mediaLib Library Functions      mlibVolumeFindMaxBMaskU8(3MLIB)



NAME
     mlibVolumeFindMaxBMaskU8,  mlibVolumeFindMaxBMaskS16   -
     maximum intensity searching

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlibstatus mlibVolumeFindMaxBMaskU8(mlibu8 *max,
          const mlibrays *rays, const mlibu8 *bmask);


     mlibstatus mlibVolumeFindMaxBMaskS16(mlibs16 *max,
          const mlibrays *rays, const mlibu8 *bmask);


DESCRIPTION
     Each function performs maximum intensity searching.


     It uses the following equation:

       max[i] = MAX{ rays->results[j][i]
                     j = 0, 1, ..., rays->nsteps[i]; bmask[j] = 1 }



     where i = 0, 1, ..., rays->nrays - 1.

PARAMETERS
     The function takes the following arguments:

     max      Pointer to an array of rays->nrays  maximum  values
              of the samples in each ray.


     rays     Pointer to an mlibrays structure. The  data  rays-
              >results are organized with ray number (rather than
              ray step) varying fastest. Ray number and ray  step
              are  the  output  of the ray casting functions. The
              data might have values beyond the maximum step on a
              ray. For example, rays->results[rays->nsteps[i][i]
              on ray i might not equal 0.


     bmask    Pointer to a 1-bit mask array. Eight mask bits  are
              packed  into  one byte. A 1 corresponds to the data
              in the step to be considered.
