Okay I went the long route and tried the demo for windoze with parallels.

And weeee it seems to work. I still get some strange triangles here and there and I'm not sure howto connect and edit the nurbs surfaces to make one giant nurbs surface that i can convert to mesh, but simply selecting it all using the preview function for the meshing and then exporting to obj after that does the trick!!!


Thanks alot, I will now have to learn rhino I guess

[polynurb]

cool that it worked for you...

iges when imported into rhino (&/or when exported), loses its solid data, hence you get all the single surfaces...

detailed description: http://en.wiki.mcneel.com/default.aspx/ ... rIges.html
and
http://www.rhino3d.com/tutorials/troubl ... ges-us.pdf

depending on the host application (and the person modelling with it), you should however have a layer for each object or identical objects/components.

so what i do is when i get an iges file is right click on layer>sel objects>"_join"

which makes a polysurface out of the single ones, which means that the mesh will be generated across the entire polysurface, matching triangles at edges. usually iges/nurbs files (if from mechanical applications) are very clean... you might even be able to selAll>join... but it is very inefficient selecting so many surfaces at once... it will be much faster doing it part by part ( don't join more than 500-700 surfaces at once)

btw. to control the rhino mesher accurately, check the description in help>helpTopics>contents>documentProperties>Mesh

reading this stuff it is a bit painful at first,... but it will improve the quality of your meshes once you mastered it...

enjoy,
p.

Cool, Ill check those out - Thanks a bunch, Poly!

Can't believe how good this is working now

...are you telling us this is rendered ..

[JorisMX]

Yes, this is one of the 10 gazilion CAD data objects im setting up for rendering

Oh, btw no SSS used here... and it really does show in renderspeed.
I got a benchmark around 1200 rendering this and other parts in 5000x5000 px size on my dual quad core.

Glad you like it.

Errr....cool.

Wow!

[bjorn.syse]

What a masterpiece!

[lllab]

polynurb, this is really incredible work!

can you tell some hints what material you used, what enviroment setup?
this looks 101% real:-)
cheers

thanks.. but JorisMX rendered that image....
... i just gave the hints about how to import those .iges files....

his material is amazing...absolutely on spot... without using sss...

[JorisMX]

Poly, I'm the one who should be ashamed : )

Thinking of your glass bottle renders etc. which totally blew me away last year. I was trying to get it to look like yor renders. But even w/ the material you sent me I never got it right , hehe.

Anyhow lllab, thanks alot.
I shared the material settings on the mxm subforum, but i'll just post them again:

These are the 3 Layers of the material:







You can easily play with the weighting to get different results.



About the Environment, I'm not 100% sure but afaicr this was a very simple Skydome set-up for all channels using 242-white (bowes to mike verta)
Once I've optimized the material and cleaned up the names I'll upload this to the mxmgallery. That is when it actually starts updating!

hello -
please excuse my ignorance up front, and it seems that responses in this thread are in this general direction. here is the problem:
i have a .dwg file of a chair that i need to use in a rhino model. the problem is that when i import the .dwg into rhino, i have no control over the mesh. when i render the model with maxwell, the mesh on the imported chair is not fine enough and it appears fairly voxelated (?) in the final. any ideas on how to solve this issue?

thanks,
jc

[polynurb]

without knowing what the geometry looks like it's hard to tell...

just two quickshots: if your geometry is mostly planes and edged/flat surfaces you can try to turn the whole chair back to nurbs with _meshtonurb and then _mergeallfaces(takes time/use on subparts); but it won't be good for round/organic models, or if the polycount is very high(takes forever)!!

then you could also extract parts of the mesh with _extractconnectedmeshfaces rebuilding them piece by piece.
extracting the controlpints of the mesh and duplicating its border often work very well for making patches out of them; but rebuild the curves before, to get rid of the polyline stuff...

[JorisMX]

Okay so here's a small update on the geometry front.

Initially this thread was about importing CAD data in order to render it out with maxwell.
After trying polytrans and later rhino for the imports I managed to get these models into cinema4d.
At this point I was still unhappy about the lack of tools for editing mesh structures and other parameters.

The thing bothering me more than anythign else was that I was stuck with a triangle populated mesh that didn't give me the flexibility with subdivision as I wanted.
In short I wanted a clean quad mesh.

A week ago I stumbled onto this link that jotero (thanks so much) posted in his gallery.
Today I tried this wonderfull (free!) software called graphite 2.0 running it in vmware on my home workstation utilizing this tutorial on generating quad-meshes with the PGP algorithm.

Here's a screenshot from their website



I know I must sound like I was working for the people programming it

But I'm very happy to see some software actually DO what I was looking for:
Spreading a nice smooth surface across a hires tri-polymesh which causes edges and seams in my maxwell renders.

I must add tough that I'm incredibly suprised I havn't found any of these functions in bigger apps like the autodesk empire range or other more known packages and modelling apps.

Once again thanks so much jotero, this is such a timesaver for me.

And since we all like the standford bunny so much...
