Animate Scene Submenu

   

A molecule in VMD can contain any number of coordinate sets; the resulting molecular trajectory may be played back in order to animate the molecule. This submenu contains commands to control the animation, much like the controls for a VCR or tape player. The animation can also be controlled via the Animate form. The commands available in this submenu are:

• Animate Scene play forward 
  Causes the animation to start playing forward through the frames which have been read into memory.
• Animate Scene play reverse 
  Plays the animation in reverse.
• Animate Scene step 1 forward 
  Advances the animation one frame forward, and then pauses it. If the end is reached, the animation goes back to the initial frame.
• Animate Scene step 1 reverse 
  Advances the animation one frame backwards, and then pauses it. If the start of the animation is reached, the last frame is displayed.
• Animate Scene pause 
  Pauses the display at the current frame.
• Animate Scene goto start 
  Sets the currently displayed frame to be the initial frame, and pauses the animation.
• Animate Scene goto end 
  Sets the currently displayed frame to be the final frame, and pauses the animation.
• Animate Scene Style 
  This submenu controls how the animation behaves when it reaches the beginning or end of the trajectory. The following styles may be selected:
  • Animate Scene Style Once 
    When the end of the trajectory is reached (or the beginning, if the molecule is being animated in reverse), the animation will be paused at the last (first) frame.
  • Animate Scene Style Loop 
    Causes the animation to loop around back to the start of a trajectory when the end is reached, or vice versa if playing in reverse.
  • Animate Scene Style Rock 
    Causes the direction in which the animation is playing to reverse when the end or start of the trajectory is reached.
