(Same bear cub skull–WireFusion rendering has a perspective; 3DCT can render it orthogonally)
We use two competing formats for delivering 3D images over the Internet, namely WireFusion and 3DCT. 3DCT is only viewable on Windows machines but we still use this format for two reasons: (1) it excels in generating detailed yet small 3D models; (2) 85% of our visitors use a version of Windows. So if you are a Windows user, we strongly recommend that you try 3DCT images for the best morphological experience. If you install the free 3DCT Viewer, you can also view these images in PowerPoint slides (see an earlier post)—great asset for giving a lecture.
WireFusion, on the other hand, is Java based so it is viewable on different operating systems, including Windows, Mac OS X and Linux. We use it as our default format for this very reason. We also like the fact that they now have a free version. Wirefusion is not as efficient in conveying detailed shape data compared to 3DCT but has many interactive fuctions that we do not fully utilize at this point.
We should note that we used default compression for 3DCT, whereas we played with options within WireFusion to make the models look better (we may not be using the optimal options, however).
