This latest version simulates 4.5x faster for sufficiently large simulations. It also fixes a problem where tool path lines were not visible on some graphics cards in Windows.
http://camotics.org/download.htmlThe simulation speed improvements were realized by rearranging the order in which the main algorithm computes the cut surface so that many redundant computations were eliminated. This speed up will not be apparent in short simulations but larger ones, like the Aztec calendar example, should be close to 4.5 times faster.
Thank you to all of those who have recently made donations in support of this project. Have fun!
