Hi. Thank you for this great website. I need your help; I have written a C++/OpenGL code that basically draws a horizontal line above three squares. The vertices of the line are updating (GL_DYNAMIC_DRAW in its glBufferData) every time it goes through a for loop, while the window is open. everything seems to be working fine, the only problem is that the resulting 2D visualization is extremely rapid! I need it to be very much slower so that I could look at the movement of the line more precisely. Is there any function in GLFW that I could call in order to adjust the speed of going through that for loop basically? Please help me with this question, I’m really close to an important deadline and I need to get this code to work asap! Thank you.
