insert_pixel()

bool FourierInserter3DMode1::insert_pixel ( const float &  xx, const float &  yy, const float &  zz, const std::complex< float >  dt, const float &  weight = 1.0  )

virtual

Insert a complex pixel [dt[0]+dt[1]i] at (float) coordinate [xx,yy,zz] with weighting into a discrete 3D volume.

Parameters

xx	the floating point x coordinate
yy	the floating point y coordinate
zz	the floating point z coordinate
dt	the complex pixel value (dt[0] is real, dt[1] is imaginary)
weight	the weight to given to this complex pixel

Returns

A boolean that indicates the pixel has been inserted (or not)
