The IGG group is the first computer science research group of Strasbourg. Jean-François Dufourd and Jean Françon are at the origin of its creation during the eighties. In 1984, the team gave birth to the Computer Science Research Center (CRI, JE CNRS 91-92) which joined the LSIT (URA CNRS 1207) to form the LSIIT (URA CNRS 1871) in 1994. Twenty years after, in 2013, the LSIIT, by fusion with engineering science laboratories, formed ICube laboratory in the fields of engineering science and computer science.

During the nineties, the research group was already well known for its pioneering research lead by a dozen of teniors. Then, an almost complete renewal of its members occured due to the departure of many researchers. They integrated laboratories in Poitiers (Eric Andrès PR, Yves Bertrand PR, Laurent Fuchs AP, Pascal Lienhardt PR), in Limoges (Guillaume Gilet MC, Djamchid Ghanzanfarpour PR) and Clermont-Ferrand (Jean-Pierre Réveilles PR). The discrete geometry and mathematical morphology thematics of the group have been reassigned to the MIV group of the LSIIT. More recently, Jean-Michel Dischler returned from Limoges to become professor of the group in 2001 and 8 new assistant professors have been integrated during the 2000s; 3/4 of them did not defend their Ph.D. within the LSIIT and come from the LJK (Grenoble), the LIRIS (Lyon) and the INRIA (Nancy, Nice, Orsay).

Since 2010, the strength of the team is stable with no significant changes except the arrival in Strasbourg in 2011 of Stéphane Cotin, DR INRIA leader of the research team INRIA MIMESIS which involved David Cazier promoted full professor in 2014.

From 2011 till 2015, the research group Computer Graphics and Geometry (IGG) was structured around three main topics :
