Here is a rather comprehensive tutorial on setting up the HM-10 Bluetooth module for use between an Arduino and an Android app made with MIT App Inventor using Bluetooth BLE. It can really help you understand the fundamentals of Bluetooth.
Procedural Terrain – Diamond Square Algorithm (Java)
Hello everyone,
I created an implementation of the Diamond Square Algorithm which is a method for developing procedurally generated terrain that can be used for video games or computer graphics. In this implementation of the algorithm I used java to generate a procedural square terrain with a variable amount of subdivisions. I then exported the vertex information of the terrain as a .obj file which can be used in almost any 3D editor.
Here is a link to the main code for the implementation.
If that does not work here are images of the main functions:
Part 1 Part 2 Part 3 Part 4 Part 5 Part 6 Part 7
Here are some example procedural terrains I generated from the code.
