Sometimes… but, today, it seems to be working with me. I made the mistake of “downloading” some models of neurons for our latest show “The Brain Fitness Program.” And after playing around with those very capable little models, I discovered that the kind of animation I needed to do would require a bit more flexibility than those models could provide. Rather than trying to tinker with that and risk blowing it all up… I figured, “Heck, why not reinvent the wheel?”
This is the kind of thinking that usually gets you into trouble. However, after a few cautious experiments, I found that I could place a glowing orb in a semi-transparent rough cell body…and voila, nucleus! And then, a few more shaders, and the neuron axon looked kind of electron microscopic and bumpy. And with this, I could actually make my pre-synaptic neuron ends partially transparent and put little baubles inside them to be neurotransmitter stand-ins. And the coup de grace? Finally figuring out how to make a little pulsing trace of volumetric light to show the nerve impulse. And the result:
