For the people who are using hoops to visualize theire results, when you  do an animation, which method do you use? 

When I animate something (displacement and deformation), I displace all the points of the tessalation one by one by calculating the new position in my code and then write the new value in the array of points. It's quite slow when there is a lot of vertices. Maybe there is a way of moving the whole array of points in one operation, at least for the rigid displacement. Do you know something like that?

Hi,

I would try the key frame animation which you can see with the hoops file lgear.hsf.

If you open this file using HoopsPartViewer, you can see segment structure by using "Tools/Segment Browser", and also animation data using "Tools/Keyframe Editor".

In the Browser Window, you can see that there are 50 segments, and each segment contains sub segments and individual shells in it.

Only one segment is visible at a time, and the visibility of these segments are controlled by HOOPS animation capability.

If you click small gray rectangle, the visibility will be changed. You can place your hoops geometry in each segment like this.

This technique is not good from memory consumption standing point of view, but this might be faster than editing points.
