    You need to install the drivers for your graphics card.

    In your screenshot, it says "OpenGL 1.1 (GDI Generic with 2 ext.)". This is the default, built in, fallback software driver

    First of all, you have to find out what you are actually trying to accomplish. I can't think of any application that will ever need all unicode code points at the same time.

    You have to understand how the processor architecture that this is run on works. Branches in general are very bad for performance.

    Shader executions are basically divided into groups, where each...

    What problem? This function call binds "position" to vertex attribute array 0. Above you configured the vertex attribute 0 to be read from the specifed VBO.


    There is your problem. You are not...

    That doesn't make sense. Scaling means multiplying it by some factor. That is something completely different than moving one corner.

    What I had in mind was something like this:

    First of all, that code shouldn't even compile. You have a function declaration inside your OnMouseClick function.

    Second, what was that code intended to do? Scale the polygon when the mouse...

    And you think a magic, pre-packaged IDE is a good solution? That's one of the things I absolutely hated in electronics engineering. Almost every microcontroller vendor seems to think like that.

    Handling mouse clicks, etc. is not part of OpenGL(R). The OpenGL(R) specification onyl specifies an abstract API for rasterization based rendering.

    There are functions related to SDL_RWFromFile that can write to a file pointer. Also, the "w" mode would only overwrite the file anyway, so you end up having a file
