 present you My way being on my my time being a student in Germany at two institutions called the Ohm so the Technische Hochschule Nürnberg Georg Simon Ohm Just the ohm and the Friedrich Alexander Universität erlang in Nürnberg, which is abbreviated as FAU So this is the basic content of my presentation But first of course, I would like to introduce myself. So my name is Adam Kalisch I was born and raised in Nürnberg. That's in Germany and I was always fascinated by creating media. So I started an apprenticeship as an AV media designer And I also started to use or to think our 3d graphics pretty early by using cinema 4d But now I switched completely to blender Basically the the reason was the introduction of 2.5. So I'm just a blender guy right now Yeah, after my apprenticeship I started to study media engineering at the ohm in Nürnberg and Currently I'm studying computer science. I'm doing my master's degree in Erlangen Yeah, so just to tell you where Nürnberg is if you want to visit Nürnberg You have you first have to go to Europe and in Europe you have to go to Germany and in Germany you have in the southern part you have the state of Bavaria and in Bavaria you have Franconia, which is in the northern part of Bavaria and in Franconia Pretty much in the center or in the middle of Franconia. You have Nuremberg and above Nuremberg that's Erlangen and In Nuremberg there is the Technische Hochschule Nürnberg, Georg Simon Ohm and in Erlangen That's the FAU Friedrich Alexander University Erlangen Nürnberg a Few words about Nuremberg Nuremberg is a very beautiful city. It has quite a lot of medieval style buildings. You can see But it also has like it played a major role in the Second World War So if you want to find out more about history, then you I invite you to visit Nuremberg Yeah, just to get more knowledge about Nuremberg and about Erlangen. Erlangen is basically Is basically known for two main things first of all for its students because there's the FAU the university and and also for beer because There is the Bergkirchwein in Erlangen, which you could imagine being like a smaller version of the Oktoberfest in case you know it Yeah, but let's go back to Nuremberg and Let's take a look at the Technische Hochschule Nürnberg Georg Simon Ohm Or maybe it's easier to pronounce as the NIT the Nuremberg Institute of Technology and The NIT has various courses to offer There are various faculties and studies and if you would expect somewhere to find Blender then probably By studying design But actually this is not really the truth because the designers Do not really use Blender. I did some research. Why? Why the why it is like that, so I was told that The designers consider Blender not to be used really commercially neither by the industry nor by Yeah, marketing companies like agencies for example, and yeah, I think well, I have a different opinion on that, but I Think that everyone has its own opinion. Then there is media engineering the study course media engineering And this is where the tech guys are so and if you study media engineering, it's very likely that you will find some Parts that use Blender during your study during your curriculum and I want to Introduce it a little bit more so if you study media engineering you can attend the computer graphics lecture in the third semester and Then computer graphics you basically learn how to program in C++ and to use the open GL API to draw graphics on on the computer screen and There was since the beginning there was a small Blender part, but it was voluntary and Here are some examples of three groups that Did this Blender part? We'll just play them here. Yeah, and I There was a time where I started to to study Media engineering and I looked at those examples at those results and I thought well I think Blender should be capable of creating much more sophisticated results I also have to say that the third semester in media engineering is one of the rather difficult ones and There was actually no real guidance in in how to use Blender whatsoever And that's why I contacted my professors Dr. Stefan Röthke and dr. Matthias Hopf and asked them if I If it would be okay if I could do some tutoring in Blender like help the students to create those animations and luckily they agreed on that and they were very supportive from the beginning on and Gave me the opportunity to just Yeah teach or help the students with their problems when they Hit an obstacle for example, they could overcome it somehow With my help or with the help with tutorials I could maybe Know on the internet and those are the results where I was the first time Employed as a tutor and it's For one, it's nice that you can if people get the right guidance on how to use the software You can see that the results they create are Much more they have much more life in it and you can really push the The talent also I'm also very grateful to my professors that they gave me the opportunity to just teach Blender and They really see the value that brand Blender brings to To teaching computer graphics in general and the concepts also By the way, all of these slides are available online. I will not show everything just due to the time constraint I have But you can watch them online if you want and now in the current winter term There's something new we managed to integrate Blender much more tightly into the computer graphics lecture Since this winter term I'm an assistant professor for the computer graphics lecture and there is now a 25 percent mandatory Blender part in the computer graphics lecture and Yeah students just learn how to really apply those theoretical concepts By using Blender and they can try out different things, which is kind of amazing Yeah, then in the fifth semester when you are studying media engineering you will have to complete a project and one project proposal written there on the wall was Blender render farm and I thought well this sounds like the best idea to participate in and That's why I Participate in this project together with some other people in the team. We had to create a render farm Of course many of you might know that Blender already has a render farm integrated But the solution we had to create was a kind of a generic solution So we also wanted to support other software packages not only Blender, but Our focus was Blender in the beginning and to create something that maybe also the designers could use so we have created two Yeah, two programs and The first one being the soft server and the other one being the soft client which you just When you boot up your computer, you just start this software on your on your computers and they automatically do the communication and Yeah, if you want to render a blender file You just drag it into the software and then you can start rendering it on the on the network and Yeah This this code Unfortunately, this software did not really reach the production ready state But I have released it as open source on the web so that you can try it out in case you want to To create your own render farm or just use it For our purposes it was okay, but of course there's still