如何将XMMATRIX和XMVECTOR（DirectX11）相乘？

Question

I want to multiply the vector and the matrix. The vector is of XMVECTOR type and the matrix is of XMMATRIX type. I cannot find any function in DirectX SDK to do it. There is XMMatrixMultiply but only for two matrixs, the same for vectors - no (vector, matrix) function.

Answer 1

您正在寻找的功能是XMVector3Transform （或XMVector4Transform ，它取决于您想要的）。
