| If you can draw in anime style then you can use the rotoscoping technique.|
Draw the anime character's head from top, side and front views. Then you stick those views into their respective orthoginal counterparts in the view ports of your modeling program.
Then you can model. My favorite modeling method is by taking a cube primitive and extruding the faces and lining up the points with the picture in the orthoginal view ports. In the areas that you need more detail you just add more vertices to the edges and then place them.
My favorite layout to work in is the traditional quad view and it's helpful if your modeling program has at least an auto framing function to move each view port onto the active component being edited and the ability to zoom in rotoscoping mode while keeping the zoom level perceptively the same as the zoom level for the geometry.
There are other methods that work quicker than what I described here. There is a program called ZBrush that has an extremely intuivite and quick modeling tool called ZSpheres. If you're interested try visiting
The program is more expensive than Milkshape, but it takes a lot of the work out of making models.
