Houdini Intro to VEX Programming for Absolute Beginners

In this series of lessons we will learn basics of Python language. We start with installing and setting up Python and Visual Studio Code for programming. Then will cover types of variables in Python then move towards basics of math and concatenating strings. After that towards conditionals in Python then to Arrays, Loops and Functions. We will also do some exercises in Python. After we finish Python we will start doing VEX in Houdini. We will start with basic attributes in VEX to variables then moving to loops and its types such as for, while and do while and foreach loop which is specially used for arrays. Discussing nested loops is also a very important part of this course. We will learn how to add and remove elements from the array using loops. From there we will move to bbox functions and point, detail and HScript functions not to miss out on Sin and Cos functions. distance and xyzdist are also discussed in full detail which are important as well. Functions such as neighbours, neighbours and neighbourcount are also addressed in full detail. We will finish with point finding functions such as pcfind and pcfind radius. I will keep adding more lesson as we progress further. So, stay focused and lets go Code.
