Presently the inovani animation technique works for 3D polygon head models. There must be an opening for the mouth, and the face (the part that moves when talking) must be a connected surface. The teeth must be placed so that they do not penetrate the skin when the face speaks. If included, the normals of the surfaces must point "out" of the model. If the eyes are to blink, there must be holes for the eyes and the eye balls must not bulge out of the eye holes.

Elmo was created by Tracy Bezesky at www.contentcreator.com. He was not created in particular for inovani. The 3D model was downloaded as a VRML file and converted to inovani's 3D format that includes data for animation. The advantage with Elmo is that he is very expressive and storing him on file only requires 4KByte. He is easy to animate and can therefore be used on small devices.

Anthon was bought from Zygote that delivers ready-made heads. He arrived as a VRML file. He is the opposite of Elmo in terms of size; he is 74 KBytes large.

The cow was made by Henning Birkeland at www.henningb.com. It was not created specially for inovani, but Henning displayed it on his web-pages to show example work. The cow was found as a VRML file, but is originally created using Maya. This model is so easy to animate that it can run on small CPUs. In our version, the file size is 17 KBytes.

These two characters were created by Henning for inovani using Maya and exporting to VRML. The pig is so easy to animate that it can run on small CPUs; it is 17KBytes large. The horse is only slightly bigger - 23 KBytes - it also runs on small CPU computers, but with a slightly lower frame rate or size of the displayed head.

Diana was found on the net as an illustration in a course on 3D modelling. (These course pages are no longer operating.) Diana is also 17 KBytes large.

"Tough Guy" was found at the Singular Inversions site as a VRML file. We have borrowed him to check that we could animate him. He is a very detailed model and has a texture. He takes 418 KByte including a JPEG texture.

Digimask can generate head models in a variety of sizes where the smaller sized easily run on small CPU devices and the larger sized heads look good on very large screens.
