Modern computers come equipped with a powerful GPU (Graphics Processing Unit), which sits idle most of the time. Unless you're playing graphics-intensive 3D games, the power of your GPU remains largely untapped. ImageMachine leverages this power by using Apple's Core Image library. The GPU is put to work in applying a broad library of image filters, ranging from simple color shifts to drastic geometric transformations. ImageMachine is multithreaded, so it will take full use of newer Macs with multiple cores and/or CPUs. ImageMachine's Universal Binary runs natively on both Intel and PPC Macs.
