NAME

       SoScale -

       The SoScale class is a node type for scaling scene graph geometry.

       Use nodes of this type to apply scaling operations during scenegraph traversals for e.g.
       rendering. Scale values are specified in a triple-value vector, with one scale factor for
       each of the 3 principal axes.

SYNOPSIS

Member Function Documentation

   void SoScale::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 SoTransformation.

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

   void SoScale::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 SoScale::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 SoScale::getBoundingBox (SoGetBoundingBoxAction *action) [virtual] Action method for the
       SoGetBoundingBoxAction.
       Calculates bounding box and center coordinates for node and modifies the values of the
       action to encompass the bounding box for this node and to shift the center point for the
       scene more towards the one for this node.

       Nodes influencing how geometry nodes calculates their bounding box also overrides this
       method to change the relevant state variables.

       Reimplemented from SoNode.

   void SoScale::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 SoScale::pick (SoPickAction *action) [virtual] Action method for SoPickAction.
       Does common processing for SoPickAction action instances.

       Reimplemented from SoNode.

   void SoScale::getPrimitiveCount (SoGetPrimitiveCountAction *action) [virtual] Action method
       for the SoGetPrimitiveCountAction.
       Calculates the number of triangle, line segment and point primitives for the node and adds
       these to the counters of the action.

       Nodes influencing how geometry nodes calculates their primitive count also overrides this
       method to change the relevant state variables.

       Reimplemented from SoNode.

Member Data Documentation

   SoSFVec3f SoScale::scaleFactor Specifies scaling along the 3 axes.
       To get a uniform scale applied to the affected shapes, set the scaleFactor field to a
       vector with the same value for all components.

       A common error when doing non-uniform scaling in a single direction is to set the value
       for the other two components of the scaleFactor vector to 0. This is obviously wrong, they
       should be set to 1 to not scale the shape(s) in the other two directions.

       Be careful with setting scaleFactor component values to 0 or to negative values. Most
       shapes should handle those cases somehow, but the results are undefined unless otherwise
       specified.

       The default value of this vector field is [1.0, 1.0, 1.0].
