Remember that the technique youchoose should be tested thoroughly before you go into actual production so thetechnique that can be fitted into the production pipeline from the start. Many times, your choice ofsoftware dictates the way the hair is produced. Whichtechnique you choose depends on a variety of factors.

Others will need to be more scraggly, with patches of skin showing through.įigure 8 When the sphere is rendered, differing hair densities create different looks.Īs you can see, there are quite a few methods for creating hair. Density of the hair is also important (see Figure 8.) Some characters will need to be totally fluffy, with a very high hair density. Some packages use a bitmap to define the color of the hair, so creating a leopard with spots is an easy task. These will allow you to control and sculpt the direction of the hair (see Figure 7).įigure 7 In Maya, these master hairs (green) show the general shape and direction of the hair. To help speed things along, most packages provide an interface that allows for a few "master" hairs to control the rest.

Manipulating hair using third-party software can be difficult, particularly when there are lots of hairs. Anotheradvantage is that rendering looks more realistic because the individual hairscan cast shadows into the scene file. The big advantageto creating hair as geometry is that the hair can collide with obstacles, so itallows for longer hairstyles that can interact with the environment. To get a realistic look, however, you need to createlots of geometry, which drives up render times considerably. The more sophisticated plug-ins, such as Maya's Hair, actually createhair as individual strands. Most of this type of software tends tochoke when the hair needs to interact with the character, such as long hairflowing over the shoulders. The downfall is that this technology works best with shorterhairstyles, such as crew cuts and fur. Some examples of this are Digimation's Shag:Furplug-in for 3DS max, as well as Softimage's Mental Ray fur shader.īecause no actual geometry is created, environment hair renders reasonablyquickly. One of the more economical ways to create hair is as a 2D environment effect.The hair is calculated after the image is rendered and automatically iscomposited into the shot. Hair software falls into several broad categories.
Still, you will need to know how they workto get the most out of them. Manysoftware applications have hair plug-ins available to automate the process. The method outlined previously will work with just about any 3D package. Digital Character Animation 2, Volume II: Advanced Techniques
