If the model is not too big and the computer is not too slow, the computation runs fast enough to create a
dynamic animation in real time or close to that. However, for many larger models, the computation is too
slow to give you a dynamic impression of the model's movement. The model view then provides the
opportunity to save the individual frames for subsequent processing into a video animation that you can play
at any speed you like.
This lesson looks into the functionality of the Model View, and even though you can probably use it
intuitively, you may also pick up a useful trick or two you did not know about.
As usual, we need a model to work on. For this tutorial you can pick any model you may have, or you can
download the familiar dumbbell example here: demo.arm2d.any
. You will also need the accompanying STL
file: dumbbell.stl
.
Load the model into the AnyBody Modeling System and click Window -> Model View (new). You should get a
window looking like this:
• The model is centered in the window, and you should be able to see all its elements. When you
open a new Model View, the window automatically applies a Zoom All function that shrinks the view
until all elements are visible.
• The model is not necessarily assembled correctly. All the segments at load time are positioned
where they are defined in the AnyScript model. These positions rarely comply with the kinematical
constraints such as joints. In fact, you might want to assemble the model above correctly by
running the SetINitialConditions operation in the ArmStudy at the lower left corner of the screen.
