Hi all, I’m new to OpenGL and learning fast
I have a section on my screen that take allot of CPU to create.
I would like to just calculate the drawing once and just reuse it.
If i have to recalculate the drawing every time I render, it can max out the cpu.
I’ve been looking into glReadPixel and glDrawPixel.
I would like to grab a rectangle off the screen after the screen is drawn and just glDrawPixel it any time I want to render new objects on top of it.
However I’m having no success and have not been able to find any examples on Google. any help is appreciated.
