Do you think it's worth the effort to add a volume intersection report to viewgam? or the gamut volume to tiffgamut -v? (the latter should be no problem, provided that iccgamut and tiffgamut use the same gamut object)
I just aded 3 lines to tifgamut: 557 if (verb) { 558 printf("Total volume of gamut is %f cubic colorspace units\n",gam->volume(gam)); 559 }and "tiffgamut_vol -v -ir ... timage_t_200_sRGB_inters_iC2_r.tif" returned: "Total volume of gamut is 398107.430337 cubic colorspace units"
there's indeed a considerable difference (>5%) to qhull's result:
qhull s FA <timage_t_200_sRGB_inters_iC2_r.points [...] Total volume: 421367.74
so much for "impressive precission" ;-) Klaus
