have you checked the following threads > [@3d collision environment (Player versus three point Plane)](https://discourse.processing.org/t/3d-collision-environment-player-versus-three-point-plane/6937): > > Hey forum, first time poster. Here I have made a environment where a player that is shaped like a cylinder can interact with planes defined by 3 points with a few extra player behaviors. All instructions and sources and in the comments. The code could use more tidying up but I cleaned and commented as best I could so without further adieu here’s the stuff : /\*use WASD to move space to jump pivot camera with mouse KEY COMMANDS: 1 : raise a lot of land 2 : raise some land 3 : raise a little… > [@3D collision environment for Android](https://discourse.processing.org/t/3d-collision-environment-for-android/7527): > > Hey yall Not too long ago I made a sketch showcasing a player that can collide with 3-point planes in 3D space. I recently adapted the code for Android and it seems to work pretty nicely so I thought’d I’d post it The code isn’t perfect and its actually runs kinda sluggish to be honest. This is my first time making something for android, not to mention my first time posting something on github (so I’m really hoping I did it right sweat) … --- _[View the full topic](https://discourse.processing.org/t/math-behind-logical-operators-on-3d-boxes-cuboids/32318)._
