In Topic: Independent clip() in Multiple Render Targets

16 August 2012 - 08:20 AM

There's some tricks you could do in DX10/11 for this, but I don't know of any in DX9.

The only hack I can think of is:
If you can guarantee that you've got no overdraw (two triangles covering the same pixel), which you can if you're doing a z-pre-pass, then you can render with additive blending and output black when you don't want to write data.


Yes, I had the same idea, but I'm not doing a z-pre-pass right now and I don't know if it would be too expensive. In any case, I'm pretty sure this solution would work, but I'll leave it as the last option :P

If you're using a pixel shader, you can create another technique that doesn't use the clip funtion and use it for those RTs.

Rememeber that clip doesn't return anything for that pixel, nor does it write any information to the back buffer or depth buffer. On newer graphic cards it stops the execution entirely.


That would work. But is it possible to use different techniques, for the different RT when using MRT?? If it is possible, could you give an example or a resource explaining how to do that? I've not been able to find any :S

Ok, so I think I've enough information. I'll have to think what to do but I think maybe doing something less specific would be a better solution. I'm thinking about something related with Networks or maybe AI.

It is not a problem if the campus is in the USA because I'll only take it if I get a grant that will cover everything (or almost everything). Let's hope I'm lucky :D

Thank you all for your opinions and your advice! I still have some time to decide so let's see what happens!

Ok, let's clarify some things.

First of all, answering to snake5 and also frob I would like to say that definitely NO! I've been playing games my whole life, enjoyed them and in the last years also programming them. So that won't be only a job but a dream I'd like to come true.
Moreover I'm not really a fan of Mega-Enterprises games. I prefer indie and original games.

You're really making me doubt! On the one hand I really like this Universities (FIEA looks so cool!) but on the other hand I don't want to close doors... I'd really apreciate more opinions about that!

I've also seen that some of you talk about spending four years but what I'm searching is something specific of one or two years... maybe the Master concept in Spain is not exactly the same as in the USA.

I hope that helps a little, thank you for your help!
