Hi.
I’m trying to use shader code to animate the shape of a box (using sin and cos)
I can’t get the time uniform to work properly.
I’ve been reading and wondering if the time should be started in javascript inside the “engine.runRenderLoop” function?
Could you please point me in the right direction?

You called your uniform uTime but used time and you are trying to sum a date with numbers 
This should get you unblocked: https://playground.babylonjs.com/#1OH09K#1407
New demo: I created trippy flowers ( using the shader code from the previous example )
New demo: Game of Life
Fully working. Grabbed the algorithm from Dan Shiffman’s The Nature of Code book.
I may update the look and feel… add some shader spice
