Detailed Description

The SoTexture2Transform class is used to define 2D texture transformations. Textures applied to shapes in the scene can be transformed by 'prefixing' in the state with instances of this node type. Translations, rotations and scaling in 2D can all be done.

The default settings of this node's fields equals a 'null transform', i.e. no transformation.

FILE FORMAT/DEFAULTS:

Texture2Transform {
    translation 0 0
    rotation 0
    scaleFactor 1 1
    center 0 0
}

Member Function Documentation

  SoType SoTexture2Transform::getClassTypeId (void) [static]
This static method returns the SoType object associated with objects of this class.

  SoType SoTexture2Transform::getTypeId (void) const [virtual]
Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and 'downward' casting.

Implements SoBase.

  const SoFieldData ** SoTexture2Transform::getFieldDataPtr (void) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
 Returns the SoFieldData class which holds information about fields in this node.

  const SoFieldData * SoTexture2Transform::getFieldData (void) const [protected], [virtual]
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

  void SoTexture2Transform::doAction (SoAction * action) [virtual]
This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

  void SoTexture2Transform::callback (SoCallbackAction * action) [virtual]
Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.

Reimplemented from SoNode.

  void SoTexture2Transform::GLRender (SoGLRenderAction * action) [virtual]
Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method.

Reimplemented from SoNode.

  void SoTexture2Transform::getMatrix (SoGetMatrixAction * action) [virtual]
Action method for SoGetMatrixAction.

Updates action by accumulating with the transformation matrix of this node (if any).

Reimplemented from SoNode.

  void SoTexture2Transform::pick (SoPickAction * action) [virtual]
Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

Member Data Documentation

  SoSFVec2f SoTexture2Transform::translation
Texture coordinate translation. Default value is [0, 0].

  SoSFFloat SoTexture2Transform::rotation
Texture coordinate rotation in radians (around Z-axis, s is X-axis and t is Y-axis). Defaults to an identity rotation (i.e. zero rotation).

  SoSFVec2f SoTexture2Transform::scaleFactor
Texture coordinate scale factors. Default value is [1, 1].

  SoSFVec2f SoTexture2Transform::center
Center for scale and rotation. Default value is [0, 0].
