keyframe posted:Sim it. Yeah, start with a wavy noodle, put some constraints on whatever it hangs on and let it drop flat them side/animate the constraints closer together to get the curtain look. basically you are taking a sheet, sim it so it drops then bunch the mounting points together to create the look. Save out the model and viola. If it has to animate in a shot you can do all the sim prep in preroll or have the sim start at a precached point.

One last example of scanning from the Getty Villa. Probably overkill on the polycount and texture resolution, considering the scan only consisted of 12 pics.  Recently, I saw a demo of Autodesk Fusion. I was pretty impressed and it looks like a fairly legit competitor to packages like Rhino. However, it is cloud based as far as I know and I refuse to use cloud based products (even though I realize that is where most of this stuff is going). Does anyone here have any strong feelings about Fusion one way or the other? I feel like if I am going to learn a NURBS based (engineering package) Rhino is best but Fusion did look pretty impressive from the demo. ... and yes, I know Adobe has gone cloud and Recap 360 is cloud based yadda yadda ... I just don't trust it.

Rhino is fun. I've been messing around with the OS X version (free while it's in beta, which knowing McNeel's development schedule will still be a while yet) and have become pretty decent at NURBS modeling in the process. Rhino is probably the friendliest CAD package for someone coming from a general 3D background, where something like SolidWorks is very much oriented toward a more engineering-based mindset.

 This is a scan I took(well, my wife took of me) with the Structure Sensor using the iPad app "itseez3d", I'm so loving stupid though I can't load the .MTL (zbrush can't do it, and maya doesn't recognize it, and I'm not smart enough)... it's a photographic MTL, so it looks just like me when the texture on. But that screenshots shows what the actual mesh is like. Whenever I get un-lazy I'll take some 360 degree photos and try to compare Agisoft's (probably a million times better) to this laser sensor. I've yet to get "Skanect" to connect via wifi, so maybe using my PC's computing power can get more resolution, I'm not sure and I haven't read the loving manual at all.

Hell, icem surf doesn't exist just for shits and giggles. I design cars for a living and everywhere I've been uses alias and icem. We spend months getting highlights perfect. Which always seemed kinda weird to me when tooling tolerances can't get near. Look at highlight rolls on door shuts etc for example.

Here's something I did a while ago: Based on a model from WoW. Mostly trying out some volume rendering plugins for the real-time smoke and fire, which gets incredibly expensive quickly as it's CPU-bound. Apparently NVIDIA has a really good and fast GPU solution, hope the engines get to implement it. Elentor fucked around with this message at 22:04 on Feb 10, 2015 |

We used to make fun of Dreamworks in school because they were locked into a NURBS-based pipeline and were making feature films in NURBS. I'll stop poking fun at it... as much... Disclaimer: This isn't exactly my area, but I'm a software engineer at Autodesk working on rendering CAD-y things -- I work on the path tracer that's in Fusion 360, for one -- so hopefully I have some vague notion of why the modeling works the way it works. Far as I know there are a couple of reasons NURBS and other spline types are the thing in this domain. Some of these reasons are mostly historical, some not. - CAD modeling is mostly constraint-based, where someone specifies that this or that curve or surface should be within this bound, or tangential to this circle or whatever. Figuring out how to fit the final model to a very large set of such constraints is doable with a parametric model, but almost impossible with a polygonal mesh. - Relatedly, splines are very predictable and controlled. You can specify points that the surface or curve will always pass through, and the other elements define some sort of nice hull that your curve will definitely stay inside which makes it easy to obey mechanical constraints and ensure that all your various bits will fit together and can handle whatever forces the simulator says they can. - In contrast, doing mesh subdivision moves your vertices around. You can actually get a perfectly smooth surface this way: the result of doing Catmull-Clark subdivision infinitely many times is well defined and you can evaluate that if you really want so it's not that a smoothed mesh is insufficiently smooth. The problem is that the result of doing that might to not look that much like the original mesh if it was roughly tessellated to start, and it definitely doesn't play nice with mechanical constraints. - The amount of data required to accurately describe a surface with splines is very tiny, even compared to a reasonably tessellated mesh. Less important now, although still practical, but 10-20 years ago working on a complex mesh at manufacturing detail was too expensive to consider as I understand. I guess the thing to remember is that most CAD programs started out as (and still are) mainly 2D-affairs intended to let engineers sketch the parts of a larger design in much the same way they sketched blueprints. Surface modeling of the sort that Alias and Fusion do is a newfangled and frightening concept to a bunch of people and still needs to interact nicely with the technical drawings. I should also probably mention that Fusion uses T-splines rather than NURBS. The Fusion people tell me that NURBS are now old hat and everyone (here at the evil empire where we have the patent, presumably) should totally use their fancy T-splines everywhere. I just write the code that draws the pictures so it's all triangles to me, though.

So long as you don't try and pretend you'll do any serious rendering on it you're fine. Save money on that part and just keep it for grunt work. You don't need a ridiculous laptop for it - you could get a mid range one to model on and an i7 desktop for less than a workstation laptop. Get them set up with distributed rendering and you've got the best of both for less.

