Animation Auto Ease Options

 
Animation Auto Ease Options:
 
  • The auto ease options specifies the speed curve of an animation.
 
 
 
  • SimLab composer comes with various predefined motions, a motion is type of composer generated animation that is used for creating predefined animations such as round table, follow path wheel motions for selected object and round table and helical motions for cameras.

Regular keyframes:
 
  • SimLab composer presents three types of ease that automatically adjusts the influence into and out of a key frame to smooth out sudden changes in translation, rotation and scale. these options are auto ease out, out ease in and auto ease. with these options users can ease speed of an object when coming into or out of a key frame or both, where (auto ease out) is used is to ease speed coming out of a selected key frame, (auto ease in) is used to a speed coming in to a selected key frame, and (ease) is used to a speed coming both into and out of a selected key frame.
 
  • With animation ease options, you can easily achieve smoother and more realistic motion for geometries and camera in your 3D scenes.

Description
No Ease
  • Regular animation keyframe without any ease type applied
  • Maintain constant speed at the keyframe itself from the direction of previous keyframe.
  • Maintain constant speed from the keyframe itself to the direction of next keyframe
Ease out
  • Regular animation keyframe with ease out applied
  • Acceleration
  • Maintain constant speed at the keyframe itself from the direction of previous keyframe.
  • Accelerate (speed up or increase speed) from the keyframe itself to the direction of next keyframe.
Ease in
Deceleration
Regular animation keyframe
Decelerate (slowdown or decrease speed) at the keyframe itself to the direction of previous keyframe.
Maintain constant speed from the keyframe itself to the direction of next keyframe
 Ease
 Deceleration then acceleration
Regular animation keyframe
Decelerate (slowdown or decrease speed) at the keyframe itself to the direction of previous keyframe.
Accelerate (speed up or increase speed) from the keyframe itself to the direction of next keyframe.
 
 
 
 
In the image above, The darker the red gradient color, the faster the object is.
 
 
 
  • The first keyframe of Box 2 has a speed of 0 with an influence of 100% on its right side. Auto Ease Out automatically adjusts the influence out of a keyframe. The object gradually accelerates as it leaves first keyframe until it reaches last keyframe, where it reaches its maximum speed. Keep in mind that Auto Ease Out requires an existing next keyframe in order to take effect.
 
 
 
  • The first keyframe of Box 3 has a speed of 0 with an influence of 100% on its left side.  Auto Ease In automatically adjusts the influence into a keyframe.  The object starts at its maximum speed and slows down as it approaches last keyframe. Keep in mind that Auto Ease In requires an existing previous keyframe in order to take effect
 
 
 
  • Both of first and last keyframes of Box 4 have a speed of 0 with an influence of 50% on right side of first frame and left side of last frame.  This automatically adjusts the speed of change, where accelerates as animation retreats from the first keyframe until it reaches maximum speed at frame number 10 and from there decelerates as animation advances toward the last keyframe.
 
 
 
  • The middle keyframe of Box 5 as a speed of 0 with an influence of 50% on both sides. The object slows down as it approaches middle keyframe, and gradually accelerates as it leaves. Keep in mind that Auto Ease requires existing previous and next keyframes in order to take effect on both sides of selected keyframe.
 
 
 
Predefined Motions:
 
  • SimLab Composer comes with various predefined motions.
 
 
 
  • A Motion is a type of Composer-generated animation that is used for creating predefined animations such as Round Table, Follow Path, Wheel motions for selected object, and Round table and helical motions for cameras.
 
 
 
  • In case of predefined motions, start and end frames have a speed of 0 with a default influence of 25% on sides that falls within an animation sequence itself.
 
 
 
  • The symbol of predefined motion provides a simple visual representation that indicates the relative speed at each particular frame within it.
 
 
 
  • Possible parts of predefined symbols with one of ease effects:
The symbol of predefined motion on the animation time-line consists of:
- The animation sequence itself
- Start frame, which acts as a regular keyframe
- End frame, which also acts as another regular keyframe

  • Box 3 has predefined motion with ease in only.
  • Box 4 has predefined motion with ease out and ease in effects.
