Discreet Logic Inc, the Montreal, Canada film and imaging systems and software company, is acquiring Lightscape Technologies, a developer of Windows-based visualization and lighting software tools for design professionals. As part of the deal, Discreet Logic is assuming roughly $4.5m of Lightscape’s debt, of which $3.0m will be handed over upon closing. Debt assumption aside, the rest of the remuneration could add up to as much as $6.8m depending upon whether certain revenue goals are met in calendar 1998 and 1999. Discreet Logic wouldn’t break down specific sales objectives, but did say that existing revenues for Lightscape’s self-named product currently run about $800,000 a quarter, or $3.2m per year. The Lightscape product is used to produce computer-generated environments and images by realistically simulating the behavior of light waves.
