Yes it's a 3D mesh of polygons but you do need what they call bones...
It's called rigging and where you have, say, the mesh of the leg, there will be a few bones there that decide how much the movement of the bones influences the movement of the mesh. So if you moved the leg bone you would not want it to influence the neck and so on. This is termed 'weighting' and is generally done in the modelling program, eg Blender.
Haptek is dead yes. You guys must really love Hal to keep on at it for all these years so good luck to you. If you ever want to get Daz models animated then your best bet is Unity at the moment or possibly the Unreal Engine.
Here's Unity :
http://unity3d.com/You can import from Daz into Unity. Here's something I worked on a while back :
https://www.youtube.com/watch?v=reSdHa3sCyUThis is a Daz character connected to a basic AIML bot, as you can see from some of the responses, the AI is lacking.
If you don't want to mess around a lot with the Daz to Unity problem then there is this new company made by the people behind Daz...
https://www.morph3d.com/These are ready made for Unity, but you need to buy them - for what you get the price is very good though imho.
I've not heard anything from Rob in a long long time, so I wonder if he has given up on Hal now.
While I am popping in I'd also like to invite you all to take a look at a new forum for CGI that I set up :
http://cgiforum.co.uk/This is the kind of thing I expect to be discussed there - I'll see about writing some tutorial about the Daz/Unity thing in the new year some time I hope.
Anyway, Happy New Year you mad lot !
