Window / OpenGL and Threading

« on: May 18, 2011, 09:22:48 am »

Alright so I've been playing around with SFML for a few days now, just for a bit of fun. I've decided to try to get it working with two threads, one to handle input, audio and the like, and the other to loop through a 3d scene and perform all the rendering tasks. The trouble is, I'm not sure if I'm getting this down correctly, presently I have a black filled window, that handles input and everything fine, but nothing from the rendering thread draws to the window. I've debugged and checked to make sure everything is running as I expect it to, so I'm guessing I've misinterpreted the docs on how to accomplish this. Here's what I've got thus far (just the important parts obviously):

Main Thread
App has a sf::Window as a member

Code: [Select]


App::Init()
{
    // Creates and sf::Window
    sf::VideoMode videoMode(iWidth, iHeight, 32);
    mWindow.Create(videoMode, "AppNameHere");
}

App::Loop()
{
    while(!quit)
    {
        mWindow.SetActive();

        // Process Events for close, resize ect here

        mWindow.Display();
    }

    mWindow.Close();
}


Render Thread
Renderer Class has a sf::Context as a member

Code: [Select]


Renderer::Init()
{
    // Set GL States and Projection Matrix
}

Renderer::Loop()
{
    while(!quit)
    {
        mContext.SetActive();

        // OpenGL Commands here

    }
}



This is what I gathered from searching about thus far. Any help would be greatly appreciated =]
