@SDL users, use OpenGL

Don't get me wrong. SDL is wonderfull for 2d graphics, to a point. But, there are just some things that can't be ignored. 1) Software rendering in many cases is faster than hardware rendering. Does this seem wrong to anybody else? 2) No stretch blitting, No blending other than alpha, and no rotation. A super nintendo has hardware level support for this, so why not PC's? Oh, wait, they do... 3) It is slow. No matter how you look at it, speed is always going to be an issue. What can't be done in hardware has to be done in software, and sometimes, there isn't even support for hardware level functions at all. Last time I looked, Direct Draw, heck, even the GDI had support for stretched blitting. There is a soft stretch function, but I had to dig deep into the source to find it. Ok, now you are all mad because I exposed the flaws. But don't be. Doing 2d in OpenGL requires a bit more setup at first, but the rewards are worth the effort. Some of you are aware of a library I have been working on. Drew and Wryzy have helped me a ton working on it. I have called it hxRender. Now, there are 2 ways you can use this. As I have included all the source, you can use that as a tutorial to build your own framework, or you can use the libraries I have provided. As of right now, there is no documentation, and there are no samples. I am writing a sample program right now to demonstrate the capabilities of this library. In theory, it is almost identical to SDL's built in rendering package, except where I have added functionality. There are 3 libraries, hxRender, which handles all of the OpenGL rendering. hxSDL, which provides an interface to integrate with SDL for window setup, and hxUtility, which fills the gaps of whatever else doesn't fit. I built almost all of it from scratch, I have given credit where it is due for the stuff I couldn't do on my own, as much as I can remember anyways.. If you feel you deserve credit for someting, PM me and let me know so I can give it where it is due. If you have any questions, feel free to ask them here, PM me, or send me an email. Thanks. Here it is for download. hxRender version 0.7 (18.3KB) If anybody wants to port to linux, that would be great. [Edited by - PnP Bios on January 9, 2005 1:43:46 PM]

I have a question here. If I were to post some amazing code right now, and not give it any license notice, then would it legally be considered public domain?

I'd assume so, unless someone other than the original IP owner was the one that posted it. I.E. if someone simply posts code on this forum, it is not automatically in the public domain, only if that poster was the one that created it.

Do you or anyone know of some resources to back that up? I'm trying to convince a friend to pull some of his code from a forum, or at least add a license to it. He thinks it's automatically copyrighted and there are no worries, but I'm not so sure.
