在 DirectX11 顶点着色器和像素着色器之间切换

Question

所以我一直在关注 Frank Luna 书中的教程“使用 DirectX11 进行 3D 游戏编程”，并且一直在研究 Sky-box。这个天空盒渲染正确除了需要对纹理进行小的调整。我为天空盒创建了一个单独的顶点和像素着色器，因为它不需要在 .fx 文件中做太多工作。当我绘制我的对象时，它们都会绘制，但是当我使用正常工作的普通顶点和像素着色器时，我的对象显示为黑色（我认为它们无法从它们的着色器中获取颜色）。

_pImmediateContext->RSSetState(_solidFrame);
_pImmediateContext->VSSetShader(_pSkyVertexShader, nullptr, 0);
_pImmediateContext->PSSetShaderResources(3, 1, &_pTextureSkyMap);
_pImmediateContext->PSSetShaderResources(0, 1, &_pTextureRV);
_pImmediateContext->PSSetShaderResources(1, 1, &_pSpecTextureRV);
_pImmediateContext->PSSetShaderResources(2, 1, &_pNormTextureRV);
_pImmediateContext->PSSetSamplers(0, 1, &_pSamplerLinear);
_pImmediateContext->PSSetShader(_pSkyPixelShader, nullptr, 0);

//Imported Sky
world = XMLoadFloat4x4(&_sky.GetWorld());
cb.mWorld = XMMatrixTranspose(world);
_pImmediateContext->UpdateSubresource(_pConstantBuffer, 0, nullptr, &cb, 0, 0); //Copies the constant buffer to the shaders.
//Draw the Pitch
_sky.Draw(_pd3dDevice, _pImmediateContext);

_pImmediateContext->VSSetShader(_pVertexShader, nullptr, 0);
_pImmediateContext->VSSetConstantBuffers(0, 1, &_pConstantBuffer);
_pImmediateContext->PSSetConstantBuffers(0, 1, &_pConstantBuffer);
_pImmediateContext->PSSetShaderResources(0, 1, &_pTextureMetalRV);
_pImmediateContext->PSSetShaderResources(1, 1, &_pSpecTextureRV);
_pImmediateContext->PSSetShaderResources(2, 1, &_pNormTextureRV);
_pImmediateContext->PSSetSamplers(0, 1, &_pSamplerLinear);
_pImmediateContext->PSSetShader(_pPixelShader, nullptr, 0);

//Floor
// Render opaque objects //
// Set vertex buffer for the Floor
_pImmediateContext->IASetVertexBuffers(0, 1, &_pVertexBufferFloor, &stride, &offset);
// Set index buffer
_pImmediateContext->IASetIndexBuffer(_pIndexBufferFloor, DXGI_FORMAT_R16_UINT, 0);
world = XMLoadFloat4x4(&_worldFloor);
cb.mWorld = XMMatrixTranspose(world);
_pImmediateContext->UpdateSubresource(_pConstantBuffer, 0, nullptr, &cb, 0, 0); //Copies the constant buffer to the shaders.
_pImmediateContext->DrawIndexed(96, 0, 0);

//Imported Pitch
world = XMLoadFloat4x4(&_pitch.GetWorld());
cb.mWorld = XMMatrixTranspose(world);
_pImmediateContext->UpdateSubresource(_pConstantBuffer, 0, nullptr, &cb, 0, 0); //Copies the constant buffer to the shaders.
//Draw the Pitch
_pitch.Draw(_pd3dDevice, _pImmediateContext);

_pImmediateContext->PSSetShaderResources(0, 1, &_pTextureMetalRV);
_pImmediateContext->PSSetShaderResources(1, 1, &_pSpecTextureMetalRV);
_pImmediateContext->PSSetShaderResources(2, 1, &_pNormTextureMetalRV);

我是否遗漏了一行代码来清除更改着色器和不使用错误数据之间的某些内容？？

Answer 1

我没有注意到对 .fx 文件进行小的编辑时出现了问题。现在通过还原该文件来修复。
