Iam porting an existing project with DirectX 9 to DirectX 11 or 12, I am trying to port the function SetTransform from DirectX 9, there is no reference found in DirectX 11 or 12, please kindly suggest where to find the above function and how to define the above function.

@Balineni Rohith Sai, any update about this question?
There is no replacement for IDirect3DDevice9:SetTransform : https://learn.microsoft.com/en-us/windows/uwp/gaming/feature-mapping
For emulation of fixed-function pipeline, you can see this sample : https://github.com/walbourn/directx-sdk-samples/tree/main/FixedFuncEMUFX11
From https://github.com/walbourn/directx-sdk-samples/blob/main/FixedFuncEMUFX11/Readme.docx:
Fixed-function Transformation Pipeline The Direct3D 9 fixed-function transformation pipeline required 3 matrices to transform the raw points in 3d space into their 2d screen representations. These were the World, View, and Projection matrices. Instead of using SetTransform( D3DTS_WORLD, someMatrix ), we pass the matrices in as effect variables. The shader multiplies the input vertex positions by each of the World, View, and Projection matrices to get the same transformation that would have been produced by the fixed-function pipeline. //output our final position in clipspace float4 worldPos = mul( float4( input.pos, 1 ), g_mWorld ); float4 cameraPos = mul( worldPos, g_mView ); //Save cameraPos for fog calculations output.pos = mul( cameraPos, g_mProj );
