TOUR INTO THE PICTURE - PROJ5
COMPUTATIONAL PHOTOGRAPHY
By Begum Gulsoy
This project involves building a 3D scene from a 2D image considering a one-point perspective. First the back wall is selected and then the vanishing point is determined. Using these two pieces of information the image is separated into polygons, each of which is warped into a rectangle which in the end make up the sides of a box. This way a 3D looking scene is constructed from a single image. For this project the programming has been done using interactive data language (IDL), but the images has been warped into a box using MATLAB and the starter code provided.
This is the example picture we were given in class, St.
Jerome by Henry V Steinwick. This is an example
of a painting rendered into a 3D scene. Here is the points taken:
Here is a hallway. This is the image of an actual 3D image and the plainness of it makes it easy to define the vanishing point and the lines. The reason why the final image is so small is because of the parameters used for the size of the walls. I have set it to be close to the back wall, the part with the white rectangle.

Finally, a ceiling example from a cathedralÉ The image doesnŐt have to be of a room all the time. There are a lot of ideas that can be reconstructed using the same idea. Ceilings is one of themÉ The picture is taken from www.flickr.com/photos/cmaughan/206449003
And finally here is a movie:
