如何在 CgFX 中使用几何着色器？实际上如何在“技术”中指定几何着色器？

清单如下，顶点和片段着色器编译得很好。但是“NVIDIA FX Composer 2.5”'error C3001 no program defined'在我添加'GeometryProgram'到'technique'.

float4x4 WorldITXf : WorldInverseTranspose;
float4x4 WorldViewProjXf : WorldViewProjection;
float4x4 WorldXf : World;

struct appdata
{
    float4 Position : POSITION;
    float4 Color    : COLOR0;
};

struct vertexOutput
{
    float4 Position : POSITION;
    float4 Color : COLOR0;
};


TRIANGLE void gshader1(AttribArray<float4> pos : POSITION,
                      AttribArray<float4> col : COLOR0)
{
//    some code will be here;
}


vertexOutput vshader1(appdata IN)
{
    vertexOutput OUT;
    float4 Po = float4(IN.Position.xyz,1.0f);
    OUT.Position = mul(WorldViewProjXf, Po);

    OUT.Color = IN.Color;

    return OUT;
}

float4 fshader1(vertexOutput IN) : COLOR
{
    return  IN.Color;
}

technique Tec1 {
    pass p0 {
        GeometryProgram = compile glslg gshader1();
        VertexProgram = compile glslv vshader1();
        FragmentProgram = compile glslf fshader1();
    }
}

解决了。配置文件有问题'glslg'，更改它以'gp4gp'解决问题。
