1. ## Maths & Programming in Houdini as an FX-TD

Hello guys, I'm currently a Computer Graphics bachelor student, we are learning CGI but also, Mathematics, Python and C++ some people are very proficient with all these 3 while I'm very proficient in CG but not very strong in these field. I'm very motivated to learn and go deep into these 3 field but I would also like to be efficient in the way I will learn it. ( learning all the mathematics is unfortunately not possible. ) So I would like to know what is your best advice to start learning mathematics and programming to become an FX-TD, based on your own experience or on some experience from other people? Do FX-TD always use programming in the task they are asked for? Any advice, any experience is very much welcome and it would help me a lot.
2. ## 3D Convolution

Testing out an idea I had. Chop up A, Chop up B. Use the parts of B that are like A to rebuild A using only parts from B. 3D convolution. In audio the technique is called Convolution reverb. In Machine learning the technique is used to teach the computer to recognize objects. Here in my test it's used to glue a bunch of soggy corn flakes to the poor beleaguered Stanford terra cotta bunny. More explanation and demo videos to come. Questions? Comments? Has someone already done this but better?
3. ## Mobius transformations

I'd like to know if anyone has done something like this in Houdini? Applying a mobius transformation to a simple grid for example? The formula looks straight forward....if you can read maths, which I can't! http://www.math.ucla.edu/~mwilliams/complex.html I've been looking around for code examples of a Mobius transformation but haven't found any good examples which I could reproduce in Houdini. It would be interesting to hear if any one has done something like this, or can translate the equation into readable code for a non-mathematician
