I need to draw pixels very fast on a screen.
I found this interesting page Fast pixel drawing library

I guess OpenGL/PBO is what i need.
I was reading about PBO here http://www.opengl.org/registry/specs/ARB/pixel_buffer_object.txt and here http://www.songho.ca/opengl/gl_pbo.html but i don't get it...
Can someone provide simple example, how to draw pixels on a bitmap on a 2D texture with PBO extension?
