Point4 operator* ( float  f, const Point4 &  a  )

inline

Remarks

Returns a Point4 that is the specified Point4 multiplied by the specified float.

                                                  {
   return(Point4(a.x*f, a.y*f, a.z*f, a.w*f));
   }

Point4 operator* ( const Point4 &  a, float  f  )

inline

Remarks

Returns a Point4 that is the specified Point4 multiplied by the specified float.

                                                  {
   return(Point4(a.x*f, a.y*f, a.z*f, a.w*f));
   }

Point4 operator/ ( const Point4 &  a, float  f  )

inline

Remarks

Returns a Point4 that is the specified Point4 divided by the specified float.

                                                  {
   DbgAssert(f != 0.0f);
   float invF = 1.0f / f;   // Mimic 2019 behavior
   return(Point4(a.x * invF, a.y * invF, a.z * invF, a.w * invF));
   }

Point4 operator+ ( const Point4 &  a, float  f  )

inline

Remarks

Returns a Point4 that is the specified Point4 with the specified floating point valued added to each component x, y, z and w.

                                                  {
   return(Point4(a.x+f, a.y+f, a.z+f, a.w+f));
   }

float DotProd ( const Point4 &  a, const Point4 &  b  )

inline

                                                       { 
   return(a.x*b.x+a.y*b.y+a.z*b.z+a.w*b.w);  
}
