TurboSmooth and meshsmooth
show user profile  Rawashdeh_omar
Hi guys,
since I am fiddling with vray for the time being I am really concerned about memory usage by 3ds max, and what is the most efficient way to smooth your model.

I searched on Google the difference between the Meshsmooth, Turbosmooth, and smooth modifiers many times, from what i get... the difference is this:
smooth modifier : modify the normals so that the look will be smoothed (no increase in poly count)
mesh smooth : use NURMs (increase poly count but not as much as turbosmooth)
turbosmooth : increase polycount for your whole model and cant be applied to specific part of your model

what i don't get is how turbosmooth is better for memory if it increase polycount more than meshsmooth?

if anyone can clarify in simple words Id appreciate it very much, Iam not a 3d geek so i need it in simple words for newbies!!!
thanx for your time and help.

it's an algorithm.

So long as you have enough memory to store the resulting vertices / mesh data, you can 'subdivide' (ie: turbosmooth) your mesh. Each "iteration" of subdivision, divides each polygon into 4.

Ie: A 6 sided cube with 1 iteration will have 24 polygons. Iterate it again it will have 96 polygons etc.

I think Meshsmooth is an older modifier than Turbosmooth. Both are woefully inefficient compared to modern subdivision techniques (see zBrush / MudBox) - or rather, the way 3DS Max handles lots of polygons compared to these programs is inefficient. Different tools, different jobs.

MeshSmooth (with NURMS) and TurboSmooth give you the same polycount.
TurboSmooth's implementation is better: it's faster and uses less memory for its computation. Plus it has vertex and edge weighting which can allow you to get a good result with less iterations.

These algorithms are not meant for optimal output. If polycount is at a premium, you should add the extra geometry you need and edit your normals manually. Shorter render time vs. longer production time.
