irrCg v0.8 (Initial) - CgFX (Texture States, MultiPass etc.)

[Nadro]

Built-in Cg support is available in Irrlicht rev4060. Please use it instead of irrCg which is now a deprecated project (we will improve only built-in Cg support).

ORIGINAL VERSION:

IrrCg is Cg Shading Language wrapper for Irrlicht Engine. With Cg You can write one shader and use it for both DirectX and OpenGL, without any modification in shader code. With IrrCg You can easy use Cg shaders in Irrlicht, as Irrlicht Material. You needn't prebuild Irrlicht source! Orginal IrrCg library was build with Irrlicht 1.6, but You can easy prebuild library with Your modified Irrlicht version eg. from SVN.

All features and avaiable functions list are in ReadMe.txt and Documentation.

I get an error: eg.dll cannot be found.

Do I have to compile this in order to use the example?

[Nadro]

eg.dll?? maybe cg.dll? You needn't compile demo (this is only source code of example - CG_Example.exe) Now I've done version 0.2 my binding for OpenGL (acces for textures). I release it after get acces to texture in Direct3D mode. I hope than tomorrow:) In next release I put multitexture example

[Dark_Kilauea]

yea, sorry I meant cg.dll

Gotta love those typos.

[Nadro]

I released version 0.2 of my binding:) In current version You have full acces for textures;) I change files structure in zip archive (now is similar to Irrlicht). I add next example, now for MultiTexturing:) I update first post with link to current version.

Cool. It runs very fast as well. I got 130++ fps with both D3D and OGL on NVidia Geforce fx5200.

Wiki updated. Check it out at "Other Add-ons" and "Shaders" under "Useful Add-ons". I don't know if it is at the right places.

AMAZING. Thank you so much!

I haven't tried it, but if this works good then it should be a great addition to Irrlicht! It should be integrated into the engine right away

Many, many people complain how Irrlicht supports both DirectX and OpenGL but requires seperate shading languages for each one which kind of kills the point. This should solve or greatly alleviate the problem.

EDIT:
Many people dislike RapidShare, so I uploaded it here: http://irrlichtirc.g0dsoft.com/Nadro/CGV02.zip (Direct Download)
(Thanks Rambus!)

Yeah, we could add it (disabled by default, because it would require an additional library to link against), but it would have to be ported to the Irrlicht core. It would need proper integration into the IVideoDriver interface (maybe via createCgShader?) and get a proper cleanup to have all features straightend. But once we have that done we can merge it into the library.
BTW: Is the license ok for Irrlicht?

[Nadro]

Thanks:) and Thanks for upload:) Yes the license is ok for Irrlicht:) This is good idea merge cg binding with Irrlicht:) If Ogre has Cg Irrlicht also has it;)

[BlindSide]

I was wondering if you were thinking of releasing the source, as right now it can only be used on MSVC in windows.

[Nadro]

I very like Linux, so binding must be Cross Platform:) I write port for Linux in this week:) I release source, but now binding is some split with my Game Engine, so I have to prebuild binding as independet library and release it with source:)

[linkoraclehero]

For the record, works on XP64, so go ahead and check that off ;D

[FuzzYspo0N]

@linkoraclehero thats great feedback

@Nadro ,

This is a great implementation , i cant wait to see it in irrlicht or released.

Hope to see it soon :p

[Nadro]

Thanks for checked:) In next release of bindings I add winxp64 as checked and I add support for Linux:)

Nice, I've just started to use linux yesterday.
