OpenCL was originally developed by Apple, and aimed to create a common API for parallel programming. It has been used for a wide range of purposes from embedded processors and DSPs up to powerful GPUs. Its popularity is not as high as it used to be, though. Apple has moved to its own Metal...

Thermomechanical Material Point

Computer graphics isn’t the same thing as simulation. It doesn’t have to be accurate, it simply has to look right. What about baking? Watch bread, cookies and pancakes cook in “fake baking” mode. Creating computer graphics of liquids and dust is hard enough, but materials that we cook are very complex. First you have the dough or batter which is a complicated viscoelastic solid. Next you have the effect of heat, which slowly changes the...
