Aspect ratios are used anywhere a bitmap is created or used. For example:
■ When preparing to render, you can specify an aspect ratio for your rendered
images with the Image Aspect parameter on the
Render Scene dialog on
page 5878 .
■ When setting up a
viewport background on page 89 , you can specify
whether to use the viewport, bitmap or rendering output aspect ratio to
display the bitmap.
■ When you make a spotlight a projector on page 5055 , you can use the
Bitmap Fit option to match the spotlight's aspect ratio to the bitmap's, and
thus prevent the bitmap from distorting.
Attachments (IK)
In biped animation, the biped hands and feet can be linked to the world,
another object in the scene, or to the biped's own body. This linking is also
called IK attachment. Attachment can be blended: this lets you start with one
attachment and end with another. For example, if the biped is catching a ball,
you can start with the hand in body space and end with the hand in the
coordinate space of the ball.
Attenuation

In the real world, the intensity of light diminishes over distance. Objects far
from the light source appear darker than objects near the source. This effect
is known as attenuation.
