You should use SDL.

In that case, you start a new threat to ask questions about that. Otherwise it's just confusing.

So where is the library installed? Where are the header files? Are those directories in the search path?
Also, how comfortable are you using Linux? You don't come across as though you're very familiar with it, in which case you might like to read up on how to do things (like set environment variables).

do_line() is a function I use a lot normally. Of coarse we already discussed polygon rendering and triangulation using the earclip method, but I sense now that we're going to be using the GPU 2D polygon rendering will need to advance too. In my opinion Allegro should do everything it can to make it easier to make games without turning into one of those cut/paste game maker suites.

FTFY.

I for one enjoyed your post

I assumed he means people will expect more out of the 2D polygon renderer now that it uses the GPU. I could be wrong.

Well, the Allegro 4 one already does arbitrary self-intersecting polygons. I expect Allegro 5 will support paradoxical ones fit for bringing down the Borg.

I don't think allegro even supports Triangulation. Maybe it will in the future, but even just D3D and OpenGL just finally hot support for it. After I don't know how many years.

Fixed That For You

Apparently OpenGL has has had shader tessellation for 3 years, this document discussing how to use it was 1st published in 2007-06-26. As for OpenGL polygon tessellation, I found it a little unwieldy to use, but it got the job done when I needed it to.

I have never directly used D3D so I can't pass comment on it.

I guess this is one of those things, that a few cards would have supported it, but unless you have general market take up of the technology, implementing it into a game or engine is a money hole, (unless your game/engine lives long enough to see it be taken up by the market.)

I can find cards that could do hardware tessellation back then, but I can not seem to find information if they were supported as OpenGL extensions. Truform was one hardware tessellation system, from 2001, but it was dropped before it was standardised, (and lack of market takeup.) But other than that, it seems September last year was when cards started supporting it. But I am still sure there are some random crazy cards produced by someone that would have been able to do it.

I love Allegro.cc, its a place where even when people completely agree with each other, they can still argue.
