Nurbs Patch Avatar
The demo shows all the clicks to make a curvy animated avatar out of 3 nurbs patches converted from 3 nurbs lathes.
For a beginner NurbsPatches are very intuitive to use because to learn what they are all about all one has to do is drag the control points.
To make an animated av there is no need to go past operation 23 (Add eyes)
In getting to operation 23, the biggest challenge will be transferring the ownership. There is nothing difficult or complex about any of the concepts used here but it is very easy to make mistakes if one does not pay careful attention to the number of staves and bands used for the 3 patches.
Operation 24 to 27 continues for those who wish to refine their avatar. These operation show how to fuse the arm and leg nurbs patches to the torso so that the limbs join on more smoothly.
Operation 28 to 44 takes the refining further by editing the triangles at the flat stage so that the actual vertices for the arms and legs can be joined to the torso's vertices.
