Cam2Vista Utility to create camera files in Maya for use with Vista

Some useful tools that could be used for more effective visualzation can be found under "svt_build/tools/" directory 

Change to directory "svt_build/tools/"

   % cd ../svt_build/tools 
   % ls (List the tools available)
formatinfo.o       genraw.o     genrawlarge.o    getopt.o      getopt1.o
meshconvert.o   meshinfo.o  ppmtomesh.o    rawhist.o     rawminmax.o
rawmixer.o        resample.o  rgbtoscalar.o     vcomposite.o

genraw - Creates raw volume files 
   % ./genraw -h (View help page)

   % ./genraw --test mytestfile (creates a file with name mytestfile in current directory)

rawminmax - Finds out the minimum and maximum in a raw volume file
   % ./rawminmax -h (View help page)
   % ./rawminmax --rawtype float myDataFile (Find min and max value for mytestfile we created earlier)

rawhist - Creates a histogram for the data set also finds out min and max in the datset. 
The generated histogram can be utilised for getting better renderings. Histograms only work for scalar dataset
    % ./rawhist -h (View help page)
    % ./rawhist --rawtype float mytestfile >hist_result (This will generate the histogram distribution and will write it to file  hist_result)
    % ./rawhist --rawtype float --logmode myDataFile >hist_log_result 
    (This will generate the histogram distribution in logrithm mode and will write it to file  hist_log_result. 
       This is useful for dataset which have most of data concentrated in the lower region)


rawmixer - Creates a / subsampled / mix of 2 volumes / mix of 3 volumes / mix of 4 volumes /magnitude from 3 volumes/ 
This only work for scalar dataset
   % ./rawmixer -h (View help page)
Subsampling
    % ./rawmixer --rawtype float --dim 100 100 100 --stride 1 2 3  mytestfile  out_subsampled_file 
    This will generate subsampled file skipping 1 float in x, 2floats in y and 3 floats in z so the resulting file would have dimension of 50 x 34 x 25

Mixing volumes to create multivriate volumes
   % ./rawmixer --rawtype float --mix3  infile_1 infile_2 infile_3  out_file 
    This will generate a combined file with all 3 infile variables in one file
Creating magnitude file from three component volumes
  % ./rawmixer --rawtype float --mag3  x_vol_file y_vol_file z_vol_file  out_magnitude_file 
    This will generate magnitude file from three input volumes based on mag=sqrt( X*X + Y*Y + Z*Z)
