How to multiply XMMATRIX and XMVECTOR (DirectX11)?

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.

Cant you define a vector as a 1xN or Nx1 matrix? – Laggard

Answer 1

The function you're looking for is XMVector3Transform (or XMVector4Transform, it depends on what you want).
