Question

OpenGL problem

Draw the entire scene composed with more than 5 objects. Scene should Include rigid transformations such as scale, rotate, translate, etc.

And please write down the code of the application program.cpp file (files containing main, render, etc). Also, show the picture of captured result screen.

you should give 1. code of the application program.cpp, 2. picture of captured result screen(entire scene). Please don't give incomplete answer.
