Detailed DescriptionThe 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', ie no transformation​. FILE FORMAT/DEFAULTS: Texture2Transform { translation 0 0 rotation 0 scaleFactor 1 1 center 0 0 } See also SoTexture3Transform

Member Function Documentation
SoType SoTexture2Transform::getTypeId (void) const [virtual]Returns the type identification of an object derived from a class inheriting SoBase​. This is used for run-time type checking and 'downward' casting​. Usage example: void foo(SoNode * node) { if (node->getTypeId() == SoFile::getClassTypeId()) { SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type } }For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses​. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode​.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine​.h (for engine classes) and so on​. For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups​. Implements SoBase​.
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 who wants to throw geometry primitives at OpenGL overrides 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::translationTexture coordinate translation​. Default value is [0, 0]​.
SoSFFloat SoTexture2Transform::rotationTexture coordinate rotation in radians (around z-axis, s is x-axis and t is y-axis)​. Defaults to an identity rotation (ie zero rotation)​.
SoSFVec2f SoTexture2Transform::scaleFactorTexture coordinate scale factors​. Default value is [1, 1]​.
SoSFVec2f SoTexture2Transform::centerCenter for scale and rotation​. Default value is [0, 0]​.
