extension versus the Open Inventor API​.

---

SoGLDisplayList::Type SoGLDisplayList::getType (void) constReturn type​. Display list or texture object​.

---

int SoGLDisplayList::getNumAllocated (void) constReturn number of display lists/texture objects allocated​.

---

unsigned int SoGLDisplayList::getFirstIndex (void) constReturn first GL index for this display list​.

---

int SoGLDisplayList::getContext (void) constReturn an id for the current context​.

---

void SoGLDisplayList::setTextureTarget (int target)Sets the texture object target Since Coin 2​.5

---

int SoGLDisplayList::getTextureTarget (void) constReturns the texture target Since Coin 2​.5