you can improve still a lot you can improve Then in the sixth semester in media engineering you have to create again a project and in our case it was a project to create visualization for a famous watchmaker called Peter Hinline who Was said to have created the first pocket watch the so-called Peter Hinline pocket watch and Our task was to create two animations one animation explaining like the The how the clock works or the watch works I mean and the other one being to show the critical parts of of the clock why it Maybe wouldn't have worked Like like it was set in the reality so We started by getting some drawings of the clock like the disassembled clock We also had a CT scan And we also later had photographs of the of the clock so the the museum Which we did the animation for they took the clock and the watch and reassemble disassembled it and Took photographs of the individual parts so that it was easier for us to to model them Now I will also just quickly show you the the animations can also watch them on YouTube But on the left hand side you see the the movie that Explains like the how does the function the the the watch work in detail and the right The movie on the right hand side here shows the critical parts Yeah, you will also find the links on the on the slides Of course, we had some challenges doing those animations first of all being we Managed to get the CT scan into blender but only the low resolution version so the one with the 18 with 18 million vertices and Blender started to get like To lag a bit But you with the help of the VBOs the vertex buffer objects. It was possible to navigate at least the viewport quite smoothly The other challenge we had was to wind up a few z-chain We considered to use Physics simulations for that, but it turned out that this didn't work so great We then used constraints to wind up the the chain But it also well it didn't look really really good to be honest and Another chain challenge we had was to fade in and out of certain components of the watch we wanted to show just certain parts so we decided to animate the material transparency which Unfortunately did result in something that we didn't really see the transparency in the viewport But I think that many of those problems are solved with a new real-time Render engine in the viewport like the EV development and should be Yeah, solved in the future, which I find is a very great addition to Blender now at the end of the media during curriculum I had to create my bachelor thesis and Of course, I love computer graphics. I love Blender. I also love 3d scanning So I wanted to combine those those topics with each other But unfortunately in turn out it turned out that a blender does not Or is not capable of displaying colored point clouds in the viewport And of course if you work with laser scanner data, you want to display this this those point clouds and So I had to find a way how to get the laser scan into into Blender and that's why I created a software Which Works like this. So you have your your lay your laser scan, which is panorama around the scan location then I Take every point. I project it onto 2d space. You can see it here on the left hand side. There's a depth image of the Yeah, the final depth image of the point cloud. So you just create this 2d panorama image and Then you take this 2d panorama image wrap it around a 3d sphere and you get something you can see on the right hand side here and Then you can take the sphere and distort it given the depth information from the panorama image and then it looks like this so This is what I what I chose to get my my point cloud into Blender But I mean it's not the best way to get the point cloud into Blender It should it would be better to just have the point cloud support But as far as I looked up on or I asked on Blender artists, it is not That easy because the underlying data structures in Blender are not really suited for displaying colored point clouds Yeah, and now about the FAU you may know the FAU from this project face to face. I will just play part of it where you Have a webcam this webcam can record your face and You have a video of an actor or a politician and then your facial expression is transferred onto this video and you can Yeah, just fake Real video recordings, which is kind of scary, but it also shows the the power of 3d graphics, of course Okay And There are also some famous people which you might know or you at least you use their features They implemented into Blender. There's one. There's Niels Thurai who that is PhD thesis on fluid simulation and Participated in the Google summer of code 2005 and implemented the first liquid solver into Blender Which is a very nice thing and I talked to him and he said that doing this project with implementing into Blender was a very good idea and There's also Matthias Niesner who did his PhD on the efficient subdivision of surfaces And this is now called open-subtive and we also have it in Blender, of course And then there's Pascal Schoen who's also in the audience here right now and he implemented the principle BSDF and Yeah, that's something almost everyone uses as far as I saw it so far and even I use it It's just a very nice new shade that we have there At the FAU Blender is also being taught And that's called the Blender seminar. So students can participate in the Blender seminar It's a three-week course where in the first two weeks in the first two weeks they learn how to use Blender how to apply their The skills by modeling and by texturing and so on and in the last week they create animations with Blender and I'm really running out of time So I will just Again, I have this videos on the slides to the presentation and they are also online You can just watch them with sound also. I will just continue and end my presentation on time Of course now after the Blender conference, I have to create my master thesis and naturally I'm looking into creating and using Blender again but the topic is 3d reconstruction from video and and There is still this problem. You might remember with the point clouds and the 3d reconstruction just produces point clouds in the beginning and we need to have a way or we just require Blender to just be capable to Display those point clouds I don't know how it turns out, but of course when I gain Enough experience. I will try to implement it into Blender, but I cannot promise anything, but that's like the big goal To understand it. I mean we have a motion tracker after all so it should be possible. I think now as the last Slide I want to invite you to a new room book in case you you come to new room book be sure to Come to the Blender user group in in your own book. It's called the new room bug and Yeah, also be sure to check out the sausages you can see on the screen here, which was obviously rendered in cycles Those sausages are called trying Vecla. So just check them out and yeah, I Want to say a big. Thank you. Thank you Blender community. Thank you Blender developers. Thank you conference team For yeah doing this this conference and Blender after all and thank you for listening, of course
