NancyGormezano Posted May 6, 2015 Share Posted May 6, 2015 (edited) Although a little off topic, the folks at DIsney have an interesting paper that (very loosely) relates to this: http://www.disneyresearch.com/wp-content/uploads/Sketch-Based-Generation-and-Editing-of-Quad-Meshes-Paper.pdf oh that is very INTERESTING - a brief skimming of the images shows 5 pt patches ! I did not read the document for comprehension, so I am not sure of the details they are proposing. But I like a sketch based concept! (Seems to me some past Hash programmers went to Disney 6? years ago...hmmmm...wondering if Disney has been/is reading some of Martins papers and expanding? EDIT: nope, no references to Hash, but they do reference Catmull-Clark subdiv alg., btw, Ed Catmull was Martin's PHD advisor) Edited May 6, 2015 by NancyGormezano Quote Link to comment Share on other sites More sharing options...
nemyax Posted May 6, 2015 Share Posted May 6, 2015 Check out this experimental program from a couple of years ago: http://www.gunayorbay.com/tutorial/ It's useless for content creation, because it doesn't export anything, but it's a nifty proof of concept. This really should move to a separate topic. Quote Link to comment Share on other sites More sharing options...

nemyax Posted May 6, 2015 Share Posted May 6, 2015 Some practical 3D sketching techniques and heavy-duty surfacing (including a complete violin modelling session): vimeo.com/26339130 The video is rather long, but it's content-rich. Quote Link to comment Share on other sites More sharing options...
Admin Rodney Posted May 6, 2015 Author Admin Share Posted May 6, 2015 Technology is catching up! What amazes me is that much of what is accomplished in that (last) video can currently be accomplished in A:M (albeit not with the smooth workflow that one would prefer due to reliance on plugins). While the underlying tech to get at the ultimate workflow would be to incorporate some of the latest and greatest subdiv tech... on the lower end an update of the following would bring about a near perfect match: Split Patch (plugin) - incorporating it more fully into the UI and/or allowing it to be assigned a shortcut key. I'm not sure what it would take to resolve the more difficult aspects of splitting patches nor of incorporating it into the UI. A rewrite of core code from scratch would likely be necessary which realistically rules that out as an option. A:M Loft (external program) - the video makes a lot of lofting and A:M has not taken advantage of lofting. I assume this is primarily because one has to define targets anyway so a modeler might as well just extrude repeatedly to get the surfaces where they want. Still, lofting does represent something that looks cool and does provide a useful approach to modeling. With regard to lofting... Sweeper - sweeper is a specific implementation of lofting (and alternately duplicating) and if updated with additional options or more fully integrated into modeling ui would offer the 80% solution (with regard to what is on view in the video). Sweeper was an initial look into what could be accomplished. Cap wizard (plugin) - This is one that might have fallen off most folks radar - it's basic usage proved a case for closure of simple surfaces. In a way this is similar also to the Font and AI wizards which perform similar function in closing off a surface using existing CPs Connect plugin - a simple concept proving how a series of splines can be automatically converted into patches based on their proximity to one another. I mention this above but having shortkeys for items not more fully integrated into the UI would make short work of automating tasks and smoothing workflow. Perhaps if the code for each of these plugins could be published then others would be willing to plus them up. Quote Link to comment Share on other sites More sharing options...

Just an observation. Quote Link to comment Share on other sites More sharing options...
nemyax Posted May 22, 2015 Share Posted May 22, 2015 It's actually the same paper. And now we can see its subject matter in action. Quote Link to comment Share on other sites More sharing options...
