Hi @Jon ,

Actually, don’t know which hardware you’re using, but if you’ve a modern graphic card with proper OpenGL support (4.3+) here is s.th. quite nice to study …

It still needs some work, for now basic addition works, im adding basic string reader so you can expand the operations to multiply, divide, etc. The accuracy is currently an issue in some instances, when calculating float values. code structure add pgraphics to shader 2 for each varible to handle floats.// not sure if there is a better alternative canvas draw shader call canvas…

Cheers
