Pixologic claims to be the maker of Sculptris, but actually it had no choice but acquired it in 2010 due to the huge threats from Sculptris, and applied Sculptris' advantages to ZBrush, so as to maintain the market and position of ZBrush. Otherwise, if Sculptris' inventor Tomas Pettersson had chosen to stick to go his own way (although that would have been tough) rather than join into the Pixologic team, then this revolutionary software could have quickly eliminated ZBrush. In other words, it was his own shortcomings that killed his invention, not the competition from Pixologic.
