In this talk, Dr. Wei Xu, an artist, mathematician and computer scientist, talks about why and how we need to add science and math into learning art: [+SM]Art. To improve efficiency in mastering basic drawing skills, he has developed a new shape controlling theory that corresponds with the scientific drawing method, also known as the "ABC (Angle Based Constructive)" method. Unlike with perspective theory, Dr. Xu's solution to constructing shapes is completely in 2D space, making drawing much easier to learn. Recently, his innovative work has been turned into books in multiple languages and presented internationally.
