This is the position of the hair when no forces (such as gravity)
are acting upon it. You can use these curves to influence the shape
of the hair.
Rest Curves/Posi-
tion
Working with Rest curves is like styling hair with hairspray. The
Rest curves are styled into curls and flips, etc. When the simulation
is played back, the hair adheres to the Rest curves position as
much as possible depending on dynamic forces and attribute
settings in the hair system and follicles. For example, if your hair
is not very stiff and youre simulating a windy day, the hairspray
(Rest curves position) is less likely to hold the hair in position.
This is how the hair behaves when you play the simulation, which
includes dynamics. Do not edit the Current Position; just view it.
Current Position
The Stiffness and Iterations attributes in the Hair systems Dynam-
ics section are what control the tolerance of the Current Position
achieving the Rest Position.
In this lesson you are introduced to some of the basic concepts of hair by
creating a simple long hairstyle. In this lesson, you learn how to:
Create hair on a surface.
Play a hair simulation and interact with it during playback.
Manipulate hair curves to create a hairstyle.
Use collision constraints to make hair collide with a models head, neck
and shoulders.
Modify hair attributes.
Set up hair self shadows.
Render hair.
Lesson setup
In this lesson, you'll work with a scene we created for your use.
1 Before beginning the lesson, do the steps in
Preparing for the lessons on
page 755.
2 Open the scene named hairStart.mb that is located within the
GettingStarted/Hair directory of your Maya project.
