# Transformations and Coordinate Space Conversions

In the scene hierarchy, the position, rotation, and scale of a GroupNode object (e.g. Camera, Geometry, or Light) are determined by a parent node which is a Transformation object. This object can be accessed via the method GroupNode::Transformation().

The rotation, scale, and translation transformations represented by a single Transformation object are applied in the following order:

1. scaling
2. rotation
3. translation

Note that multiple transformations in a hierarchy are not composed. Only a node's most immediate ancestor transformation is used to determine the position, rotation, and scale of an object in the scene.

Coordinate Systems

Similarly to Autodesk Maya's coordinate system, Mudbox's Y axis corresponds to the up/down axis in the viewport.

A Transformation object is also used to perform conversions to and from world and local space coordinate systems.
