Detailed Description
Enables/disables 3D textures.
This element enables/disables 3D textures. This is implemented as a separate element from the TextureImage3Element so the texture image can be changed without invalidating caches containing shapes -- shapes need to know if texturing is going on or not so they can decide to send down texture coordinates or not.
This element is set by the GLTextureImage3Element and the GLTextureEnabledElement. The interaction between the three elements is a little complicated. Each of the other two elements always sets up the GL texture state appropriately, however, texturing is only enabled if both elements agree that it should be enabled (they check each other's value before calling set).
This element cannot be overridden, but, since the elements that set it check each other's value, overriding those elements has the same effect.

Member Function Documentation
Used by shapes to figure out if they need to send texture coordinates.
| static int SoTexture3EnabledElement::getClassStackIndex | ( | ) | [static] |
Returns the stack id for this element.
Reimplemented from SoReplacedTextureElement.
Reimplemented in SoGLTexture3EnabledElement.
| static SoType SoTexture3EnabledElement::getClassTypeId | ( | ) | [static] |
Returns the type identifier for this class.
Reimplemented from SoReplacedTextureElement.
Reimplemented in SoGLTexture3EnabledElement.
| static SbBool SoTexture3EnabledElement::getDefault | ( | ) | [inline, static] |
By default there is not texture.
| virtual void SoTexture3EnabledElement::pop | ( | SoState * | state, | |
| const SoElement * | prevTopElement | |||
| ) | [virtual] |
Overrides pop() method so side effects can occur in GL.
Reimplemented in SoGLTexture3EnabledElement.
| virtual void SoTexture3EnabledElement::push | ( | SoState * | state | ) | [virtual] |
Overrides push() so we can remember previous elements value and avoid making GL calls if this element has the same value.
Reimplemented from SoReplacedTextureElement.
| static void SoTexture3EnabledElement::set | ( | SoState * | state, | |
| SbBool | value, | |||
| SoNode * | node = NULL | |||
| ) | [static] |
Used by Texture3ImageElement, set to TRUE when a non-null image is set, set to FALSE when there is no 3D texture image (the default).
