public class SoTextureEnabledElement extends SoReplacedTextureElement
Enables/disables textures. This element enables/disables textures. This is implemented as a separate element from the TextureImageElement 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 GLTextureImageElement and the GLTextureImageElement, but 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.

    Modifier and Type
    Method
    Description
    static void
    disableForShapeCache(SoState state, int unit, boolean disable)
    Specify that a texture unit is not used by any shape, so we don't have to invalidate cache when this texture is enable/disable/modified.
    static boolean
    get(SoState state)
    Calls get(state, (int)0).
    static boolean
    get(SoState state, int unit)
    Used by shapes to figure out if they need to send texture coordinates.
    static int
    getClassStackIndex()
    Deprecated.
    As of Open Inventor 9.3.0.0.
    static boolean
    getDefault()
    By default there is no texture.
    static boolean
    isDisabledForShapeCache(SoState state, int unit)
    Return if that texture unit is not used by any shape, so we don't have to invalidate cache when this texture is enable/disable/modified.
    void
    pop(SoState state, SoElement prevTopElement)
    Overrides pop() method so side effects can occur in GL.
    void
    push(SoState state)
    Overrides push() so we can remember previous element's value and avoid making GL calls if this element has the same value.
    static void
    set(SoState state, boolean value)
    Calls set(state, value, (com.openinventor.inventor.nodes.SoNode)null).
    static void
    set(SoState state, boolean value, SoNode node)
    Used by GLTextureImageElement, set to true when a non-null image is set, set to false when there is no texture image (the default).
