I'm looking for a way to have my students visualize RGB code values "natively", not linked to a CIE space of some sort. My goal is to be able to demonstrate the color space sampling of, say, an IT8.7 target such as the one attached (hope it will come through). I found a few neat java applet that interactively allows visualizing movements inside RGB color space, in 3D. But nothing that would allow me to load a text file, that would contains all the RGB data points of an IT8.7 (such as the one attached) and that would allow me to visualize it in 3D space (without the usual CIELab distorsions). Ideally, I would like VRML to show the vertices of the RGB cube along with the positions of my list of data points inside the cube. I believe such an exercice for the students would have a high pedagogical value. A side effect of this application would be to generate what I would consider a more "even" sampling of RGB space for the purpose of developping color scanner targets. Right now, I intend to have the attached IT8.7 file outputted at my local photofinisher on photographic media. Then I should measure all the patches and use that data file in the classroom for the students to build scanner targets. But I know there are big "holes" in the IT8.7 dataset. Best regards and happy holidays! Roger Breton
