abstract of my masterthesis Hi guys I have to write an english abstract for my masterthesis. It would be nice if someone can check it :) I tried to let it sound smart but I am afraid I am unable to do so in english >..< The use of physic simulations in computer games and virtual reality is a constant trend which lasts years. They allow the development of dynamic virtual worlds, which can change through user interaction. At first there were only the simulation of rigid body possible. Later the increase of computational power enabled the simulation of soft bodies and cloth. However, an essential part of every 3d world is still widely unchangeable - the terrain. This thesis describes the development of a terrain and water simulation for the use in computer games and virtual reality. It discusses not only the simulation itself but also its implementation and optimisation. Furthermore the author examines the advantages, disadvantages and duration differences of the use of the technologies SSE, OpenMP and DirectCompute. With the development of an efficent algorithm and its optimisation it succeeded to create a powerful software, which can simulate the terrain and water surface in an area over the size of 16 square kilometres on a gaming pc in realtime. thank you for your time :)

Welche Websites würdet ihr empfehlen um Deutsch zu lernen? z.B. mit Übungen usw. Damit ich meinen Sprachpartnern etwas empfehlen kann :) Ich selbst hab zwar ein gutes Sprachgefühl, kann aber nie sagen warum etwas richtig ist oder falsch ist ;)

seond notebook entry and first blog entry. My programming history ;) Hi guys. I wrote in my last notebook entry that I was planning to create a blog and I finally found time to post my first entry. The web address is http://devluz.blogspot.de/. If you want to look at my pictures or videos you have to use the blog. Corrections are very appreciated.:) Here is the text: Hello and welcome to my blog :) In my first post in this blog I want to tell you how I came to programming and what I learned in the last years during my study in applied computer science. The main purpose of this blog is to improve my english but I hope it isn't too boring for the readers out there. Later I will post some details on gaming technology and how games developers trick you and your eyes with cheap graphic effects :p but in this first post I will tell you about my programming history. :) My family got their first PC when I was 6 years old. I problably even wrote my first words in a MSDOS console thus I got my first programming experience with a little bit of shell scripting. With 14 I bought a HTML and a JavaScript book and began to learn my first peaces of programming. Around the same age I decided that I want to become a computer specialist and only two years later I started an apprenticeship as one :) . There I learned my first real programming language: c++ but sadly only very basic things. Finally in my last year as apprentice I learned java by myself and got really really obsessed with programming of all kinds especially games :) At first I wrote quite simple games like pong, chess and a chat to learn more about network programming. However I lost quickly my motivation to continue after I had started my study in applied computer science and had had to learn a lot.^^ In my first semester vacation I began to learn more about 3D graphics and wrote a 3D tool to visualize data about the density of pills. It was just a little exercise but the results looked kind of cool :) Later I learned more about computer graphics at the university. There I developed my first 3D game spacearena with some of my fellow students. We wrote it from scatch in only three or four weeks. The player has to shoot all astroids on the map as quick as possible. The time needed was shown in a ranking on my server. Sadly the webversion doesn't work anymore because we used a 3D library that is obsolete now. ... Notebook entry is full :s It seems I wrote to much^^

My first notebook entry :) What should I write about? I spent some days thinking about topics I should write about in my notebook. The hard part in learning for me isn't usually the learning itself, but to find and keep the motivation for a longer time. Therefore I decided to write about my studies and my private projects to improve my skills. It may seem weird that I see this topic as motivating but I have been very lucky to find a discipline which I really love. I hope it motivates others to correct my entries, too. :) I will combine the notbook entries with a blog so every entry here will be a entry in my blog, too. I hope it will not only help myself but also motivate other people to learn more about computer science and the technology behind gaming because it is an very interesting topic that is often misunderstood ;) . At first I will write about some of my early projects to learn programming in java and 3D computer graphics. That means some simple game projects like pong and chess in 2D and a 3D tool to visualize point clouds. Later I want to write about more recent projects of mine and show you how game developer fool you so you think games would be much more realistic than they actually are ;). Basically the topics will be about gaming, programming, physics and robotics and also about every combination of these topics. ;o) I hope it will be interesting for you. Greetings Luz

How do I have to change the sentence if I replace had with got? Example (from the book): The director >had< the technicians install robots on the production line. The director >got< them >to< install robots on the production line. Does got online work with Personal pronouns and had online work without? (because every example with in my book has only this sentence structures. Are the following sentences correct? The director >had< them install robots on the production line. The director >got< the technicians >to< install robots on the production line. Thank you for your help :)
