What license is this under, dare I ask. Tue, 12 Feb 2002 03:36:00 GMT donotreply@osnews.com (Anonymous) Comments http://osnews.com/thread? http://osnews.com/thread? Excellent question, I'm eager to know too. Because if it's under GPL, I considere it a sad (partial) waste. Still good for open-source games, that would close all door for any viable commercial use...

In fact, is it possible that the source is "open" without any license ? Like no restriction, here's the code, do what you want ! Tue, 12 Feb 2002 04:36:00 GMT donotreply@osnews.com (Anonymous) Comments http://osnews.com/thread? http://osnews.com/thread? Ummm...GLDirect by SciTech actually emulates OpenGL using the
DirectX drivers, while this seems to be the other way round. So
his comment that "...a solution already exists" seems untrue
to me.

Or am I missing something here? Tue, 12 Feb 2002 05:17:00 GMT donotreply@osnews.com (Anonymous) Comments http://osnews.com/thread? http://osnews.com/thread? Once you know how to take the API one way its a simple reversal to perform the DX to GL calls.

If it's under the GPL, commercial game vendors could still buy a non-GPL license from the authors. No problems there.

Ok, great, thanks for the info ! That make sense...

That's definitley something I will propose. For sure it will not be included in R1 (we aim for a complete R5 clone) but for R2 we start adding new things.

Tue, 12 Feb 2002 17:34:00 GMT donotreply@osnews.com (Anonymous) Comments http://osnews.com/thread? http://osnews.com/thread? Just the porting. That help to be source compatible, but not binary compatible.

I personnaly like DirectX as a game API. Programming using this interface under others OS may be fun.

My only concern: DirectX is more than an API, but a kind of direct interface upon hardware drivers that need to be DirectX compliant (espacially video cards drivers) to be really powerfull and usefull.

Having the same API will not give the power of it, unless other OS drivers start to support DX, which I really doubt.

So, the more I think about it, the less I found it of real use except for a quick & dirty port of a Windows game.

Is that make sense ?

Umm, it is not just a reversal to map from one API to another. APIs don't map to each other cleanly. Writing a mapping from GL -> DX is much harder than writing one from GL -> DX because DX incorporates a lot more features, plus it is object based, which makes it harder to map to a C API.

"Writing a mapping from GL -> DX is much harder than writing one from GL -> DX because DX incorporates a lot more features,..."

I agree that DX is more complex due to its object nature, but once you understand the DX object functions and data structures and their relationships to the OpenGL framework it becomes a lot simpler to do the API conversion.

Issues like sound, input etc are a totally different ballgame tho... Wed, 13 Feb 2002 03:51:00 GMT donotreply@osnews.com (Anonymous) Comments http://osnews.com/thread? http://osnews.com/thread? I prefer SDL+GL and its companion libs.
For simple use you can use it plain and for complex uses you can just use the addon lib.
Who cares about DX?

(surely that wrapper wil make easier have quick and dirty conversion but for starting projects SDL+GL is a better choice IMHO complexity wise and portability wise(including Ps2 HW;)) Wed, 13 Feb 2002 09:45:00 GMT donotreply@osnews.com (Anonymous) Comments http://osnews.com/thread? http://osnews.com/thread?

About 99% of every game studio/publishers :-)

Never underestimate the power of the market share :-)
Windows + XBox = DirectX. Which is way sufficient at the eyes of game publishers management ... Wed, 13 Feb 2002 17:38:00 GMT donotreply@osnews.com (Anonymous) Comments
