I was peeking at the WoW models when I realized that, literally, all of them, are made out of triangles. I haven't even spotted a single quadrilateral, not at single one, only triangles.Is there any specific reason for this? I thought quadrilateral were master race and triangles should be avoided at all cost.pic related, its an harpy
>>520213preety simple, try to subdivide that model.Tris and quads are both correct, but for diferent purposes
>>520213> being this fucking retardedDid you ever export anything ever into any fileformat op?You're a fucking idiot.
>>520217it deforms like hell when I subdivide it
>>520213quad = 2 tristriangles are not bad or to be avoided if you know how your geometry will flow.
>>520218Not really. Care to explain? I recently started learning about this.
>>520213They get baked down into triangles. If you had access to the source model, you'd see quads instead of triangles.Technically speaking, every modern 3d model is made up of triangles. The quads are just a useful abstraction.
>>520219yup, tris are bad for subdividing, deformations etcbut in low poly modelig like your example controlling the way the tris are distributed its necessary
>>520222I see, thanks for the explanation. I'm guessing the only reason to bake them down into triangles is to reduce the number or vertices right? Or is there another benefit?
>>520222sometimes, but in low poly modeling sometimes you need to model in tris because a quad its not allways a flat surface
>>520225Can you mix tris and quads when modeling?
>>520226Yes. But you need to be mindful of the effect it will have on various properties and future alterations. Apparent smoothness and subdivisions/tessellations will be affected.
>>520221Look op:Quads don't exist. The only polygons in existance are tris. Atleast in the graphics card.Every model ever will at some point be out of tris and tris only. The "only quads" thing only exists, because tris are shit to work with from an artist standpoint.That still means 1 quad = 2 tris.1 polygon = x amount of tris. Doesn't matter if it's a quad, or n-gon.Everything is tris.Every. model. is. tris.Thats why when you import models from a game, you get what? tris.Because quads don't exist technically speaking.You got it now? I wrote it down 5 times for you, I hope thats enough.
>>520218Obviously OP is a newbie. You weren't born with all the knowledge in the world neither, am I right?What a bitter person you must be
>>520224> I'm guessing the only reason to bake them down into triangles is to reduce the number or vertices right? Or is there another benefit?Triangles are guaranteed to be valid. Given 3 points in space, they will be a triangle no matter what. Also, rendering pipelines have been optimized heavily for triangles for this reason. The number of (indexed) vertices in the model will be unchanged regardless of whether you represent the polygons as triangles or not.
>>520226yes you can buy you need to be careful if you subdivide the mesh both are the same cube but the second one its triangulated
>>520213Those are the legacy models.The updated models are quadrangles.
>>520233Thats still triangles broo, I'd know I do machinima with them lol. Their shit to work with, if I knew what I was doing I'd do a complete re-topo of the original wow model.
jesus how retard can you be.
>>520235Everything is triangles when it comes time to render.
>>520221I do.3 point can define exactly one plane.With 4 and more points it could be much more ambiguous if only just one piont isn't in the same plane as the others.See pic related how can a render engine translate a quadrant if their point aren't in the same plane.
>>520275It isn't and it can make pretty strange resolutions.
>>520235That's a triangulated quad model Every quad model gets triangulated eventuallyIn this case, probably during export for game use, which you (or whatever source you got it from) obviously ripped subsequently after the triangulation
Quads make artists lives easier because they can be subdivided without disrupting edge flow. Edge flow makes rigging/animating easier because it makes things deform more evenly and predictably.The thing is, Quads don't exist.The software you're modelling in is showing you quads, but everything is still tris. Tris are the only thing the there is in polygon models. The software is showing you quads because that's the best thing for you to model in for the the aforementioned reason.If you tell the software to triangulate your whole model, nothing actually changes. It just forgets where the essentially imaginary quads are a and shows you the triangles that make them.On top of this, the original WoW models are low poly to the point that the modellers couldn't have created such detail with using tris.There's nothing at all bad about using tris in this context.The only reasons you should avoid tris are because if you want to subdivide your mesh later it will be a mess, and if you want to animate the model it will be more work for you cleaning up your weight painting if the edge flow is fucked.
