He holds a Ph.D. in computer science from theUniversity of California, Davis and a master's degree in mathematics fromVirginia Tech, where he also competed in cross-country and track and field.
Lengyel is an expert in font rendering technology for 3D applications and is the inventor of the Slug font rendering algorithm, which allows glyphs to be rendered directly from outline data on theGPU with full resolution independence.[1] Lengyel is also the inventor of theTransvoxel algorithm, which is used to seamlessly join multiresolution voxel data at boundaries between different levels of detail that have been triangulated with theMarching cubes algorithm.[2]
Among his many written contributions to the field of game development, Lengyel is the author of the four-volume book seriesFoundations of Game Engine Development. The first volume,[3] covering the mathematics of game engines, was published in 2016 and is now known for its unique treatment ofGrassmann algebra. The second volume,[4] covering a wide range of rendering topics, was published in 2019. Lengyel is also the author of the textbookMathematics for 3D Game Programming and Computer Graphics[5] and the editor for the three-volumeGame Engine Gems book series.[6][7][8]
Lengyel founded Terathon Software in 2000 and is currently President and Chief Technology Officer at the company, where he leads development of theC4 Engine. He has previously worked in the advanced technology group atNaughty Dog, and before that was the lead programmer for the fifth installment ofSierra's popular RPG adventure seriesQuest for Glory. In addition to theC4 Engine, Lengyel is the creator of theOpen Data Description Language (OpenDDL) and theOpen Game Engine Exchange (OpenGEX) file format.[9]
Lengyel is originally fromReynoldsburg, Ohio, but now lives inLincoln, California. He is a cousin of current Ohioan and "Evolution of Dance" creatorJudson Laipply.
