    Re: FBO using Render Buffers

    Ok, I will try the GL_LINES along with trying the app on another system with a different graphics card.

    Is there a better way to handle what I need?

    Re: FBO using Render Buffers

    blink,

    How can I tell if multisampling is enabled for the main frame buffer? I can check the project and verify this. I know for sure we are not calling glEnable for multisampling like Alfonse...

    blink,

    What exactly does the filtered texture do differently than a normal texture? I tried it with a normal texture? Is this the key part?

    Re: FBO using Render Buffers

    blink,

    On another note, I did try setting up a texture image as the color after realizing the render buffer for color wasn't giving me the smoothing I wanted. Using a texture image for color...

    Re: FBO using Render Buffers

    blink,

    Re: FBO using Render Buffers

    Thanks for the quick reply.

    By smoothing, I mean having all the edges look nice and smooth (no jagged edges). Our code for enabling smoothing is:
