So there is this new 3D sculpting and painting application in town, Amorphium, and it seems to have won a ton of awards.
Mind, there are areas that it is weak in, such as in terms of painting, one cannot simply darken or lighten a color too easily. However, the very fact that one can paint directly on an object is a minor miracle in itself.
To date, one generally needs an application to sculpt and an application to paint. Some programs that I use a great deal, such as Ray Dream Studio, allow "painting," but it is a study in frustration. One can really paint directly on a shape made in Amorphium.
And what shapes! There appears to be a limitless number of odd forms that one can sculpt with straightforward ease. Such as the Allosaur skull below, which stems from a photo I took in the museum at Dinosaur National Monument.
And if you have any doubts whatsoever about its three-dimensional aspects, check out the small (for a video) 120K Quicktime video.
Amorphium should hopefully inspire the other 3d applications to try a little harder.
