can someone know Opengl help me , i need a C++ program that draws a simple 2D scene. The scene should consist of three different faces: happy face, sad face, and surprise face. You will apply the transformation that you have learned in the class, as you need. Initially, draw the happy face and make the face rotate around the y-axis, then change to sad face with different color and also make it rotate around the x-axis, finally change to surprise face with different color and also make it rotate around the z-axis.

Try to write object (face) in different function, first write function that draw the face with specific color, write function that draw the eyes, and then write function that draw the mouth. Finally draw the whole scene.

Avoid writing function for each face, all faces parts the same, the only differ in the mouth and eyes

Switch between faces using key presses (keyboard or mouse)

Apply rotation for each face relative to different axis (ex: smiley face rotate

relative to y-axis, sad face relative to X, and surprise face relative to Z)
