Shader学习心得（2）:FX的功能之Insert Snippets,以及贴图的shader实现2011-04-18 博客园乌龟_毛驴2.1 为我们的shader增加贴图

Step 1: 在我们的Empty Effect中:

float4x4 WorldViewProj : WorldViewProjection;

下面一行按右键,选择”Insert Snippets”

在右边的框中选择”Texture and Sampler”

在打了一个框的Name上面双击,修改为diffuse,这样所有的”Name”就自动变为了”diffuse”了

Step 2: 添加程序段,使得代码变为

float4x4 WorldViewProj : WorldViewProjection;

texture diffuse <

      string ResourceName = "";//Optional default file name

      string UIName = "diffuse Texture";

      string ResourceType = "2D";

      >;

sampler2D diffuseSampler = sampler_state {

      Texture = <diffuse>;

      MinFilter = Linear;

      MagFilter = Linear;

      MipFilter = Linear;

      AddressU = Wrap;

      AddressV = Wrap;

      };

struct VS_OUTPUT

{

     float4 pos : POSITION;

     float2 tex : TEXCOORD0;

};

VS_OUTPUT mainVS（float4 pos : POSITION,float2 tex : TEXCOORD0）{

     VS_OUTPUT vsOut;

     vsOut.pos = mul（pos,WorldViewProj）;

     vsOut.tex = tex;

     return vsOut;

}

float4 mainPS（float2 tex : TEXCOORD0） : COLOR {

     return tex2D（diffuseSampler, tex）;

}

technique technique0 {

     pass p0 {

              VertexShader = compile vs_3_0 mainVS（）;

              PixelShader = compile ps_3_0 mainPS（）;

     }

}
