Detailed Description

The SoBumpMapTransform class is used to define 2D bump map transformations.

Bump maps 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:

    BumpMapTransform {
        translation 0 0
        rotation 0
        scaleFactor 1 1
        center 0 0
    }
Since:
Coin 2.2

Member Function Documentation

void SoBumpMapTransform::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 SoBumpMapTransform::doAction ( SoAction action) [virtual]

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

Reimplemented from SoNode.

References SoAction::getState().

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

void SoBumpMapTransform::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 SoBumpMapTransform::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 doAction().

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

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

References doAction().

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

Referenced by SoBumpMapTransform().

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

Referenced by SoBumpMapTransform().

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