>>520218This is why this board is dead
>>520726He's right tho, OP is an idiot, anyone who have spent atleast a day studying 3D would know why the model is as suchWe've all been there, difference might be that we weren't this stupid when we posted on 4chanI for one, welcome the already present hostility on /3/, the very same on literally 90% of the boards; if you can't handle it, then get out of the kitchen, it's literally that simpleThis very same hostility was what forged me to be the artist I am today; and thanks to being told time and time again I was shit, it gave me drive to not be shitPerhaps I am one of those individuals who respond to "harsh" (honestly not all that harsh even) motivation, but seriously, if you can't handle it or if you think that these type of posts are exclusive to /3/ then you must've just arrived here or came fresh from /b/
>>520739>not knowing something makes you an idiotLiteral autism. Being a noob != being an idiot. He'd only be an idiot if he learned nothing about tris and quads from reading this thread (and hopefully doing some googling).
>>520797Using the term autism in this case doesn't make a single shred of sense, not even in the way 4chan uses it wrongly. Confirmed for /b/tardSeriously? Semantics are the only thing going for your end of the argument?He is an idiot, I don't give a shit if it's due to ignorance or incredulity, he is an idiot in /3/'s eyes because this is no different from someone making a thread when they haven't read the fucking sticky. It's clear he's not only new to 3D, but /3/ as well because he's one of the many idiots who thinks one question like this warrants a whole threadHe got like 8 answers saying the same thing and now the thread is dead aside from just us arguing about him being an idiotConclusion? Post in the fucking question thread instead of making another fucking thread, and save this cancerous useless threads when there is already one up
Why aren't we able to model in quints yet? Is it due to the law of diminishing returns or are the jews involved?
>>520277this should be higher up!
>>520233I would fuck that gnome
>>520224They are not 'baked' down to triangles. As people say a quad is two triangles.One edge is made invisible so you, the human editor, have a better understanding of what you're working with since a quaded surface (surface of paired triagles) smooths and subivides better.The computer doesn't care it just renders the triangles so it do not need any extra data about what edge is 'hidden'. So final export formats will save your mesh without this 'isoline' display information for efficiency. So you just see the triangulated mesh upon ripping the files.If you had access to the working file the artist responsible for the work used you would see a more conventional quaded geometry.However, 'micro poly' meshes for games like the one in your OP picture will use a lot of odd triangles and unconventional geometry since they're so performance oriented.
>>522208Everyone would fuck a gnome. They're like kids that are legal to fuck.
>>522210It's not exactly like that. 3d modelling packages work with polys with more than 3 edges, but they output everything in tris to the gpu.
>>522222amazing get.Gnomes get.
>>522243Like you wouldn't fuck a gnome in the ass.
Game engines triangulate the model by default. Modeling/Sculpting packages display quads or trisSome engines are being able to display quads now but that just a cosmetic thingIts nothing special or serious That's just how its been.Marmoset Toolbag is built like a game engine but for pure rendering. It now displays quads. Last version only had Tris.
I forgot to say All models are actually triangulated. A polygon has 3 sidesA Quad is 2 polygons sharing an edge.An Ngon is a polygon with more than 5 points and no edges connecting them. Engines automatically triangulate Quas and Ngons because that's how it reads them. When Doing hardsurface modeling its best to stay with Quads and occasional Ngons if the face is completely planar
>>522301>Some engines are being able to display quads.Nope, maybe they can handle quads, but no display them, the draw type flag in both opengl and directx for passing quads is deprecated and I don't think works.>A polygon has 3 sides.Wrong, it has 3 or more sides/edges. A quad is still a polygon and it exists in real life geometry as well as geometry, it even exists in computer graphics.>A Quad is 2 polygons sharing an edge.Wrong, a quad is a polygon with 4sides/edges.>An Ngon is a polygon with more than 5 points and no edges connecting them.Wrong, an ngon is a term used in 3dcg mainly, which stands for a polygon with more than 4 sides, so a polygon with 5 sides, also known as a pentagon is an ngon, so is a hexagon and so on.>Engines automatically triangulate Quas and Ngons because that's how it reads them.Correct(although not all engines do it, most need the model triangulated, in order to read it properly).>When Doing hardsurface modeling its best to stay with Quads and occasional Ngons if the face is completely planarDebatable, usually whatever modelling you're doing, the best option is to stay in quads, except if its faux poly, which favors flat shaded triangles, pic related.Please don't post false information anymore, it's confusing to the newbs.If you're interested in understanding 3d graphics, read up on opengl, direct x, or topology.
>>522393Wow model Viewer. Rip all the models you want out of WOW.
>>520802>Post in the fucking question thread instead of making another fucking threadLel.Because this board is so flooded with posts thread management is important, huh?3d is a huge topic and obivously not everyone is on the same level, let people ask away instead of being a bitter forum-dwelling faggot..
>>520213Game engine love triangles over quads. What I was taught and usually do is model in quads then convert to triangles before I export to engine.
