Differences between HLSL and cgFX

The aim of this page is to convert a HLSL shader in cgFX and vice versa by showing some differences.

FX : vsOut.Pos = mul( float4(pos,1) , Wvp );

cgFX : vsOut.Pos = mul( Wvp, float4(pos,1) );

with :

float4x4 Wvp : WORLDVIEWPROJECTION; float4 Pos : POSITION;

FX : VertexShader = compile vs_1_1 myVS();

FX : PixelShader = compile ps_2_0 myPS();

cgFX : VertexProgram = compile arbvp1 myVS();

cgFX : FragmentProgram = compile arbfp1 myPS();

FX : Texture[0] = NULL;

cgFX : Texture2DEnable[0] = false;

FX : LightEnable[0] = false;

cgFX : LightingEnable = false;

cgFX : LightEnable[0] = false;

FX : MipFilter = LINEAR;

FX : Minfilter = LINEAR;

cgFX : Minfilter = LINEARMIPMAPLINEAR;

FX : float2 f2 = f3; //explicit cast

cgFX : float2 f2 = f3.xy;

with float3 f3;

FX : if (useSpecular) resColor += pow(reflection, specPower/5)*useSpecular*spec;

cgFX : resColor += (useSpecular)? pow(reflection, specPower/5)*spec :0;

FX : float4x4 wit : INV_TWORLD;

cgFX : float4x4 wi : INV_WORLD;

cgFX : static float4x4 wit = transpose(wi);
