A Java rain simulator built with Java Swing (JFrame/JPanel)
This coding practice project is inspired by Coding Challenge video from Daniel Shiffman on The Coding Train.
The core concept is similar, but the implementation differs and was written independently in Java.
The goal remains the same: simulate 3D rainfall in a 2D environment.
Each droplet holds an x, y, z, and len (length) value representing its position in 3D space.
Movement only occurs in the y-axis as gravity is the only force at play here. The speed is influenced by the z-value; the lower the z-value, the faster it falls and vice versa. As z range from 1 to 100, the formula below is used to convert that range to 5 to 2 using linear algebra.
The length of the droplets is also influenced by its z-value. The lower it is, the longer it becomes and vice versa to simulate depth. The formula is also derived using linear algebra.
When a droplet reaches the bottom of the window, it is replaced with a new droplet at the top to simulate continuous rainfall.
