About the online 3D viewer
The models represented in the 3D viewer are not printer ready models. They are very low resolution in order to display online with ease. Just as with any low resolution image, the closer you zoom in the more pixelated it becomes.
The printer ready models have much more detail and take a good bit of computer power to view in original scale.
Controls for the viewer are:
* left hold mouse button to turn the model in any direction.
* scroll wheel to zoom.
* right hold and drag to move entire body in any direction.
