How to convert HLSL shader code to Assembly shader code

akira32

原始的HLSL Shader Code(AmbientTexture.fx)如下:

//AmbientTexture.fx/////////////////////
float4x4 World : WORLD;float4x4 View;float4x4 Projection;float4 AmbientColor : COLOR0;float4x4 WorldViewProjection : WORLDVIEWPROJECTION;texture Texture;sampler TextureSampler = sampler_state{ texture = <Texture>; magfilter = LINEAR; minfilter = LINEAR; mipfilter = LINEAR; AddressU = mirror; AddressV = mirror;};struct VertexInput{ float4 Position : POSITION; float2 TexCoord : TEXCOORD0;};struct VertexOutput{ float4 Position : POSITION; float2 TexCoord : TEXCOORD0;};VertexOutput vertexShader(VertexInput input){ VertexOutput output; WorldViewProjection = mul(mul(World, View), Projection); output.Position = mul(input.Position, WorldViewProjection); output.TexCoord = input.TexCoord; return( output );}struct PixelInput{ float2 TexCoord : TEXCOORD0; };float4 pixelShader(PixelInput input) : COLOR{ return( tex2D(TextureSampler, input.TexCoord) * AmbientColor);}technique Default{ pass P0 { VertexShader = compile vs_1_1 vertexShader(); PixelShader = compile ps_1_1 pixelShader(); }}

我想要??Q??ssembly Shade Code如下:
???fxc.exe可以?到????等绾蜗履?

//////output.fx///////////////////////

DeALLBugs

There is a great tool called RenderMonkey..........

首先D3DXCompileShaderFromFile
然后D3DXDisassembleShader

NVIDIA的FX Composer2有???功能??
