This function performs the following operations:

return [Float3](struct_luna_1_1_float3.md)(
    vec.x * mat.r[0].x + vec.y * mat.r[1].x + vec.z * mat.r[2].x,
    vec.x * mat.r[0].y + vec.y * mat.r[1].y + vec.z * mat.r[2].y,
    vec.x * mat.r[0].z + vec.y * mat.r[1].z + vec.z * mat.r[2].z);

Parameters

• in vec

  The vector.

• in mat

  The matrix.

Return value

Returns the result vector.
