Using 3D-rendered images for scene perception research
Most of the stimuli used in my research are computer-generated, 3D scenes. 3D scenes provide advantages over stimuli traditionally used to study scene perception: They are more visually realistic than line drawings, and they are easier to manipulate than photographs (e.g., the deletion of an object in a photograph requires filling in missing background). Below are some examples of 3D scenes and the types of manipulations they make possible.
A number of 3D artists have been kind enough to donate their models to us. Some of their work is presented in the 3D Scene Gallery.

The two images below demonstrate the types of changes possible using 3D rendered scenes. One of each of the changes listed below occurs between the inital image and the changed image.Changes:
