public class SoTextureEnabledElement : SoReplacedTextureElement

The SoTextureEnabledElement type exposes the following members.

Public methodStatic memberDisableForShapeCache

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.

Public methodEquals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Public methodStatic memberGet(SoState)
Calls Get(state, System.Int32(0)).
Public methodStatic memberGet(SoState, Int32)

Used by shapes to figure out if they need to send texture coordinates.

Public methodStatic memberGetClassStackIndex Obsolete.

Returns the stack id for this element.

Public methodStatic memberGetDefault

By default there is no texture.

Public methodGetHashCode
Overrides GetHashCode().
(Inherited from SoNetBase.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodStatic memberIsDisabledForShapeCache

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.

Public methodPop

Overrides OIV.Inventor.Elements.SoTextureEnabledElement.Pop(OIV.Inventor.Misc.SoState, OIV.Inventor.Elements.SoElement) method so side effects can occur in GL.

(Overrides SoElementPop(SoState, SoElement).)
Public methodPush

Overrides OIV.Inventor.Elements.SoTextureEnabledElement.Push(OIV.Inventor.Misc.SoState) so we can remember previous element's value and avoid making GL calls if this element has the same value.

(Overrides SoReplacedTextureElementPush(SoState).)
Public methodStatic memberSet(SoState, Boolean)
Calls Set(state, value, (OIV.Inventor.Nodes.SoNode ^)nullptr).
Public methodStatic memberSet(SoState, Boolean, SoNode)

Used by GLTextureImageElement, set to true when a non-null image is set, set to false when there is no texture image (the default).

Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)

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.
