IK Solution
Inverse kinematics (IK) uses a goal-directed method where the animator
positions a child object and the program calculates the position and orientation
of the parent objects. The final position of the hierarchy after all of the
calculations have been solved is referred to as the IK solution.
Applied IK requires that one or more parts of your IK structure be pinned to
animated follow objects. Once pinned, you select any object in your kinematic
chain and click the Apply IK button. The software then calculates the IK
solution for each frame of the animation and places transform keys for every
object in the IK chain.
Illuminance
Illuminance is the
luminous flux on page 7833 incident on a surface of unit
area. It measures how much energy has fallen on a surface.
This quantity is useful for describing the level of illumination incident on a
surface without making the measurement dependent on the size of the surface
itself. The lux (lx) is the International System (SI) unit of illuminance. The
American System (AS) unit for illuminance is the footcandle (fc), equivalent
to 1 lumen per square foot. Illuminance is a function of the distance from the
light source. To specify the illuminance of a light, you must enter a value in
lx, and the distance at which that illuminance is measured.
