Mark: Best way to make a FBO?

[AdamStrangeParticipant]

Hi Mark. This is a bit more unusual. I am wanting to know your recommendation for making and using a FBO?

The first thing I am NOT using Mojo3d, just opengl and   Method OnRenderGL() Override

I have no issues with what it does, how it does it, shader, all that stuff. It’s the actual setup and base use I would like some help with.

I looked into Mojo3d deferredRender, but everything is encapsulated, so is not really any help.

 

in essence I am wanting to offscreen render RGB, depth, normals, maybe some other stuff like positions, custom data to FBO

FBO (preferably with no transfer from the gpu) shader denser of said above  – you know what I’m up to.

 

What are your suggestions for best practice?

Would be nice to have any feedback on this one. Even if it is ‘Go Away’

First google result for ‘opengl FBO tutorial’ looks useful:

http://www.opengl-tutorial.org/intermediate-tutorials/tutorial-14-render-to-texture/

I’d also recommend looking at mojo/graphics/rendertarget.monkey2.

Thanks Mark, I’ll let you know how I get on. or not. lol

small report. Not got the FBO working yet. But got all the base processing sorted:

depth, automatic normals, position, color

Here’s a quick look. basically showing depth darkening, object color and matrix.

Had to do a redesign on the base system to allow highly optimised multi-low poly render.
