In Topic: Render to a texture without using a FBO ?

26 May 2013 - 06:13 PM

There more I think about it, the more this does look like a glCopyTexImage job.  Problem with being rusty is that the most obvious solutions don't leap to mind !


I've heard enough horror stories about pbuffers that I deliberately avoided them - and hence my post here!


Thanks for listening guys, I'll go have a play  :)

Ah, thanks for that - and indeed that will work, but I deliberately want (and need) to render to a texture.


Back story:-   I've already got all the textures I need for this project (there's a LOT of them) but they're geared up for a full-screen program. What I want to do is draw to a full-sized (hidden) texture, and then copy that texture to the screen - reducing its size as I do so.


I hope that makes sense... it's 01:30 here and I'm past tired!!


Thanks :)

Apologies for the tardy catch-up.. life gets in the way sometimes!

Thanks for the helpful pointers, I'll have a memory-refresh from the Red Book and try your suggestions.

Cheers :)

Thanks CE - a great explanation, very helpful indeed.

Apologies for not thanking you sooner - Other problems at this end.

All the best!

In Topic: Apply texture with separate alpha mask

23 February 2010 - 10:59 AM

They say a picture is worth a thousand words...

Looky here: www.aerobits.org/shade

the 'mask' image gives the center of the instrument some shading which gives the illusion that it's a sphere - like the real thing.

I've piddled about with blendfunc all evening and can't crack it.
