Question

这里我有一个基于SharpDX的应用程序，它应该使用Computer Shader来模拟粒子。我在Intel HD 3000显卡的Win 8.1计算机上运行它。顺便说一句，SharpDX带有计算机着色器和（或）顶点着色器的样本有fx_4_0或Profile = 10.0等要求。

问题是，当通过Content.Load<Effect>()加载着色器时，它会引发SharpDX.Direct3D11.Device.CreateVertexShader()

的异常

例外情况如下：

[SharpDX.SharpDXException]  {
     SharpDX.SharpDXException: HRESULT: [0x80070057],
     Module: [General], ApiCode: [E_INVALIDARG/Invalid Arguments], 
     Message: The parameter is incorrect.
at SharpDX.Result.CheckError()
at SharpDX.Direct3D11.Device.CreateVertexShader(IntPtr shaderBytecodeRef, PointerSize bytecodeLength, ClassLinkage classLinkageRef, VertexShader vertexShaderOut)
at SharpDX.Direct3D11.VertexShader..ctor(Device device, Byte[] shaderBytecode, ClassLinkage linkage)
at SharpDX.Toolkit.Graphics.EffectPool.GetOrCompileShader(EffectShaderType shaderType, Int32 index, Int32 soRasterizedStream, StreamOutputElement[] soElements, String& profileError)
...
at SharpDX.Toolkit.Content.ContentManager.Load[T](String assetName, Object options)

嗯，我已经看了一会儿，但没有找到一个完整的解释 - 这里到底发生了什么？正如here所述，问题可能在于VertexShader参数，但作为着色器开发中的新手，我无法回避。尽管如此，这是着色器文件：

struct Particle
{
    float3 Position;
    float3 Velocity;
};

StructuredBuffer<Particle> Particles : register(t0);
cbuffer Params : register(b0)
{
    float4x4 View;
    float4x4 Projection;
};

struct VertexInput
{
    uint VertexID : SV_VertexID;
};

struct PixelInput
{
    float4 Position : SV_POSITION; 
};

struct PixelOutput
{
    float4 Color : SV_TARGET0;
};

PixelInput DefaultVS(VertexInput input)
{
    PixelInput output = (PixelInput)0;

    Particle particle = Particles[input.VertexID];

    float4 worldPosition = float4(particle.Position, 1);
    float4 viewPosition = mul(worldPosition, View);
    output.Position = mul(viewPosition, Projection);
    return output;
}

PixelOutput DefaultPS(PixelInput input)
{
    PixelOutput output = (PixelOutput)0;

    output.Color = float4((float3)0.1, 1);

    return output;
}

technique ParticleRender
{
    pass DefaultPass
    {
        Profile = 10.0;
        VertexShader = DefaultVS;
        GeometryShader = 0;
        PixelShader = DefaultPS;
    }
}

我想，问题出在VertexInput结构和uint VertexID : SV_VertexID;，因为在sapmles中，我从来没有遇到过这样的事情。通过vay，应用程序来自，所以你知道俄语，欢迎你去看看原点:)。此外，可以从here

Answer 1

每当您遇到SharpDXException时，请按照"How to debug sharpDX exception"
进行操作

事实证明，尽管得到了DirectX 10.0的支持，但实际上英特尔3000还没有得到ComputeShader的支持

Answer 2

因为我遇到了与monogame类似的错误并尝试加载着色器而偶然发现了这一点。

在我的情况下，此错误与未设置为

的graphicsDevice配置文件有关

HiDef

    graphics = new GraphicsDeviceManager(this);
    graphics.GraphicsProfile = GraphicsProfile.HiDef;
