3-D Animations with the ADINA Fast Graphics Engine

In ADINA v. 9.0, we introduced a new graphics engine that enables fast visualization and manipulation of large models in the ADINA User Interface (AUI). Various features of this Fast Graphics Mode (FGM) of display were described in the following Tech Briefs.

  • New ADINA Graphics Engine for Fast Visualization
  • The ADINA Fast Graphics Mode
  • Since then, we have continued to make improvements so that FGM supports many more capabilities within the AUI. One recent major improvement is the creation of animations using the fast graphics engine which we will highlight in this Tech Brief.

    Animations created in standard graphics mode are essentially sequences of 2-D images displayed on the screen. Hence, during playback, the animation cannot be rotated or zoomed. In contrast, animations created in FGM are true 3-D animations which can be rotated, zoomed and moved to view any particular part of the model during playback as illustrated below. The first movie illustrates the ability to pause the animation and examine certain parts by zooming and rotating the model. In the second movie, the model is rotated and zoomed while the animation is in progress.



    In ADINA v. 9.7, the following additional improvements were made to the creation and saving of 3-D animations in FGM.

    • Animations can be created on multiple mesh plots
    • A new playlist feature is available to manage multiple animations
    • Animations stored in a playlist can be selected for display or deletion
    • A playlist containing animations can be saved and loaded back for display later
    • New animations can be added to a current playlist

    The movie below shows animations on multiple mesh plots. The modal stresses for two mode shapes are displayed and each animation can be manipulated individually as illustrated.



    The ADINA Fast Graphics Engine provides powerful post-processing visualization that enhances understanding of results.
