Peter Helmut Wohlfarth

Hi, I'm Peter Wohlfarth.

I had a wonderful childhood in the city of Leipzig (Germany) and developed an interest in the world at an early age, wondering how I could turn my plans into reality.

This website is intended to represent me and also serve as part of my application (for an internship).

But it should also function as a data center for my games and applications.

At age 10, I wrote my first line of code, and today I already have my own 3D engine (throught OpenGL) and my own programming language... Jigsaw Script.

I have worked with the following programming languages and systems:

    App-Development:
  • The triple pack: HTML, JS, CSS
  • Java
  • Kotlin (Android)
    • Game-Development:
  • OpenGL, 3D-Grafic-Computing (through LWJGL a Javalibrary)
  • C#
    • Hardware-Development:
  • Python
  • C++
    • My-Own-Language-Development:
  • Compiling (Tokenizing, Parser), Interpreter...

You can access the respective subpages in the images below and the headline above.

As just mentioned, this page is also aimed at the people I want to do my internship with. So now I want to talk about my internship and give you all the information.

My internship at Appsfactory

At my school, I can do a two-week (22.06.2026 - 02.07.2026) internship wherever I want. So, of course, I wanted to apply for something that suits me,
that I'm good at, and that I enjoy, which is software development. First of all, I wanted to apply to Mojang,
because Minecraft (which is from Mojang) is my favorite game and I have a lot of experience in this area (3D game development).
Unfortunately, Mojang is no longer accepting interns, so I had to change my plan. So I looked around and found what I was looking for.
Namely, you! I have always enjoyed developing apps (since I started programming) and why not do an internship with you?
In addition, your location in Leipzig is perfect, as I live in Leipzig myself. So now I am asking you if this is possible or if there are any problems.
I look forward to your response. Thank you and enjoy viewing my own website (which I developed in HTML/CSS/JS).

I love it to coded with OpenGL (through LWJGL) because I'm intrested how 3D-Graphics works. Yes and now I know how... With Triangles, here my own litle Simulation:

It's so interesting how the shaders works and how the 3D-Vertex will be transformet to a 2D display-coords. And I looked at how the vertex shader works mathematically.

I mean, it's just fantastic that the MVP-matrix converts the vertex vector to a clip space.My projects are simple, except for one... Minecraft coding by my self. But that means that I should have a lot of interesting tasks ahead of me. But look under sektion "Projects" for more information about my projects.

My Ideas for the futur with OpenGL or Vulkan are I mean interesting. My plan is my own game-engine with multiplayer and my own programming language... JSS (The Graphic on the bottom), voxel-game like Minecraft but with smaller blocks (/16) the voxels and a randomized infinity world with kinetic energy for machines.
and hardware-simulation-engine (Like redstone but with logical-gates, like OR, XOR, AND, NOT)
