The Tristate Workshop on Imaging and Graphics (TWIG) is an annual workshop for people to exchange ideas on research related to computer graphics. There will be invited talks by professors from nearby universities and a poster session for students to present their latest work. Typically we will try to have one 20-25 minute talk from each attending university. More information will be posted regarding speakers and agendas.
