<p>
Transformation is a combined Translation, and Rotation around Center point, and Scale around Center and with orientation given by <a class="normal" href="Castle3D.T3DTransform.html#ScaleOrientation">ScaleOrientation</a>. For precise order of these operations, see X3D Transform node.
<p>Default values of these fields indicate no transformation. So everything is zero, except Scale which is (1,1,1). Scale must always have all components > 0 (some operations depend that scale here is invertible and doesn't flip sides). Non-uniform scale (e.g. when you scale along X coordinate 2 times, but you scale along Y coordinate 3 times) works... to some extent, that is collisions with spheres (including camera radius) are not perfect in this case. For perfect results, keep your scale uniform.
