Detailed Description

The SoTexture3Transform class is used to define 3D 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 3D can all be done.

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

Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Member Function Documentation

SoType SoTexture3Transform::getClassTypeId (void) [static]

This static method returns the SoType object associated with objects of this class.

Reimplemented from SoNode.

SoType SoTexture3Transform::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 ** SoTexture3Transform::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.

Reimplemented from SoNode.

const SoFieldData * SoTexture3Transform::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 SoTexture3Transform::initClass (void) [static]

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

Reimplemented from SoNode.

void SoTexture3Transform::doAction (SoAction *action) [virtual]

This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

void SoTexture3Transform::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 SoTexture3Transform::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 SoTexture3Transform::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 SoTexture3Transform::pick (SoPickAction *action) [virtual]

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

Member Data Documentation

SoSFVec3f SoTexture3Transform::translation

Texture coordinate translation. Default value is [0, 0, 0].

SoSFRotation SoTexture3Transform::rotation

Texture coordinate rotation (s is x-axis, t is y-axis and r is z-axis). Defaults to an identity rotation (ie zero rotation).

SoSFVec3f SoTexture3Transform::scaleFactor

Texture coordinate scale factors. Default value is [1, 1, 1].

SoSFRotation SoTexture3Transform::scaleOrientation

The orientation the texture is set to before scaling. Defaults to an identity rotation (ie zero rotation).

SoSFVec3f SoTexture3Transform::center

Center for scale and rotation. Default value is [0, 0, 0].
