大家好。我开始重新编码我的引擎以将其转换为 Directx 11。我现在正试图让基础工作正常,但这个错误真的阻止了我。我创建了一个基本着色器,一个法线和视图的简单点积。我让它编译没有错误,但它不工作。它只是使输入网格完全变形。我开始在 vs2012 中调试,发现像素着色器将所有 NaN 作为输入。我附上了两个屏幕和着色器代码,如果有人可以提供任何想法,那将是非常宝贵的。
顶点着色器
//----------------------------------------------------------------------------
// Constant Buffer Variables
//----------------------------------------------------------------------------
cbuffer ConstantBuffer : register( b0 )
{
matrix World;
matrix View;
matrix Projection;
//float3 CameraPos;
float Power;
}
//---------------------------------------------------------------------------
struct VS_INPUT
{
float4 Pos : POSITION;
float3 Normal : NORMAL;
};
struct VS_OUTPUT
{
float4 Pos : SV_POSITION;
float3 Normal : TEXCOORD0;
};
//--------------------------------------------------------------------------
// Vertex Shader
//-------------------------------------------------------------------------------
VS_OUTPUT VS( VS_INPUT input)
{
VS_OUTPUT output = (VS_OUTPUT)0;
output.Pos = mul( input.Pos, World );
output.Pos = mul( output.Pos, View );
output.Pos = mul( output.Pos, Projection );
output.Normal = mul( float4( input.Normal, 1 ), World ).xyz;
//output.wNormal = input.Normal;
return output;
}
这里是像素着色器
//------------------------------------------------------------------------------
// Constant Buffer Variables
//------------------------------------------------------------------------------
cbuffer ConstantBuffer : register( b0 )
{
matrix World;
matrix View;
matrix Projection;
float Power;
}
//------------------------------------------------------------------------------
struct VS_OUTPUT
{
float4 Pos : SV_POSITION;
float3 wNormal : TEXCOORD0;
};
//-----------------------------------------------------------------------------
// Pixel Shader
//-----------------------------------------------------------------------------
float4 PS( VS_OUTPUT input) : SV_Target
{
//return pow(dot(input.wNormal,float3(0,0,0)),Power); // fixed camera, just for now
return float4(0.1,0.6,0.1,1);
}
最后,我为我的着色器创建了一个 xml 文件结构,然后我解析它,不知道它是否相关,但是
