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)
1 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.
2 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.
