What Video About
In this review, I explore the integration of xNURBS, a professional tool for surface modeling, into Plasticity and compare it with Plasticity's native patch and loft features. I share my initial experiences with xNURBS, highlighting its capabilities and limitations through a hands-on project. I also delve into its early adoption phase, discuss upcoming special offers, and examine the tool's potential impact on 3D modeling workflows. My goal is to understand whether xNURBS truly revolutionizes CAD modeling in Plasticity or if it's mainly hype, by comparing it to Plasticity's already impressive features.

Patch is limited by cut or broken lines that form a closed perimeter. I think xNurbs doesn't need a closed perimeter or broken curves... it detects the design intent based on where the guiding curves are. Patch requires a better definition of curves or may cause errors by being more strict in the limit information. xNurb is a little smarter

From my few little tests it does seem like a great addition but I think it’s an addition for the pro-level reflection peepers in the discord rather than poly modelers who are keen on trying something new. That said… it’s super easy to use and does look better in some cases!

Just as a minor technical note -- you cannot just extrude curves at the midline and use g2. A linear extrusion is not g2, it is g1, so you are giving XNurbs contradictory constraints.

@nikita.kapustin 4 ай бұрын

"you cannot just extrude curves at the midline and use g2" -> You mean this for the normal loft/patch, right? Because if I extrude the midline curve and use xnurbs on that same midcurve, I can select G2. (But not with patch) Or what do you mean exactly and how to solve it?

@nickkallen1 4 ай бұрын

@@nikita.kapustin When you do a linear extrusion it is not in fact g2. This is clearest at the bowl of the spoon, the extrusion continues in a tangential line off of a curve. So xnurbs can handle contradictory constraints but it will produce suboptimal results

Yeah it's a new tool implementation into Plasticity, so we just have to see how it unfolds and how we can implement it in our workflow. But I think xNurbs is not intended for casual/intermediate users. It can produce super high-quality results (like I will show in the upcoming video) in some examples, but for literally 97% of the people the standart Parasolid/plasticity functions are beyond amazing

Thanks for posting this informative video. I don't think the guys developing Plasticity are doing themselves any favors by restricting the feature set in the Indie release as I think it would be fair to say that most Indie users, like myself, are hobbyists or beginners who can't afford the additional cost. If you take the Autodesk 3ds max Indie release, you get everything for modeling, rendering and animation at no extra cost as the product is aimed at users earning less than $100k a year. I doubt there are many Plasticity users earning that much.

The addition of XNurbs has not made plasticity more expensive afaik. Nick explained that XNurbs is not a fix for bad geometry and that it is still better to work with 4-sided edge boundaries. The matcaps look better if set XNurbs flatness to 1. For Rhino XNurbs is a productivity tool, creating nice blends in Rhino is a lot of work and takes a lot of time and experience. Plasticity blends are much easier to use than Rhino, but XNurbs is still a wonderful addition and hopefully will pave the way toward easy-to-use surface analysis and UI feedback.

I remember a time (around 15 years ago) when in automotive design single span patches were the way to go. It went even so far, that Alias modellers were getting problems if they had 2-3 spans in their surfaces. If I look at the interior isoparameters of those X-NURBS surfaces... I get cold shivers... 🥶 Definitely not single span😂 BTW: If the adjacent surfaces are messy, you will get messy patches with tortured highlights. No X-NURBS trickery will solve that.

@LynxErgo 2 ай бұрын

So what xNurb has as advantage compared to patch?

@SteveThinman 2 ай бұрын

@@LynxErgo It gives you an automatic solution and more importantly it can have more than 4 sides. A patch can only have 4 sides and you have to decide what is the best way to make your "quilt" out of those four sided patches. (Of course, you can trim a patch to have more than 4 sides, but it's even harder to align other patches on trim boundaries.) As long as you only care about the look of your model, xNurbs will give you a quick solution. As soon as you start offsetting the A surfaces (in other CAD software) to create B surfaces (thickness) then the increased amount of interior isoparameters MIGHT cause problems, especially if they have multi knots. I have not tested it, therefore the MIGHT. Generally, the less spans a surface has, the cleaner it is mathematically so, it is more suited to create offsets of it.

@SteveThinman 2 ай бұрын

@@LynxErgo NURBS modelling is very different from polygonal modelling (I'm doing it for over 30 years now) as you always have to think in four sided patches and you have to take care of the continuity between those patches. Continuity is never a problem in polygons as they are always G0 (positional) only and only the smoothing algorithm determines the appearance. xNurbs might help you solve complicated surfaces but if you really want to learn NURBS based modelling, try the hard way and try to solve with patches only.

It was my impression if you were day one you get all updates up to 2.0. Since we are at 1.4 seeing features slated for 2.0/studio only does feel kinda lame. I understand that actually paying for things makes them better. At this point its not clear if we can upgrade from indie with even a discount though. If the gap between indie and studio gets wider by the time we get to 2.0 then in my opinion it was a shitty deal to ever go with indie and it feels a little backhanded when you supported them on day 1.

You're completely ignoring topology/export/quads. For my purposes, Xnurbs IS the magic pill for clean topology going into the game engine. We need to optimize the mesh later by deleting extra edge loops, and it's impossible to do that if it's just messy tris and/or Ngons.

In the beginning, on the "bottom" with xNURBS you're using G2 alignment to an *extruded surface with no curvature* and are thus forcing it to match curvature to something *without* curvature. But on the Plasticity patch you're using G1 alignment which only needs to maintain tangential continuity, so a) it doesn't appear to be apples-to-apples comparison, and b) the G2 alignment - aka the "curvature continuity" - is probably causing the resulting surface to pinch where CV's are trying to match a non-existent curvature. On the "top", you do the same thing in using G2 *curvature* continuity for the xNURBS surface, but then trying/failing to use G2 with Plasticity patch and then just accepting the G1, which I'd offer is the better alignment constraint for both. Obvious question is: Why didn't you show xNURBS with a G1 alignment to the extrudes and compare apples-to-apples instead of using G2? FWIW. even when I model in Alias, I don't use G2 continuity on the edge of a surface which doesn't curve.

Thanks for that in-depth explanation, wasn't aware about that the extruded face can only be G1. Learned now:)

@@nikita.kapustin - Glad that helped. That all said, you're correct in saying that for these kinds of surfaces xNURBS probably doesn't make much difference. Even less difference for videogame assets (although that could change as game asset quality quickly goes realistic). Where I suspect xNURBS will make the biggest difference is in the kinds of multiple-surface-blending-together-at-the-same time situations that sometimes pop up; things like motorcycle forks. Those blends can be tricky and require a fair amount of work to get nice surface quality. And again, this is probably of greater importance to the professionals like myself that want to export geometry to SolidWorks or Creo and continue work in those applications. For game assets, once it's in Blender or Modo or whatever, the clean-up can be moving some vertices, so the surface quality doesn't have to be as clean. Is it worth the extra cost of a Studio license? Honestly, I sometimes still can't believe these tools are running on $1k laptops and cost a few hundred dollars. When I first started out, less capable software was tens of thousands and ran on SGI workstations (or similar) with a UNIX-based OS that would cost another $10+ dollars. If someone is serious about designing in 3D, I consider it a no-brainer; especially given that this is a *perpetual* license. If someone is a hobbyist, then take advantage of what's freely available, which is still quite a lot.
