.SH DESCRIPTION
.sp
.LP
Each function performs maximum intensity searching.
.sp
.LP
It uses the following equation:
.sp
.in +2
.nf
max[i] = MAX{ rays->results[j][i]
              j = 0, 1, ..., rays->nsteps[i] }
.fi
.in -2

.sp
.LP
where \fBi = 0, 1, ..., rays->nrays - 1\fR.
.SH PARAMETERS
.sp
.LP
The function takes the following arguments:
.sp
.ne 2
.mk
.na
\fB\fImax\fR\fR
.ad
.RS 8n
.rt  
Pointer to an array of \fBrays->nrays\fR maximum values of the samples in each ray.
.RE

.sp
.ne 2
.mk
.na
\fB\fIrays\fR\fR
.ad
.RS 8n
.rt  
Pointer to an \fBmlib_rays\fR structure. The data \fBrays->results\fR 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, \fBrays->results[rays->nsteps[i]][i]\fR on ray \fBi\fR might not equal \fB0\fR.
.RE

.SH RETURN VALUES
.sp
.LP
The function returns \fBMLIB_SUCCESS\fR if successful. Otherwise it returns \fBMLIB_FAILURE\fR.
