Resolution #

setResolution #

setFunction #

Allows you to declare your own GLSL function for usage within Hydra.

Frame rendering #

update #

update is a function that runs every time a frame is rendered. A bit like p5’s draw, only that this one isn’t crutial at all. It can also take in an argument, generally called dt, which contains the amount of time that passed between the previous and current frame.

update( dt )
