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

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.

References center, SoAction::getState(), rotation, scaleFactor, scaleOrientation, SbMatrix::setTransform(), and translation.

Referenced by callback(), GLRender(), and pick().

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.

References doAction().

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.

References center, doAction(), SoFieldContainer::get(), SoAction::getState(), rotation, scaleFactor, scaleOrientation, SbMatrix::setTransform(), and translation.

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.

References center, SoGetMatrixAction::getTextureInverse(), SoGetMatrixAction::getTextureMatrix(), SbMatrix::inverse(), SbMatrix::multLeft(), SbMatrix::multRight(), rotation, scaleFactor, scaleOrientation, SbMatrix::setTransform(), and translation.

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

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

References doAction().

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

Referenced by doAction(), getMatrix(), GLRender(), and SoTexture3Transform().

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

Referenced by doAction(), getMatrix(), GLRender(), and SoTexture3Transform().

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

Referenced by doAction(), getMatrix(), GLRender(), and SoTexture3Transform().

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

Referenced by doAction(), getMatrix(), GLRender(), and SoTexture3Transform().

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

Referenced by doAction(), getMatrix(), GLRender(), and SoTexture3Transform().
