Hello Community,
I wrote a little programm in OpenGL, where I have an 3D-Object with specific coordinates from an 3D-Camera. In my OpenGL windows I can rotate, zoom and move this Object, but now I want to display die x,y,&z-coordinate, where my mousecursor is clicking at.
I´m new in programming with OpenGL and I have no idea what I have to look for.
At the moment my program shows me the coordinates from the screen but not the 3D-coordinates. I just want to display the values, which i get from the camera for each vertex, which I´ve created.
Any Ideas?
P.S:Sorry for my bad english.
