how can i measure frames per second in C++ using opengl?

[saadkhan]

hey guys,
plz tell me how can i measure fps (frames per second) in C++ using openGL?

[weaknessforcats]

Maybe a little more detail would help. What kind of frames are you talking about?

[saadkhan]

I need to calculate frames per second (fps) in C++ using openGL.
Actually i have designed an algorithm which will read data from .obj file and draw tht model using openGL. So i need to measure fps for it to get know about my algo`s efficiency.
Anyways thnx for a concern to help me out!!!!

You can measure how much time does it take for your render device to render one single frame and then divide 1 with the resulting time(this gives you current fps),or you could make a average of 1 second(every time your render function is called increase fps count,if 1 sec has elapsed reset the counter and count again)
