this is a new start from a previous post. Long story short, I m rendering my scene to a FBO and use it as RTT. Now, I d like to fill the Main Buffer with what I just renderer off-screen.
My first question is, is there a way to avoid using glBlitFramebuffer for this?
Zed said yes but im not sure how.
Can we say, render off-screen on buffer x and to the main buffer at the same time?
Even better… render on the main frame buffer and bind it to a texture as well?
I would rather use one of those options then use the glBlitFramebuffer… even though I tried to figure glBlitFramebuffer out, I can’t have it to working yet…
If the BlitFrameBuffer is not supported, bind a texture (color attachement) to your FBO, then when you are done rendering to the FBO, simply render a full screen quad to your backbuffer with that texture bound.
Hope that helps.
