Hello Dr.Radu, I was trying to have the NED frame simulated in the visualization. I have set the gravity vector as (0.0,0.0,-9.8) as I need it to be.
I figured out how to set the visualization the way I wanted it to be. I am sorry I wasn't as clear before. Here are the changes I made to have the visualization flip around the way I wanted it to be. In line 525 of ChIrrCamera.cpp: rotX = (f32)vec2d.getAngle() + (f32)180; // --> Added 180deg in X-rotation to flip the camera from Z up to -Z up and this worked out for me. Thank you for your help.
