Irrlicht 1.4.1 for S60 3rd Edition (Nokia 95)

Post by jmpep »

Hello to all.

I would like to announce that I have finished porting Irrlicht to the S60 3rd Edition platform, which is the one run in several Nokia phones.

I own a Nokia N95 8GB, and so it has been my target device, but the port should be able to run at the same speed in the N95 and the N93, as far as I know.

Most of the features of the engine are supported in this port. Including:
  • The possibility of taking screenshots
  • Accessing the file system
  • Rendering to texture
  • The 2D GUI.
  • The mouse pointer is emulated (as the mobile lacks a mouse)
  • QWERTY keyboard is emulated by supporting Multi-tapping input mode.
The features that are not are:
  • Shaders
  • Certain texture clamping modes
  • Local viewer lighting calculations
  • Reflections
The reason why they are not supported is just because OpenGL ES 1.x do not support them right now.

Apart from that, the demos in the phone and in my computer look pretty similar. For example, the following three images shows the comparison for the SpecialFX, Terrain and Q3Shaders demo:

Special FX:

Terrain:

Q3Shaders:

The images of the right of the comparison are actual screenshots taken on the phone. Note that the lack of shadows in the SpecialFX demo is due to the N95 lacking a stencil buffer, but the OpenGL ES driver does support stencil shadows.

I have developed this as my final project for my degree in Computer Science in the Universidad Carlos III of Madrid, so I am unable to release the source code until I defend it in front of the committee (so as to avoid doubts about me being the developer).

However, I defend on the 8th of January, which is quite soon :)

Anyway, I have upload a sisx file of the SpecialFX demo so that you don't have to just trust my word :) Anyone having a N95 8Gb can give it a try and see it for himself. You can find it here:

Hope you find this interesting! Also, if anyone wants more information or whatever... just ask :)

PS: There is a lot of people I'd like to thank, as without their help this project would have been impossible. These include the people that helped me in this forum, and specially hybrid, which helped me a lot via PMs. Thanks!

Oh cool, seems like you get far better results with some of the examples than the current ogl-es branch. Looking forward to the improvements from your code :D Good luck.

Nice work! Good luck with the committee (although I don't think you will have any trouble).

Wow, that's really cool!

I wanted to give it a try on my N95, but when I follow the given link there's just no file to download...

And I'm also looking forward having a look at the source, once it's possible.

Thanks!

Really cool!
I'd also like to try this out, but mediafire says "The folder you have tried to view is set to private and is not viewable (-422)"

Wow! Thanks you all for your overwhelming response and your good wishes :)

The proper link for downloading the SISX file should be:

http://www.mediafire.com/?g3gohnw2kl0

I hope this one does work :)

If you finally try it let me know what you think :)

I just grabbed the SISX file and installed it in my N95.

Unfortunately, there's just nothing happening when I launch the application. I think it immediately terminates.

Is there any compatibility issue between N95 and N95 8Gb ? Maybe I don't have enough memory for running the app ?

Oh, my! I always forget something. Sorry for the inconveniences.

I forgot to tell the dependencies. As Symbian's native language is not ANSI C++ but Symbian C++, it is needed to install a standard C++ runtime called OpenC++ in order for Irrlicht to run on the phone.

The required SIS files are: Once these are installed, the application should work:
  • Start it.
  • Wait a little (it might take a little to load)
  • In the console, answer if you want real-time shadows by using the keyboard by entering the corresponding letter and then pressing the down direction button, which acts as Enter. By the way, it is irrelevant whether you say you want shadows or not, since the mobile phone won't show them anyway...
  • Then, say that you want to use the OpenGL ES driver.
  • Use the task switcher to go to the main application, where you see the engine run.
  • There is a bug related to OpenC++, so in order to close the application, press the Green button (the one used to make phone calls).
Concerning incompatibilities, as far as I know there shouldn't be any, but since I only own a N95 8Gb I am not sure. I hope you'll tell me :) Finally, memory should not be an issue, at least with this demo. But who knows, Symbian is ... special.

Please, let me know if you finally get the application to run and what you think :)

mm, sorry, which password?

No password should be needed to download any of the files I have uploaded. Also, you don't need Carbide.vs to run the application.
