2.0 Transform Concepts
-
Positioning of objects in the world is achieved through the transform
node
-
The transform node applies scales, rotations and translations to its
children
-
These are applied in the order: scale, rotate, translate
-
To achieve complex repeated transforms, transform nodes may be nested
-
The center field may be used to specify scales and rotations about
points other than 0 0 0
-
Although it is tempting to do so, negative scaling (for reflection) is
forbidden
-
Nested transforms could be very expensive for a browser to calculate
