Ok, I'm playing around a bit with 3D graphics and programming, and one thing that I've tried to find information on but failed, is how to make a facegen program similar to those in RPGs. Like, you have a basic head model and the player can make the jaw wider, the eyes smaller etc.

I'm using blender, and apparently this is doable in blender since some have made a program called makehuman, which is like a character creation program without a game, and it was first developed as a blender plugin.

I understand roughly what I have to do = create an interface, make some parts of the head model "moveable" and write a program so that when the player moves a slider the face will change. I would need more explicit information however because I'm very much a beginner at this sort of stuff. I mean, I can create a head model, but everything else is pretty much

If anyone knows any good sites where I can find information about how character creation programs are made and perhaps even tutorials on things like, making a game interface in blender, I would be grateful.

Those are many tutorials for blender: http://www.blender.org/support/tutorials/

Thanks, but I'm already pretty familiar with blender, if that wasn't obvious. I'm asking more specifically about the mechanics behind a facegen program and how to make an interface.

Might still find something interesting there though.

It depends if you are coding this yourself, but most of the subcomponents i.e ui is dependant on what you are coding in.

At a high level the way slider work is using morph target / shape keys (depending on terminology usage) essentially it is a way to interpolate vertex positions.

The easiest explanation is the way the body slider is created using 2 meshes and depending on your slider value you alter the vertex positions of all the vertices.

Thanks, that was helpful. I found some stuff on morph target/shape key and will look into that.
