Hello.
I want to draw 3D model of real phisical-mechanizm.
Is there any ways to use ROOT for my task?
Thanks!!!
I am not sure what you mean by “3D model of real phisical-mechanizm”. I would suggest you to have a look to the TGeoXXX classes. We have examples showing how to use them in ROOTSYS/tutorials (rootgeom.C, geodemo.C, …)
Oh sorry, I was bad elucidate, what I need.
I need to draw 3D model of real apparatus. I tried to use 2D plots, but it was bad idea. 2D plot not allow to draw retired figures.

The lego plot is to visulize the energy deposit in each EMC tower of STAR detector on real time?
Hello, Ruslan
What do you want to draw?
Why do you want to use ROOT? There are a lot of special programms for 3d modelling. Some of them are free and open source, e.g 3d blender. They have specific user interfaces to make modelling MORE NATURAL and simple. With ROOT you’ll need to programm geometry description yourself. I’m not shure, may be some converters from CAD files to ROOT’s geometry exist, but it’s not the best way.
