Hi Iwan, I am glad you are enjoying MoI - thanks for the feedback and posting the model.

Nice model - very clean construction!

> - extract U/V iso curve from any already built surface

This is something I expect to add to version 2, I think it will go as an additional command under Construct / Curve, where Project and Isect are currently at.


> - edit the surface with points on the drawing curves

You mean by editing points along the edges of a solid? Unfortunately this one is quite difficult to achieve, the structure of MoI's objects makes it hard to pull pieces of a joined solid around while guaranteeing that the edges don't pull apart to create gaps.

It's a lot different structure than a polygon modeler... This post here tries to explain some of the difficulties with squishing things with shared edges with this kind of object structure: http://moi3d.com/forum/index.php?webtag=MOI&msg=759.12

However, the same structure that makes it difficult to pull points of a solid around is also the reason why boolean operations work so well, since booleans create "trim curves" that mark regions of a surface that are inactive instead of actually cutting things up into tons of tiny slivery pieces like polygon-based booleans do.

ok thanks for the reply MIchael :)

Hi Iwan, I missed this part of your message:

Hmmm, can you post a small example .3dm file of something that is causing you problems?

If you have separate surfaces in your model, make sure to join them together so they are one connected object before you export to a mesh.

When you have joined pieces, MoI does extra work to make sure the created meshes have a common vertex structure along the shared edges. If you have just individual surfaces, that extra work won't be done and each object gets meshed slightly differently which can result in cracks.

Possibly PowerNurbs is doing an automatic join step for you or something...

If you have things joined together and you are still getting cracks, then that would be a bug, please send me any examples you have of this so I can fix them up.

Also, which file format are you using? If you are using OBJ format, it is possible that 3dsmax is not doing a good job of processing n-gons (more than 4 sided polygons). If that is the case you may be able to get a better result by switching the Output: option to "Quads & Triangles". It is not too unusual for programs to have difficulty in processing complex polygons with a lot of sides, I'm pretty sure that PowerNurbs does not export n-gons so that may be another difference that explains what you are seeing.

OK I'll check all those great advices and will keep you updated about the results !
thanks again

here is a render of it with Fryrender :

added to the Special thread Gallery :)

Hi Iwan, could you have a plugin for moi?

Iwan,

What steps did you take to render in Fryrender?

I downloaded the Fryrender demo and it does not import geometry.

Ed

Fryrender do not import geometry by itself, it's a render manager application only, you have to import the model in your favorite application (if a plugin available of course) and then you export from here.

hi Ed you could use Maxwellrender for that plugins available +plus studio that you could import geometry compose scene and render.....I choose maxwell just because of studio, Fry is cool 2

Thanks - I see that now. You professionals have more money to spend than me on render software :)

Ed

trust me it will pay off
