Irrlicht Engine

Yep, everything is ordered now, can put to [SOLVED] !

Thanks to all of you

Ah ah ! I've continued investigations (and put my nose in Makefile files to observe include paths) and i have some more news. Finally, i was not downloading the good versions with my SVN command.

I then downloaded roughly r5136 like this:
wget "http://sourceforge.net/code-snapshots/svn/i/ir ...

No, i repeat i tested with ZIP archives of 1.7.3 (20.02.2012) and 1.6.1 (13.01.2010), and the problem was also happening.

BTW The SVN version of 1.8.3 is probably 1.8.4 before it is released.

The only modification, on the publication day of 1.8.3, was r5136 with the file "changes.txt", so i thought r5136 was the last of 1.8.3.

You have to reset the mask after drawing both eyes! (The mask must be reset before the ...

Great, thank you. I think like you, an include path or something like that, but i don't know how are released the archives. Could just be good if someone can try to reproduce, because i don't see.

I'm ok with this, because i can continue to work with the 1.9 compiled from SVN. But would be better ...

@CuteAlien: When testing other versions of the engine, from DEB, SVN, ZIP / 1.9, 1.8.1, 1.7.3, 1.6.1 ; there's no face to face point of comparison. But for 1.8.3, downloaded from [url=svn://svn.code.sf.net/p/irrlicht/code/trunk@5136]SVN[/url] (r5136) and downloaded from ZIP , i did exaclty the same ...

@hendu: During all my code experiments, i already tried to restore the mask with ECP_ALL before clearing the depth Buffer (after the left eye drawing, and before the right eye drawing), but it was not changing anything.

Also, i've done one more experiment on the ways to install Irrlicht.

If i ...

Here is the result with Irrlicht 1.9 installed from master trunk (29.11.2015):

Some update, because i can't stop until code works ! :mrgreen:

I've downloaded Irrlicht 1.9 master trunk of today (29.11.2015) from:
https://github.com/zaki/irrlicht
then compile it and install it. Then compile my program under Linux... and you know what ? It works ! the problem do not appear ...

I have continued to install other versions of Irrlicht under Linux (by downloading the zip, compiling and installing the lib).
* Irrlicht 1.8.3 (from zip, 13.9.2015) => same problem happens
* Irrlicht 1.8.1 (from deb packages, 17.11.2013) => same problem happens
* Irrlicht 1.7.3 (from zip, 20.02 ...

I've just been downloading, compiling and installing Irrlicht 1.8.3, and then compiling and testing my program. The problem still continues to happen.

Oh! Yes, it is the problem i encounter and which i try to solve for so many hours (days)!

I'm also using Irrlicht 1.8.1 (under Linux Debian Jessie 8.2 stable).

Would then be a bug from 1.8.1? Or as mentionned by Vectrotek, some methods should not be used anymore:

One serious implication of this ...

Ok, thanks mongoose7 ! Good to know. So camera positionning, masks, order of steps, etc. must be ok !!

It is not really my code, but more the one proposed in 2009 by Luke, with small modification to update absolute position:

Thanks for your support Vectrotek!

I've done some more investigations on the direction of my hardware and driver.

Let's recall i'm using a NVIDIA Quadro NVS 3100M (GT218M) under Thinkpad T410 laptop.
This laptop is using NVidia Optimus .

Then i've installed bumblebee ( which is NVIDIA Optimus ...

Next try will be to test the code next week on another PC under Linux with a different graphic card.
