• derived nodes inherit all messages from their base classes
  
• see reset method for default settings
  
• rotations are applied before translation
  
• use the startPosition message to do a pre-translation if necessary
  
• the texture matrix of all instanced object nodes will be changed
  
• use the cache option on child objects to avoid unwanted side effects
  

constructor textureTransform

1 dont include in documentation

destructor ~textureTransform

method reset

1 reset texture matrix to identity

method setTexMat

1 if node type is pfGeode then set geoset material
2 else, if node type is pfGroup

2.1 call setMaterial recursively on all children

method setGeosetTexMat

1 find and setup geostate texture matrix

method message

1 set pre-rotation translational component
2 set rotational component
3 set translational component
4 set scaling component
5 receive matrix key

method app

1 if any child has changed then setMatrix for all child nodes

method setMatrix

1 create scaling matrix
2 multiply by pre-rotational translation
3 multiply by rotation
4 multiply by translation
5 set texture matrix
