Hell Everyone and thank you for attention .
i have a question about opengl and its capabilities . i am working on a monitoring system , that requires to showing some 2D gauges on the display and i want to create this by OpenGL under linux .
the job requires some OOP features , and to reach this i want to know , does OpenGL Have Capability To Create a Buffer( bitmap ) on RAM and draw some lines and circles and also some other bitmaps on that Buffer ?!
in better words , i want to know can OpenGL flush its output to a buffer ?!
after that , finally combine a set of such buffers ( each buffer for a gauge ) into a another big buffer ( the whole of display ) and show that buffer in VGA output .
Does OpenGL has such capability ?!
