People, just stop! The problem is now buried under verbose communication. Of course it's my fault for not explaining in detail, but I just wanted to find someone who was willing to take a vague description of the project and take a shot. Anyone who had some extra time on their hands and wanted to earn a few extra bucks would take this job.
The simple problem is I don't know openGL, I'm trying to do something really simple, I'm getting an error trying to add an FBO. It probably has to do with how/when I bind and unbind things. I cannot make any progress on my product until this is taken care of. THE PRODUCT IS SO CLOSE TO BEING FINISHED! All I need is two stupid things. Drawing dots on top of lines and having a brightness buffer. Yes, I agree with everyone, it is simple. I am already drawing lines. It's just a matter of getting the FBO stuff working. After that is taken care of, all the rest of the features is just manipulating variables.
The technique that was suggested is having three fragment shaders and two FBOs. 1. lines, 2. dots, 3. combining into one image. FBO 1 for lines, FBO 2 for dots.

I've had 3 or more people who know OpenGL look at my code and fail to tell me where I'm going wrong. I didn't think giving you my code was going to help any... only because it seems like one really needs to dig into it, get the software running, play with the code, etc. Ok. Yes. I will then resort to letting you help me for free and look at the code. Of course at this point you are probably done with this. As frustrated as you might be, I am 10 times more frustrated.
I've spent too much money too much time on this. I ended up paying a few thousand $ over a few months just to get custom C++ line/dot drawing code (running off of the CPU, written from scratch because I wanted it to be drawn a specific way and thought the code could be made efficient, I didn't think a third-party library (Cario, Anti-Grain, etc.) would do it). When I got the CPU usage down to 100% on reasonable settings is when I realized it was such a waste. I took 3 days and a help from some good friends to create the openGL example, already leagues ahead of the CPU version with much less cost.
I am desperately trying to create something great, a cheap product that is simple both in implementation and execution and will be the foundation for my company. Once again, it's so close to being finished. just need get an FBO working and the next few steps will probably go smoothly. At the same time I have a job to do that pays my bills. I've run out of time to be learning openGL. I'm on the cusp of understanding the basics at this point. I would like to start a scratch project and go through a tutorial and really learn it at this point. But I don't have time right now. I have to get this product released ASAP, I just want this nightmare to be over, I am dipping in to the negative financially and it's making me desperate and crazy. I have to get back to my normal job and catch up on my finances.