^^^ I use an i7 laptop with a decent Nvidia GPU and get most of my 3d done on it just fine. Unless you are doing huge scenes, it should be fine for modeling most assets. As long as you have a decent i7, Nvidia GPU and of course, lots of RAM! This is pretty cool info but doesn't exactly address whether or not I should opt for Fusion or Rhino to learn. Fusion "seems" to have more advanced tech like T-splines but I am not familiar enough with either package to make an informed decision as to which one might be better. Is Fusion meant to work in conjunction with Alias (sketch?) then? Draw the blueprints in Alias and then knock out the model in Fusion? Still very turned off by the fact that I am forced to use "the cloud" when using Fusion. WTF Autodesk? If this is where all of your products are going, I am jumping ship. Basically - I have made friends with some toy designers and craftsmen and they all use Rhino or want to use Rhino. I tried to convince them to use Zbrush but because of the need for real world measurements and engineering type tools, they are pretty biased. I will say they let me use Zbrush to prototype a Frozen toy for Disney. Interesting getting a base mesh from a Rhino file (STL) and then modifying it in zbrush for final prototyping. Rhino is not good with organic shapes (like cloth) but it is VERY good for knocking out quick models from blueprints etc. It is used extensively in toy design and manufacturing apparently. Was trying to shoe horn Zbrush in their workflow but I was competing against a Rhino guy, so it got kind of weird when I was trying to convince them why Zbrush might be better. Bottom line is that realworld output often requires engineering software. CAD software like AutoCAD and Solidworks used to be the standard but I think more and more people are inching towards Rhino or Fusion . . . especially smaller shops. sigma 6 fucked around with this message at 13:00 on Feb 11, 2015 |

Ohh - I see now. I was confused because Autodesk bought Alias / Wavefront a while back and here I thought Alias was the drawing program. It is actually a modeling tool, not a drawing tool. So then . . . how many NURBS packages does Alias ... ahem... Autodesk need? Doesn't Fusion do what Alias does then? Seems like their functionality would overlap a lot for industrial design. The company I contracted for on the Frozen toy project was VERY small. They had one guy they had been working with for 10 years or more who was a Rhino guy, so they were naturally biased towards it. If I really wanted to, I could model NURBS in maya but it is kind of a pain IMO. The boolean operations in Rhino (and I assume Fusion etc.) work much better. Regardless, the stuff about car manufacturing is fascinating. RizieN: Thank you for that link! Zack Petroc is some sort of zbrush god. A nice guy too! Since I believe the toy has already been released, I will go ahead and post a render of the toy set.

I'm trying to adjust the wood grain texture from a procedural but it's very time consuming to have to clone original>sub object select element>move>align with original>delete original for every object I want to adjust. Here's a helpful gif to illustrate:  Is there an easier way to do this? I hoped xform was something like this, but it isn't afaik. edit: 3ds max also

The cheap metal has perhaps a bit too much frequency in the noise tab and is missing a bit of resolution if you want to output it at that size.

drat straight. NURBS in Maya sucks. I am always amazed when people (mostly older modelers) can model decent characters with NURBS patches. Original Spiderman was all NURBS I believe. Also the T-Rex in Jurassic Park etc. etc. Was hoping Rhino and / or Fusion would have much better tools and judging by the Fusion demo I saw, they definitely do. The fillets in Fusion are pretty awesome, and somewhat interactive. Really, I am just looking for the FASTEST way to model hard surface objects from blue prints and yes, they will probably be brought into zbrush later and converted to poly. TIA! Regarding the grenade: Not sure why you can't use a normal map (or displacement) for the noise on the grenade. Remember that less can be more with these things. Too much bump typically looks pretty bad. Right now it looks like you have too much bump on the bottom part and not enough on the top. The contrast looks a little weird. Unless it is a mirror, glass, or polished metal, EVERYTHING should have bump. Even if it is very, very slight. Consider tiny scratches, dents, pock marks etc. Above all, look at your reference! Notice there is some VERY slight bump here with the aluminum(?) at the top.

The first Batman movie the batmobile was modelled in NURBS. I know this because I had to take a NURBS modeling class in school with an instructor that made it, and it was loving awful. Seriously, poly modeling is absurdly faster than NURBS modeling for me, especially Maya. I had to make a toaster and a motorcycle in NURBS and it was a grueling process full of broken tools and techniques. I'm sure there are programs out there that do it faster than Maya, but honestly subdivision surfaces are easy enough to master and what can't be done with that easily can be booleaned and cleaned up.

Today I have mostly been making voxel ships. It's not high enough res, I want it double or even quadruple so it almost just looks like a pixelated ship instead of voxelized ship. I think I need to get the program makers to implement a smaller grid size for this though, or cut my model up and re-weld in max. Also texture is just slapped on to make the program not crash.  edit: fixed it

I just learned me 4 point tracking in Blender yesterday, for this thread: http://forums.somethingawful.com/showthread.php?threadid=3700850 My result is this:  Which is, eh, good enough for a funny gif thread. I just followed the procedure that was in "every" tutorial: track the corners in the video, convert the tracks to empties, hook the 4 corners of a plane to the empties, texture the plane. Anyway, I had a couple of problems with animating the corners. In the latter half of the thing, one of the corners of the paper is outside the frame:  I just eyeballed the first, last and some keyframe in the middle somewhere. But I was wondering if it is possible to just set the position of the empty in the first frame and then add a modifier or something that moves the corner in the same direction as one of the other points. Or maybe something that moves it by the average movement of the three other empties? I thought that it could be good enough for that kind of video where there is just a little bit of camera movement. Followup question: The top of the paper deforms at one point in the video. I thought that maybe an edit could blend in better if it followed the deformation. So I could subdivide the plane and maybe add new empties in the middle points and hook the vertices there to the empties. But I don't want to animate all the middle points, so is it possible to have all the uninteresting middle points take the average position of the corner points? Does this even make sense or have I just found a hammer and everything looks like a nail now?
