Revisiting a previous post, sometimes I look at paintings and think wouldn't it be great to fly inside that scene. So, using a section of Visscher's panoramic view of London circa 1616, we put in lines of perspective and traced around the main features.
As the movie above shows you can then create a 3D flythough or indeed a full 3D model. We also put the painting into ActiveWorlds with avatars a while ago and its kind of interesting to not only have 3D art but also see people walking around a picture.
How was it done? Take a look at our follow up post Back to 1999 - Still Love Canoma.
