 Reload so that my timer works well Okay, hello, it's three o'clock So I am John Denning. I'm going to be talking about Actually a little bit about some of the work I did during my PhD so I am from Taylor University and in the United States and Just to give you a little bit of backgrounds Presently, I'm an assistant professor in a computer science and engineering department at Taylor University Where I teach computer graphics and core CS courses I got my PhD at Dartmouth College Where in computer science and focusing on computer graphics, but I I have graphics up there, but my approach to graphics is very much from the programmers point of view You know, I worked on poly strips, but I'm not an artist So as you can see here, this is a pretty terrible sculpt and I I'm proud to say I worked very many hours on it But But I'm interested in modeling and sculpting and as a researcher as a scientist Why not study artists and learn to become better? Well, I Started off doing this and I found that there's lots of help out there Just doing a quick YouTube search for a z brush sculpting yields about 75,000 results This is a little bit older. So it might be a little higher than that Glendar sculpting is 114,000 results Maya modeling 180,000 so we have lots and lots of data out there hundreds to thousands of books teaching Modeling we have websites that are dedicated to teach you modeling and sculpting and all the principles This is all great, but the medium that they're working in is is still rather challenging Most video tutorials that I found were really bad a lot of them they rambled they they they trailed off There was lots of details or mess ups and then they would undo Sometimes they were rather hard to follow Document tutorials like in books can be hard to follow if if they have a Couple of snapshots and some textual annotation between to say what they did to modify the mesh Well, if if you weren't in there if it was poorly stage shot you miss some details potentially Also another kind of interesting thing about videos is our time lapses So recording the artist records themselves working and they just plays it back full speed But this is not very helpful for me to learn to become a better artist So this led me down the path of my dissertation The title of its mod flows methods for studying and managing mesh editing workflows So of this of my dissertation there were basically four sections I'm going to just talk about two papers Mesh flow and mesh get hence The rather strange title to my talk which is regular expression if if you're at all familiar with with that So I'll start off by talking about mesh flow Just to kind of practice this all this all this is available on my website I'll post at the very end so if you are interested in the details You can certainly go and check out the papers. I will have some videos all the source code is released GPL So that too is available But this talk since this is blender conference. I didn't know how many developers would be here probably more artists I tried to stick more to lots of pictures And left most of the technical details out So mesh flow is one of the papers Had published at SIGGRAPH 2011 Subtitled interactive visualization of mesh instruction sequences Make sure my time Okay So my son Loves dinosaurs. This is one of his favorite books in this book It shows how to draw different dinosaurs and the one thing that's great about this is it You have this kind of interesting dinosaur down here, but it gives you step-by-step You know how to construct this we're going from one step to another They add in these little details down at the bottom to say okay from the previous picture Here's some here's some features to look for so there's some annotations Kind of help you figure out what change because as you can see when it gets a little more detailed The little additions are kind of hard to find So this is interesting from point of view of a five-year-old child wanting to draw dinosaurs But how does this apply to meshes? I'm going to use this biped as an example. It's it's It's okay, but this would be where we start so one way to To understand how to create this is to watch a video tutorial. I'm not going to play any audio This is Jonathan Williamson a few years ago So in here Jonathan describes the process of creating this this biped And along the process here it he gives details on how to use the blender interface So we go step-by-step. He gives very good
