I did another tryptic presentation for one of my classes. This time it had to focus on an artistic element or concept. The one I chose was isometric perspective. It is a form of parallel perspective that has no vanishing points and all of the axes are equally foreshortened. Also in this form of perspective, the scale of an object doesn't change, so an object would appear the same size anywhere in the picture instead of getting smaller with depth. Since there are no vanishing points there is no optical distortion. Isometric perspective is commonly used in traditional Asian art (it was started by ancient Chinese scroll painters), in technical/engineering drawings, and in some video games. I picked images from Hiroshige and M. C. Escher to illustrate the concept.
That's it for now.
