Class SoTextureEnabledElement

  • 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 9300.
      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).
