Hello folks,

This is the first time that i use irrCg,i believe some of us couldn't build one "Hello world"project(I'm the one :( so),after several hours trying i know the problem.If you have build one project and import *.lib files,including head files,still your project doesn't work,and show you many strange problems like

Code: Select all

error LNK2005: "public: __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >(char const *)" (??0?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAE@PBD@Z) already defined in msvcprtd.lib(MSVCP80D.dll)	IrrCg.lib
You'd better regenerate IrrCg.lib and IrrCg.dll by yourselves,the project properties should keep instance with your irrlicht project.
Sorry for my poor English,i hope i've expressed myself clearly.

You can try change "/MD" (Multi-threaded DLL Runtime Library) to "/MT" (Multi-threaded Runtime Library) in project option. It should help.

Great work Nadro! keep it up.

i'm not sure I totally understand this, but in function OnSetConstants you use absolute values
of lightPosition and eyePosition

Code: Select all

        lightPosition = cgGetNamedParameter(Vertex, "lightPosition");
        services->setParameter3f(lightPosition, 0.0f, 0.0f, 120.0f);

        eyePosition = cgGetNamedParameter(Vertex, "eyePosition");
        vector3df CameraPosition = Device->getSceneManager()->getActiveCamera()->getAbsolutePosition();
        services->setParameter3f(eyePosition, CameraPosition.X, CameraPosition.Y, CameraPosition.Z);
but in CG SDK they use "Transform world-space eye and light positions to object-space"

Code: Select all

  /* Transform world-space eye and light positions to .......'s object-space. */
  transform(objSpaceEyePosition, invModelMatrix, eyePosition);
  cgSetParameter3fv(myCgFragmentParam_eyePosition, objSpaceEyePosition);
  transform(objSpaceLightPosition, invModelMatrix, lightPosition);
  cgSetParameter3fv(myCgFragmentParam_lightPosition, objSpaceLightPosition);
What is correct? :roll:

I am take irrCg example "01.BasicLighting", make light moving by adding createFlyCircleAnimator

When objects are allocated near zero point - lighting looks correct,

but if I move all objects (elephant,cube,sphere,camera,light) in a far point (for example 10000,0,10000) - lighting looks strange - as though the light source remained in a zero point

When I have added transform eye and light positions to object-space, lighting has work fine

You should use the latest version of irrCg from SVN.

Hi guys,
I'm a complete noob when it comes to building sources :S
If someone could point me in the right direction,
on how to build IrrCg for openGL in DEV-C++, or code::blocks,
for mingGW :S
I'm completely stuck :(

edit: have got the latest Cg version from Nvidia, and the latest IrrCg from SVN, and the latest Irrlicht. Just for info :P

Is IrrCg still being developed at all? The last check-in was almost half a year ago. Is there any continued development, or is it "done" at 0.8?

Hi,
In last time I was fully switched to OpenGL 3.x + GLSL (integrated with Irrlicht of course), so I have less time for develop irrCg, but project isn't dead, I will try add new features to it in winter holidays.

Sometime ago I worked on game which usage this version of OpenGL 3.x driver:
http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=39585

This is screenshot from an early development version of our (me - programming, Mateusz "Herszt" Bartkowiak - 3d + 2d graphic) game:
Image

Uploaded with ImageShack.us

We used here eg. hardware skinning (based on BlindSide idea) and texture arrays. I will release under Zlib license code (still in alpha version, so have some bugs) of small, pathfinding library which I prepared for this game (it use Navigation Meshes for solve paths).

Game will be not release and I can't say more about title of product, gameplay etc.

Thanks for this great binding Nadro! After a few adapting i got it working with Irrlicht 1.72 and GCC (latest MingW pack).
Thanks again!
