front to back render?

Discussion and feedback on Construct 2

@Ashley - just some thoughts, if you do a ftb render of everything , without btf render, (ignoring any problems with that) and with the culling , does it then makes it faster, and is there a speed difference in btf and ftb without culling, can you test the amount of fillrate change?

putting a couple of big rotating squares on each other should be a good test , did you test on a gpu limited pc

well i do hope this gets somewhat of a succes, if not now maybe on reviewing

Note the front-to-back render doesn't actually draw any pixels to the screen, it only fills a depth buffer. The back-to-front renderer is still necessary for anything to appear on-screen at all.

@Ashley

I'm not sure how you are implementing things, but maybe these links may be of some utility to you (if you haven't found them on your own):
