I’ve a query about 3D in Java. The way to add and show non-skeletal animation?

I’ve a query about 3D in Java. I would like a program to point out a 3D mannequin, which is a panel with buttons, a display screen and toggle switches. While you click on on a button or toggle swap, the corresponding animation with this mannequin is performed. Is it doable that I downloaded this mannequin from Blender with the suitable animations, then once I click on on a button, one of many animations is performed?
Is it doable to switch supplies and textures from Blender and have it work within the animation?
If that’s the case, what’s the best technique to do it?
Is there an choice to obtain the mannequin in .obj format and use the contents of that file to animate particular person objects (buttons, display screen, and so forth.)?
