Foil 92 Animation - II

From VRML 2 Basic Concepts and Definitions CPS616 -- Information Track of CPS -- Spring Semester 97. by Zeynep Ozdemir(Geoffrey C. Fox)
An animation which is independent of the exact date and time at which it is played back can be described by fractional time.
  • In this technique, it is assumed that an animation starts at fractional time 0.0 and ends at fractional time 1.0.
Animation descriptions use a technique called keyframe animation where a position or rotation is specified for only a few key fractional times.
  • The position or rotation values at these times are called key values.
  • Using keyframe animation, an animation description specifies only a few positions or rotations, instead of an infinite number of them.
