Most of the time, a Rolls-Royce is useless for everyday shopping, but pleasant for anyone who can afford it.

When a simulator needs a UI or HMI panel for training purposes, what is important is the process and not the 3D shadows. Why would you buy an expensive UI software and spend time integrating its code with yours, when you can just use the one inside your favorite simulation software ?

vsTASKER HMI builder is based on OpenGL. It uses bitmaps for texturing objects and combines the UI with the simulation core. Less work for the end-user.
