Irrlicht Engine

Try this one:
Download the Artoolkit devpack for Dev-C++ from here:
http://pegasus.cc.ucf.edu/~mi872775/files/artoolkit-2.72.1.DevPak
Install the devpack
Use a clean version of IrrAR (with no changes at all)
Open the IrrAR Dev-C++ project file
Change only what is necessary to make the project ...

I managed to compile with MSVC. Everything works, but, when the webcam sees the pattern, she modifies the background, but when she doesn't see, she doesn't modifies.
One idea ?

You need to be more specific to get help.
What exactly do you mean by "modifies the background"?
Are you using irrlicht ...

FreakNigh, I just retook working with your library and I was trying to get it to work with the latest 1.6-SVN, however I got some compile errors because of changes between Irrlicht's 1.4.1 code used for Irrar and the actual version.
Have you or anyone treid updating it?
Irrar compiles and runs ...

Sure loki1985!

Moon position calculation: http://www.phys.uu.nl/~strous/AA/en/reken ...

@devsh: does your moon have correct position (and maybe even appearance) according to date and time? if so, would you share your code?

Last time i checked devsh's code, he uses a full moon image and place it in the opposite direction of the sun (-sun_place.x, -sun_place.y, -sun_place.z).
It is ...

I did not think about the exact way it could work (the truth is i cant..)
I just thought that your idea of using the depth instead of the color might be more accurate.

Anyway, i think we made our point and it is up to DavidJE13 now, because he will write the actual thing. It is still great as is ...

Glad to hear you are thinking of implementing this DavidJE13!

Could be fixed by giving a rough expected position & size, and using this for fine-tuning and obstruction checking.
That is exactly what i was thinking :D

Also, i have to admit that devsh's approach will probably have more accurate ...

I dont really know if that helps but i found this project:
http://blogs.gscept.com/2008/ip16/

It is an hdr implementation using irrlicht 1.4.1 i think and your cg binding + your mrt patch.

There is no source code available but there is a demo with the shaders included..

I think the demo works ...

I really like your class!
Espesially the lens flare effect.
But it is really slow. I get 30 fps when i look to the sun.
I dont know much about shaders but is it possible to do the pixel check for the sun in a pixel shader?
