IGES (Initial Graphics Exchange Specification) The Initial Graphics Exchange Specification (IGES) is an ANSI standard that defines a neutral form for the exchange of information among dissimilar computer-aided design (CAD), computer-aided manufacturing (CAM) systems, and computer visualization systems. 3ds Max implements the IGES standard for translating files to the software from IGES file formats used by the mechanical engineering and entertainment industries. Using the IGES import feature, you can read in native NURBS on page 8060 data between 3ds Max and other programs such as Autodesk Mechanical Desktop® (release 3.0 or later), Maya®, Pro/ENGINEER®, SOFTIMAGE®, CATIA®, and others. For complete details on the IGES standard, see The Initial Graphics Exchange Specification (IGES) Version 5.3. IK Blend In biped freeform animation on page 7988, the IK Blend parameter determines how forward kinematics on page 7987 and inverse kinematics on page 8016 are blended to interpolate an intermediate position. Using an arm to move a hand is an example of forward kinematics. Using the hand to move the arm is an example of inverse kinematics. This parameter is located in the IK section of the Key Info rollout on page 4367. IK Goal In history-independent inverse kinematics (HI IK) on page 3392 and the IK Limb Solver on page 3444, the IK goal is the object associated with the end joint of a kinematic chain. By default, its name is IK Chain01. The kinematic chain is a single branch of a hierarchy used for animation with inverse kinematics (IK) on page 8016. The chain starts with the end joint and travels up through ancestors until it reaches the start joint. When you move the IK goal, the IK solver then uses IK calculations to move and rotate all other objects in the kinematic chain to react to the object you moved. NOTE You can move the IK goal away from the end joint, which causes the IK chain to straighten out. When you move the goal back toward the end joint, joints in the IK chain will bend again. 8008 | Glossary

IGES (Initial Graphics Exchange Specification)

The Initial Graphics Exchange Specification (IGES) is an ANSI standard that

defines a neutral form for the exchange of information among dissimilar

computer-aided design (CAD), computer-aided manufacturing (CAM) systems,

and computer visualization systems.

3ds Max implements the IGES standard for translating files to the software

from IGES file formats used by the mechanical engineering and entertainment

industries. Using the IGES import feature, you can read in native

NURBS

page 8060 data between 3ds Max and other programs such as Autodesk

Mechanical Desktop

(release 3.0 or later), Maya

, Pro/ENGINEER

SOFTIMAGE

, CATIA

, and others. For complete details on the IGES standard,

see The Initial Graphics Exchange Specification (IGES) Version 5.3.

IK Blend

In biped

freeform animation

on page 7988, the IK Blend parameter determines

how

forward kinematics

on page 7987 and

inverse kinematics

on page 8016 are

blended to interpolate an intermediate position. Using an arm to move a hand

is an example of forward kinematics. Using the hand to move the arm is an

example of inverse kinematics.

This parameter is located in the IK section of the

Key Info rollout

on page 4367.

IK Goal

history-independent inverse kinematics (HI IK)

on page 3392 and the

IK Limb

Solver

on page 3444, the IK goal is the object associated with the end joint of a

kinematic chain. By default, its name is

IK Chain01

The kinematic chain is a single branch of a hierarchy used for animation with

inverse kinematics (IK)

on page 8016. The chain starts with the end joint and

travels up through ancestors until it reaches the start joint. When you move

the IK goal, the IK solver then uses IK calculations to move and rotate all other

objects in the kinematic chain to react to the object you moved.

NOTE

You can move the IK goal away from the end joint, which causes the IK

chain to straighten out. When you move the goal back toward the end joint, joints

in the IK chain will bend again.
