I saw a simulation of a black hole on imgur and found it cool enough that even though I know nothing about programming I ended asking for the code which can be found here
Following the guide I installed IntelJ IDEA and created a new project using the address provided, now looking at the code the first line is package org.ygl.openrndr.demos so I tried to do same using the address github.com/ylegall/openrndr-demos but I get:
org.gradle.api.InvalidUserDataException: Included build ‘C:\Users\Usuario\IdeaProjects\openrndr-utils’ does not exist
I also tried copying the Singularity.kt file into the kotlin folder of the openrndr-template but running it there doesn’t work either as it gives a lot of errors most of them saying Unresolved reference.
I googled a little bit those errors and tried looking if someone had asked about them here before but I didn’t found much and also reading the code I don’t get if there is a little bit of real physics hidden on it or if is just only a 100% visual simulation, so I would be very glad if someone could help me.
