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

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)
