Multiple Viewpoints

Bird describes Multiple Viewpoints as viewing the same scene/object but from different vantage points. Primarily art had been viewed from a single one point perspective to create a singular 3d view. However with the turn of the 1900's photography challenged the traditional view which led other artist (Cezanne and Picasso) to explore it via painting and other medias.
For my own work I don't generally go to deep into multiple view points in a single work. However if I can place works together or in a triptych that is one means I do use multiple view points. I don't believe I would use multiple viewpoints in a single piece unless it was really needed to convey my message.
