Make Human

I've been waiting for an open source Poser and a Z-Brush like sculpting tools. Now that Make Human is here we have them both!

Sharp Construct came out awhile ago and ended up being included into Blender 3D. This gives you the ability to sculpt a 3-D mesh like you do in Z-Brush. Simply amazing and powerful.

Make Human is similar to Poser 3D. You can edit, pose, and render the human form. Also see Daz Studio, it's not open source, but it's free and really nice.

If you need to quickly create the human figure or organic models on a budget, these may come in handy.
