Detailed Description
This node removes nonuniform 3D scaling from the current transformation matrix when traversed by an action. It is used by draggers such as the SoTrackballDragger that need to stay uniformly scaled no matter where they are located in the scene graph.
The magnitude of the new scale is determined by the current transformation matrix and the sizing field. This node does not change the translation or rotation in the matrix.
- File Format/Default
AntiSquish { sizing AVERAGE_DIMENSION recalcAlways TRUE }
- Action Behavior
- SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoGetMatrixAction, SoRayPickAction
Appends the current transformation with a new matrix to create an unsquished result.
