Complex Mesh Modeling (Warbird Head)
show user profile  Ygg
Hallo,
im going through some training meshes, i found this exellent warbird mesh from Mike Dilliott on trekmeshes, im a bit baffled at how you arrive at such perfect squares in such a complicated shape

i can work out the details but what is the technique to start with, is it lofted, boxmodeled, meshsmooth? so basically the typical Hwygamt (How would you go about making this)?

I only see one view there, from the Left camera angle? Anyway, from that viewpoint, the shape doesn't look all that complex to me. It's definitely turbosmoothed, which is what gives it the resolution, but if you want a better look at topology, then convert to edit poly and "quadrify all". This will remove all the mid-edges, and give you a cleaner view of the topology as quads.

That said, it appears to be a nice model, and you can probably get it just surface modeling a few primitives to start.

yeah but these squares are perfect to the screen, i dont really need to quadrify (although a cool tip that), you see the squares already, i doubt even turbosmooth can deliver that

Ok, I see it from the front now. It's hard to tell what the topology looks like. You need to quadrify all to get a better idea. The topology looks a bit messy to me, with a lot of smoothing artifacts too.

You get that kind of result from auto retopology. He may have just sculpted the object, then used automatic retopo to create the mesh, then either TS or meshsmooth. Wrapit creates a result like that.

yep, good eye there, discouragingly even a mesh this good seems to be troubled, there are a lot of artifacts and errors, the warbird is such a tricky shape, it baffles me how they managed to do it initially

ahh wrapit, well possible, cant judge it since i dont have it, mesh smooth and turbo smooth dont strike me as real retopology tools but more topology enhancers, this one looks more like retopo indeed, how could you model it while keeping these perfect squares all over

Those perfect squares, as you say, definitely indicate some sort of automatic topology. The reason I say to quadrify all, is because if you look closely, you'll see triangles in areas where they shouldn't be... at corners and curved edges. Removing the visible interior edges would reveal this. This is bad topology, and no one modeling this by hand would want to do that on purpose. That kind of thing is sure to cause pinching and artifacting.

It's a cool shape, but it could be had using edge extrusion modeling with sub-d. The topology wouldn't have all perfect little squares and tris like that, but would have a more logical topology, and smoother surface.

yeah and less artifacts, close up this mesh is not quite viable, ill give edge extruding and sub-d a try, but its a tough shape, its that vicious organic-technical mix, ive found a few warbird meshes but all improvised and flawed, thanks for the input :)

That mesh is faaaar from good. Sure, not that bad, but you're giving it undue praise.

It's a horrible mesh..I don't know why this would be something you'd strive for.
If you really want to have that square topology, you can do it to any model in Houdini with the divide sop.

That mesh is broken. It is not a "good" mesh.

You need to learn about 'proper' edge-flow.

How models will deform when animated.

Proper articulation of joints / muscle groups.

This is 'good' topology of a face - unwrapped. Notice how the edges loop around the eyes, nose and mouth. This allows for those vertices to move without distorting the overall shape of the face.






Similarly for the body, legs, arms... Certain edges around the knees, hips, shoulders etc are placed closer to allow for a greater range of movement.



Never heard of 'training-meshes' or 'trekmeshes'. But what I've shown you here is more along the lines of 'excellent meshes'...

Check out www.hippydrome.com for more examples and greater theory.

I looks like it was modelled in MOI or Rhino, and converted to fbx within one of those programs.

"I looks like it was modelled in MOI or Rhino, and converted to fbx within one of those programs."

Yep. Or Modo's MeshFushion. Meshfushion will convert to complex, small quads like this too, but with no attention to edge flow around corners, or curves. It tends to put tris at pointed corner edges (quads cut off at midpoint, just like in these screencaps) of a hard surface model. Either way, it was definitely an algorithmic quadrification of a mesh, not hand modeled.
