_Xform3dV

  • Article

Multiply a three-dimensional vector by a 3x3 matrix. This intrinsic will load a constant zero into Bank1 floating-point registers (fr12, fr13, fr14, fr15) and Bank0 floating-point register (fr3).

float* _Xform3dV( 
  float* dst, 
  float* src, 
  float* matrix 
);

Parameters

  • dst
    [out] Pointer to a three-dimensional destination vector.
  • src
    [in] Pointer to a three-dimensional source vector.
  • matrix
    [in] Pointer to an array of float values arranged such that the indices of the array are the [row][column] values of the 3x3 matrix.

Return Values

Pointer to the three-dimensional destination vector.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: shintr.h.
