Project Description

Goal of this thesis was to evaluate the usage of NVIDIA Variable Rate Shading (VRS) for RTX Ray Tracing applications. This Thesis did not use a hybrid deferred renderer/ ray tracer like many papers. Instead, a pure Ray Tracer was implemented. Four methodes of Varing the shading rate were tried:

1. Ray Tracing in a Fragment Shader with VRS enabled
2. Ray Tracing in a Fragment Shader with for-loop instead of VRS as comparison
3. Ray Tracing in Compute Shader with for-loop
4. Ray Tracing in Compute Shader that creates a dispatch buffer for all rays before shading them

Furthermore different luminance based metrics for calculating the shading rate were evaluated.

Project Description

This is project I made for my Bachelor Thesis. It's a relatively new rendering technique in real-time graphics. Standard approaches like Forward or Deferred Rendering shade objects during or after rasterization. Object Space Shading, on the other hand, shades objects before rasterization and stores the results in textures. This has multiple benefits: The biggest advantage is that it enables the render pipeline to reuse shading results. This can mean reusing them between consecutive frames or between multiple cameras in one scene, which can be used to increase performance. Object Space also gets rid of some of the visual artifacts caused by anti-aliasing, which is why similar techniques are already in use for CGI movies.

The Render Pipeline

The Object Space Shading render pipeline goes through multiple stages:

1. First Render Pass: renders the scene's visible UV-coordinates and mip level
2. Tile Mask Compute Shader: determines which parts of the objects are visible and creates a mask
3. OSS Compute Shader: Uses that mask to shade the visible parts of each object in texture space at the correct mip level
4. Second Render Pass: renders the scene with the now shaded texture

Project Description

More and more museums attempt to increase their visitor numbers by combining antique art with modern technology. Doing so offers visitors new ways to interact with the exhibition. This project aims to develop an application that allows the user to digitally repaint a statue in the Museum für Abgüsse Klassischer Bildwerke in Munich. The results are then projected onto the actual statue using projective AR.

Project Description

This project came to life as part of the course "Von der Idee zum Produkt", where we had to develope a game for the generation 50+. My focus were people who do not have much experience with video games yet. I therefore tried to make this game as intuitive as possible. That's why it is intended to be played on tablets or smartphones.

The Game

This game is a puzzlegame where you control a lawnmower that can only drive in one of four directions. The lawnmower only stops once it hits an obstacle or the edge of the level.

In this project I made an AI that can play "The Royal Game of Ur", an 5000 years old mesopotamian game.

My AI, "The King of Ur"

This AI uses a utility function based on 15 weighted factors to find the optimal move. The factor weights were determined by an evolutionary algorithm in a multi-hour test session.

Description

This raytracer is the result of a class held at the Technical University of Denmark. The framework was provided by the teacher, but the rest of the implementation had to be done by the students. The raytracer can handle both simple shapes and triangle meshes. It is not hardware accelerated.

Description

This game was created as contribution to a two week programming competition with the topic "multiplayer games". It's a local multiplayer shooter for 2-4 players in an adorable pixel style. It was created together with Mehmet Guel (@CodeMG) and Christoph Giebenhain (@Christ0). The game features 3 gamemodes, 3 maps and 7 diffrent weapons.

This game is the result of a Master Seminar at TU Munich in which we had to great a game with the theme "destruction". In it you play Godzilla that tries to destroy as much of the city as possible in as little time as possible. The more you destroy the bigger you grow, and the bigger you are the more you can destroy.

• Graphics & Some 3D models
• Procedural Level Generator

Project Description

This is a simple AI for a swarm of boids. Each boids follows three rules:

1. Move away from obstacles
2. Move in the same direction as other boids around you
3. Try to move to the center of the boids around you

This game was created during the 48h Winter Semestergamejam 2019 The them was freeze.
It's a game full of russian stereotypes and memes. The player has to play a series of minigames to catchy russian music, such as a bear fight, putin catapult, a lada race and more. After each game you win vodka which stops you from freezing.

Modlike is a new Rogue-like game where you pass through multiple levels. After each level you may choose a modificator. Modifcators contains both positive and negative effects increasing difficulty and helping you at the same time. Defeat enemies and master enemy units.
This project was created in the 48h Summer Semesteramejam 2020. For the first time, the game jam had to be held virtually, due to the Covid-19 pandemic. The theme was "modification".

This Game is a clone of the app "Flappy Bird", that became popular in 2014. I made this just to prove that this app so easy to programm that even a high schooler could do that in his launch break.

Description

In this epic heavily by Lord of the Rings inspired Jump & Run the protagonist Frobo has to give up his quiet life in the rust hills with Bilbot to destroy the one USB stick. One stick to rule them all. He has to carry it through the sewers of the Moria suburbs and the matrix to finally reach Doom Tower. At least that was the plan. We were young and unexperienced and had more crazy ideas than patience, so the game remains unfinished.

My first big game project. A The Legend of Zelda: A Link to the Past (the in my opinion best Zelda game) style RPG with a zombie as protagonist. Zombies were the big trend of the early 2010s. Sadly my ambitions were too high and my experience too little, so I massivly underestimated the amount of work that goes into a game. Especially when you just started programming, have no experience in graphic or sound design and don't use a game engine. So this game remains in its early prototype phase. But I learned a lot.

This project was part of the highschool informatics class. We tried to make another Zelda: A Link too the past style RPG, this time with a caveman protagonist. This to remains unfinished. We managed to finish most of the mechanics, but underestimated the work that goes into Level Design.
