Video 1 of 8 -- Introduction to Wave Cloaking in Blender

This is the first video in a tutorial series on how to create and animate invisibility and wave cloaking in the open-source software Blender. It is assumed the viewer has a basic familiarity of Blender. The video introduces the concept of invisibility and cloaking using methods from the poplar transformation optics technique. It begins by demonstrating a cloaked object with an animation of a wave wrapping around the object as if the object were not there. The video goes on to introduce the basic concepts needed to understand the approach. Topics include Cartesian coordinates, spherical coordinates, converting from one system to the other, and the coordinate transform needed to make a cloak.

I'm not exactly sure what I just learned, or if I'm even legally allowed to have learned it, but god damn I'm sure glad I did! 😮

This is definitely dangerous information. Be careful!

Funnily enough, this is perfect to do procedural eyes or anything symmetric on a sphere without using uvs and avoiding deformations, which was exactly what I was looking for. Wished you would've explained the math a bit more tbh, but hey, you got me doing the math with pencil and paper to understand it better. Except that last equation that I've no idea how you'd come up with. Making pretty patterns with math is my passion xd

I did my best to mention the math, but not go crazy with it for this tutorial series. If you want more details on coordinate transforms, transformation optics, etc., checkout the series of videos under Topic 6 here: empossible.net/academics/21cem/
