pyOpenGL glfush

glFlush() is a function in PyOpenGL that forces all previously issued OpenGL commands to be executed immediately. This function is useful in situations where you want to ensure that all OpenGL commands are executed before continuing to run your program.

For example, if you have a program that draws a complex scene using multiple OpenGL commands, you may want to use glFlush() to ensure that all objects are rendered before you display the final output on the screen.

Here's an example of how to use glFlush() in PyOpenGL:

import OpenGL.GL as gl

# Draw a complex scene using multiple OpenGL commands
# ...

# Force all previously issued OpenGL commands to be executed immediately
gl.glFlush()

In this example, we import the PyOpenGL library and use the GL module to access the glFlush() function. We then draw a complex scene using multiple OpenGL commands and use glFlush() to ensure that all objects are rendered before continuing to run the program.
