I have this problem to solve, hope that you can help me: I have a building with a “control system”. The control system, depending of the temperature inside and outside the building, opens and closes windows automatically. I want to create a 3D model of the building that displays in real time the processing mode of the building (temperature inside and outside, windows that are open and closed, etc). For that I have to interconnect the “control system” of the building with a computer. The control system give data (temperature inside and outside, windows that are open and closed, etc) in format txt. I want also to be able to use the computer to give commands to the control system, i.e., if I want to close a certain window I want to be able to do it with the computer. So my question is if DirectX is the best program to do these. Kind regards, Gustavo
