Hi, everyone. I am starting a new thread as this is a slightly different subject. Despite my research attempts I haven't been able to find a good 3D app to create graphs of color spaces. I am working with two different color guides. Each has a certain number of color tabs or color samples that I wish to plot on a 3D graph. I would like then to fill the area defined by these points (perhaps with transparent walls) to define a volume or color space defined by these color tabs or samples. After I have created these two graphs I plan to compare both by superimposing one over the other to see which of the two color guides is broader in terms of the color space covered by its color tabs or color samples. I hope I am making sense. Is there a good app anyone can recommend that would accomplish this while being simple to use and inexpensive ? Thank you in advance, Joseph.
