Try the same thing with a rectilinear >photo. The original looks wrong to my TV-trained eyes because the optical centre isn't in the middle of the canvas (this isn't actually wrong of course). The right hand column looks flat in the tilted version because it has the different viewpoint treatment in the original - but that looks like a series of mistakes made by the painter/assistant, I would have added another drape to cover up these bits that don't work. Here is another much older perspective that has the same treatment but doesn't show any of these problems: http://bugbear.postle.net/~bruno/misc/durer/durer-st-jerome.jpg http://bugbear.postle.net/~bruno/misc/durer/durer-st-jerome-perspective-cropped.jpg >The "cuboid" is not technically a multi-point perspective, because all >6 faces are viewed from the same point, but it is certainly a multiple >perspective, as each face has a different projection axis.

These are more of Seb's images, they are actually full 360 degree panoramas: http://flickr.com/photos/sbprzd/1288172676/ http://flickr.com/photos/sbprzd/1291236935/ -- Bruno --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
