New category request.

Post by Kolgrima »

Wasn’t sure where to put this but this section seems to be the best spot. This is a request to the admins for a new forum category for LTE. I think it would be very helpful to filter all questions regarding LTE into one spot, both to LTE users as well as Irrlicht users. The gap between the modified Irrlicht 1.0 and current Irrlicht is quite large, and a separate category may help prevent frustration on both ends.

Cheers

LTE is based on Irrlicht, but is an independent project. It's not even using the same license as Irrlicht so code from LTE can't be copied back into Irrlicht (though I'm glad to see that they have at least opensourced it now). So it would make more sense if you ask the LTE Studios to create a forum for their engine.

There should be no practical problem with copying anything from LTE into Irrlicht, since as I've mentioned before, LTE must either be dual licensed (zlib + LGPL), or it is violating Niko's copyrights, since just about the only thing that the zlib license prohibits is removing it.

Two wrongs don't make a right, but two violations make an effective defence against action. People who play lawyers on Slashdot are welcome to disagree.

The zlib does not cover changes.

LTE request

Post by Kolgrima »

A very reasonable suggestion and one worth pursuing to be sure, that said... I have now made a formal request to the project leader of LTE, for a User Forum. I will let you know the results.

This projects' license confuses me somewhat. Irrlicht's headers have been replaced with LGPL. One header I saw said BSD. ???

One thing: if this project is for the PSP (PlayStation Portable) then I may be able to port it to Playstation3. Releasing it may be tricky, but I myself would be interested in seeing some of my own Irrlicht stuff running on a PS3. 8)

I also thought the zlib license doesn't cover changes. The original code is covered by the zlib license but the additions are released as LGPL, which affects the original code virally.

Either way it sucks, the LTE guys made an effort to change the engine enough to make reintegration almost impossible. It would have made much more sense to submit their changes as patches then stick their game engine and build system on top as an external wrapper. Not only would they be up to date with all the latest features and bug fixes, we would have supported their game studio with free advertising and increased their user base. Also their additions would have given us a head start for other OpenGL ES(que?) platforms like Nokia Symbian, iPhone and one day OpenMoko. :roll:

Oh well, I suppose it's never too late.

And if they'd chosen to license just their changes under the LGPL, that would be fine and dandy.

However, in removing the zlib license from the original source, they are violating Niko's copyrights. Swiping their source would be just as 'bad', but might serve as a piquant lesson in why you should respect others rights if you want them to respect yours.

Not that I'm advocating doing it, but it really does hack me off when zealots insist on stealing something which was given to them (very nearly) freely.

Have you done any PSP dev? It uses a SCE graphics library which seems pretty similar to OpenGL but i guess you'd just have to basically write a driver using the different function names...

Hmmm. May be easier to just target Irrlicht's OpenGL driver via PSGL.

I haven't done any PSP stuff. Doing AAA PS3 stuff is enough to keep me occupied. :?

:lol: definetly, the only PSP stuff i did was before my PS3 devkit was up and running so was just a bit of time wasting in a way, though not at all a waste of time!
