iOS 8.1.1 + Ogre 1.9

[buratino]

Hi. Couple of days ago i started to learn/play with Ogre. Appears it doesn't work out of the box. Here is several issues i had:

1) macBundlePath() + "/../Documents/" isn't valid with iOS 8 (couldn't save/load ogre.cfg);
2) running OS X program within simulator 8 isn't valid (this technique was used to identify XCode's path);
3) render system OpenGL ES 1.x won't compile because of missing *.mm files (i see fixes in default branch but not merged in stable 1.9);
4) device orientation support for windowed mode is broken (wrong and duplicated height/width swaping);
5) windowed mode for render system OpenGL ES 1.x is broken (didn't accept ViewController if it's not root);
6) hlsl2glsl is not complete: no x86_64 arch in iOSDependencies, had to recompile it manually and also adjust Ogre to fit latest hlsl2glsl API;
7) no GL ES 3 support. Ogre won't compile with that option enabled because of some missing declarations (actually don't need that but it could be interesting to see deferred lighting example with Ogre on iOS).

I managed to fix them locally (except gles3) and now have working demo (Ogre in UIView).
Here is my changes:

dd4dd55_simulator_8_1.patch

But few questions left (especially after i found out about iOS's SceneKit framework).
a) Are mentioned issues known?
b) Is iOS support planned or deprecated, or it's totally depends on volunteers?
c) What's the latest stable Ogre branch/commit?
d) What branch is bleeding edge, v2-0? Lots of forum-threads mention v1-10, but i can't find such thing.

what do you mean by planned -OGRE already supports IOS - and yes OGRE is open source volunteer project -
you can also fork OGRE add and fix commit etc...http://www.ogre3d.org/developers/submit-patch

c) What's the latest stable Ogre branch/commit?

latest "stable" is 1.9 - how ever afaik 1.10 don't suffer from special problems and will soon be declared "stable"
off course "stable" is just a word...and after "stable" comes 1.11 1.12 etc, all "stable"...

d) What branch is bleeding edge, v2-0? Lots of forum-threads mention v1-10, but i can't find such thing.

2-0 is the "bleeding edge" but right now due to internal policies the most important parts of it are not released yet....it is also very buggy/unstable/incomplete so right now its more like "bleeding" but without the "edge"

1.10 is now the default branch, while 1.9 has its own branch...
you can find all on the bitbucket...https://bitbucket.org/sinbad/ogre/

Code: Select all

what do you mean by planned -OGRE already supports IOS

Guess i got used to OS X where it seems like everything works out of the box. Thus Ogre 1.9 + Xcode 6 + iOS 8 feels like a bit deprecated.
By "planned support" i'd like to know if anyone else is going to get Ogre back in line.
I think I'll submit few pull requests in the near future, just need to figure out better approach than hardcoding strings

And thank you for clarification about versions. I thought 2-0 is after 1-9

masterfalcon used to do the apple support, but I assume real life nabbed him as I haven't seen him around. Submit pull requests

A lot of people make that mistake with version numbers, the numbers are all independant

Hi,

Thanks buratino! The patches look good and I've pushed the changes.

iOS support is not deprecated. I've been really busy with work and life and just haven't had the time to keep it up to date recently.

Awesome, gles3 now works too (without glsl-optimizer)!
DeferredShading looks nice
