Tutorial 1/3: How to build a custom Rigid Body Solver from scratch in Houdini in vex. Part 1.

[originally posted on November 21, 2017] I thought to try to contribute to the community with a little seem to know everything about fluid solvers these days, so i decided to cover basics for a bit more obscure, at least for Houdini users, is part one of possible 3 parts.I tried to push everything into one video, but just got too tired. so let’s see how this one goes and if this topic together with this kind of presenting of the material will be accepted by the part covers some common basics and Integration step of RBD solverThe video may be fast paced, so prepare to feel free to pause it to take a longer look at feel comfortable watching the video it’s advised that you: - Are familiar with basics vector and matrix operations - Have basic physics knowledge - Have heard about differential equations - Have heard a bit about finite differences methods I made a little 101 post for introduction into vector-matrix operations, maybe it will help someone examples for the stuff, described in the video can be found here may help understandingsome useful articles (since here we covered basics - all wikipedia):#Conservation#Conservation_of_angular_momentum://://#List_of_3D_inertia_tensors thought i won’t yet publish the whole solver itself, but do it when all 3 parts are done, so the viewer will feel much more confident diving into it’s comments and suggestions are welcome, but i cannot promise to take not of all of them since i’m doing these videos only during free evenings when i’m already half-exhausted.
