Ahem, so the problem is that people are limited to just four two-dimensional arrays of R G B and Alpha. It appears that what are needed are more 2D arrays but the image interface is already maxed out with the current implementation, and Alpha is being used by people for undefined purposes because it currently has NO defined purpose.
Expansion is needed for more 2D arrays and more data storage, but this is going to break the ever so simple and clever concept of sculpts as RGB maps. Probably because it is too simple and clever to really be practical in the first place. What image formats allow additional hidden 2D arrays not used for image generation? So we need a Beta channel, on up to Zeta, or whatever. Maybe it's time to drop the "image" concept and go with a new "variable size 1D array of 2D arrays" data format, with each 2D array compressed with lossy wavelet compression where practical. I fully realize I am trodding on Phillip Rosedale's baby here so I don't expect any sort of positive reception of this discusion. :-) - Dale On Sun, May 17, 2009 at 12:05 PM, Dahlia Trimble <[email protected]>wrote: > I've also seen a lot of designers use the alpha channel to mask the entire > bitmap so it doesn't show in the editor and can't be grabbed with a screen > capture > > > On Sun, May 17, 2009 at 10:01 AM, Argent Stonecutter < > [email protected]> wrote: > >> On 2009-05-17, at 00:54, Feilen wrote: >> > That's actually a lot better of an idea, and it would be simple to >> > implement: just use any basic image editor to implement the alpha and >> > remove all of the black space the 3d modeler creates.
