Animation in Rhino Grasshopper (the first of 2 methods)

in this video i will be describing a simple method for creating real-time animations in grasshopper for rhino seven note that the only difference between rhino seven and rhino six is that rhino seven uses a trigger whereas rhino 6 uses a timer however this should function the same otherwise all right let me delete everything and start at the beginning so if i place a record data device and plug in a value any value in this case 0 as well as a trigger and the trigger can just be plugged straight into the side now i can create a list of numbers that grows with time if i type slash as the shorthand for a panel now i can preview the output and you'll see that if i press play it records the data over and over however another option is to right click on my trigger select interval and choose perhaps 50 milliseconds and now every 50 milliseconds there will be a new data point recorded x will delete the data and this red button will pause the data recorder likewise this will pause the trigger all right if i then plug in a list length node to the output of this data recorder we can preview its output and you see we've just created a number that changes in real time and really that is the only thing you need to make an animation using this method um so with this number we can divide it by say a factor of 6 and now we have a more continual or gradual change and that's nice for creating more steady animations so just to show you how you can make a ball bounce with this i will take the sign and now instead of uh increasing this number is going to oscillate and then if i take the absolute value of this sign output then i will have it bounce off of the zero and now if i change that into a z vector and i move a point based on this vector then this point will bounce and all i have to do is hook up a sphere to this point and now i've created a real-time animation thank you for watching please like and subscribe for more
