Hi everyone! I need to make this code smarter and more interactive. In particular, I would like the user to select the presence or absence of panels in the command window; for example in the following code in addition to the body of the object (a cube so 6 facets) there are two panels (each of these two panels has 2 planes, therefore 4 total planes and therefore a matrix u_normale_panels 4x3 ). Each of these panels has an area of 20 m^2 and a reflectivity of 0.8. I would like the user to choose IN THE COMMAND WINDOW whether or not there are additional panels(and consequently the total number of facets), their area (area panels) and their reflectivity (rho_panels)in order to obtain the elements that I have defined as u_normale, rho and area in the code.
