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

You may need to send transposed matrices or switch from matrix*vector to vector*matrix. Output a solid Red colour in your PS to see if projection is correct (unless you're background is Red ).

Yes, it worked, thanks.

Here's the code again:

Code: Select all

   float4 lightPosition; // Object Space
   float3 eyePosition;  // Object space 
   float4x4 WorldViewProj;

void vsmain(float4 Position: POSITION, 
   float3 Normal: NORMAL, 
   float2 Uv: TEXCOORD0,
   float3 Tangent: TEXCOORD1,
   float3 Binormal: TEXCOORD2,

   out float4 oPosition: POSITION, 
   out float2 oUv: TEXCOORD0, 
   out float3 oLightDir: TEXCOORD1, // Tangent Space
   out float3 oEyeDir: TEXCOORD2, // Tangent Space
   out float3 oHalfAngle: TEXCOORD3 // Tangent Space

) 
{  
   oPosition = mul(Position, WorldViewProj); 

   oUv = Uv;
   float3 LightDir = normalize(lightPosition.xyz -  (Position * lightPosition.w));
   float3 EyeDir = eyePosition - Position.xyz; 
    
   float3x3 TBN = float3x3(Tangent, Binormal, Normal); 
    
   // Transformacja do Tangent Space
   LightDir = normalize(mul(TBN, LightDir)); 
   EyeDir = normalize(mul(TBN, EyeDir)); 

   oLightDir = LightDir; 
   oEyeDir = EyeDir; 
   oHalfAngle = normalize(EyeDir + LightDir); 
}

   float3 LightDiffuse;
   sampler2D DecalMap: register(s0);
   sampler2D NormalMap: register(s1);
   sampler2D SpecularMap: register(s2);
   /* Parallax Mapping
   uniform sampler2D HeightMap,*/
   
   

void psmain(float2 Uv: TEXCOORD0,
   float3 LightDir : TEXCOORD1,
   float3 EyeDir : TEXCOORD2,
   float3 HalfAngle : TEXCOORD3,
   out float4 oColor : COLOR)
{
   float2 TexCoord;

   /* Parallax Mapping
   float Height = tex2D (HeightMap, Uv).r;
   Height = Height * 0.04 - 0.02;
   float3 Eye = normalize (EyeDir);
   TexCoord = (Height * Eye.xy) + Uv;
   */
   // else
   TexCoord = Uv;

   float3 Normal = 2.0 * tex2D (NormalMap, TexCoord).rgb - 1.0;
   Normal = normalize (Normal);

   // Œwiat³o rozproszenia
   float3 Diffuse = max (dot (LightDir, Normal), 0.0) * LightDiffuse;
   float3 DecalColor = tex2D (DecalMap, TexCoord).rgb;

   float3 SpecularColor = tex2D(SpecularMap, TexCoord).rgb;

   float Specular = max (dot (HalfAngle, Normal), 0.0);
   Specular = pow (Specular, 8.0);

   oColor = float4 (DecalColor * Diffuse + Specular * SpecularColor, 1.0);
}

The rendermonkey solution: www.orandysoftware.com/user_files/normal.zip

Now comes the pixel bit. In rendermonkey, half of the cube displayed the diffues color like a gradient instead of the textures. I tried loading it in irrlicht and the cube has the specularmap as the diffuse texture, with bumpmap (it seems there's a constant light).

Could someone test to see if it's the shader's problem or the callbacks.

Loads of thanks.

HUm I have 3 five error, 3 conflict between msvprtd.lib and chernolbylShaderFREE.lib , and one error about extern. How can I do ?

[L1zb3th]

I LOVE YOU !

now i can write my desired CG editor and kick in the ass the FxComposer, it's too damned heavy =P
umhhh, i saw that cg.dll compiles the program, but enabling it in Irrlicht ?
umhh, i saw it too complicated, Irrlicht design is not too plugin based...
now i will have my own editor yeahhh

Au Revoir =P

Have You got problem with compile examples? Have You got properly configure Code::Blocks with MS Platform SDK? Maybe You have bad configure project in MS Visual 2005? What Errors You have got in compilation procces?

[BlindSide]

Sounds like he is using "Multi Threaded DLL" or "Multi Threaded" wrongly in the Code Generation settings.

[Steel Style]

Actually I don't work even more on my code before compile yours and I have this error. I use MVS 2005

Erreur 1 error LNK2019: symbole externe non résolu "class irr::IrrlichtDevice * __cdecl irr::createDevice(enum irr::video::E_DRIVER_TYPE,class irr::core::dimension2d<int> const &,unsigned int,bool,bool,bool,class irr::IEventReceiver *,char const *)" (?createDevice@irr@@YAPAVIrrlichtDevice@1@W4E_DRIVER_TYPE@video@1@ABV?$dimension2d@H@core@1@I_N22PAVIEventReceiver@1@PBD@Z) référencé dans la fonction _main main.obj

Wrong Irrlicht.dll

[BlindSide]

Its a linker error, not run-time, and its for an unresolved external (If my spanish is any good). So I think he just forgot to link the irrlicht lib.

Try:

Code: Select all

pragma comment(lib,"irrlicht.lib");

[Steel Style]

So thx, during this thread I download Nvidia Cg, turn the compilation on MultiThread Debug (MTd) then I add the link for the irrlicht lib. And Finally I get Irrlicht 1.4.

@Blindside: Thanks, sometimes easy things are those which are forget . (Bad english) PS :It was French :p

Version 0.5 of Cg Binding for Irrlicht was done! Project has got new name - "IrrCg". With current version You can easy create Cg Shader, similar to create Irrlicht standard shaders per Callback, because it is full integrated with Irrlicht functions:) Now You can use Cg Shaders per Irrlicht Material. You can easy convert HLSL Irrlicht Shaders to Cg Shaders. I update all examples to new interface, so You can see than use Cg in Irrlicht is VERY, VERY EASY! First post update for downloads;) I'm waiting for comments:)

[dlangdev]

cool, i'll give it a spin and report back later.

[christianclavet]

Thanks Nadro. I'll really have to check this!

[FuzzYspo0N]

hey nadro, i updated the link in ur space here,

http://nadro.owned.co.za/IrrCg_v0_5.zip


for anyone here it is too. i HATE the stupid share file services

[Nadro]

Big thanks FuzzYspo0N for upload!
