Rally need help with Corridor Surface Triangulation

[Anonymous]

Hello, I have strange problem with corridor surface triangulation. Maybe I do something wrong for corridor from the start? As can be seen in pics that I attached, there's some surface degradation that I can not understand. At first look everything seems ok, but when I go to Realistic Visual Style something happens :)... End when I try to render this, I get more uglyer result than this shown...

anybody
?

It appears you have a jitter setting in your visual styles that causes your REALISTIC style to look - well, jittery.

I've experimented with VSEDGEJITTER, but it doesn't changed appearance of my triangle faces...;/

I don't have the drawing at the office to search out the difference in Edge Settings - but it was impossible to view your triangulation with your edge settings because of the Jitter in all of your 3d viewstyles.

I am attaching the Realistic Visual Styles settings that I think are the out of the box settings. These and the conceptual help me visuallize the surface if I need to troubleshoot something.

Here's another link to the file of my intersection.

Here are a few things that will help you.

You have some odd triangulation in the center of your intersection which I fixed quickly by adding the "links as breaklines" and adding a few of the corridor feature lines as breaklines.

More to come.

From a modeling perspective, those triangles around your curb lines look really good- there aren't any blow triangles in the TIN. That is good news.

It must be an issue with the visual style. Let me try that.

[dana.probert]

When I look at the TIN alone, it's fine. The color differences are due to light/shadow.

I will look at the corridor object itself next.

[dana.probert]

I've looked at it from every direction, and your triangulation around the curbs etc (which is where you are pointing in the first two imags you posted) is 100% perfect. I've atteched another image where you can see the color differences, but like I said before, i think it's just a light/shadow thing.

The main rule for anything in Civil 3D is that if it looks good- if it looks like curb, if you quick profile it and it looks right- that it is right. Unless you have to render it (do you?) I think you are 100% good here.



This is an amazing corridor model, by the way.

[dana.probert]

sorry for the 100 posts in a row,

I did run the -render and got the same results. I think its a setting issue that could be fixed with some lighting, etc. It is not a reflection that the model is bad.

Ok, thank you very much, everything is clearer now and I'm 30 times happier, cause at least my model is correct. I know that some tricks could save me in rendering, but still it would be better if everything would look nice and smooth, cause from this model I will try to get animation in 3dsmax and if I export the model there, it gets also a bit dirty (in places of color difference). My client will need the best I can give him and its a bit nervous bagatelle that doesn't let me sleep well :)... I also thought of some setting tick that could do the job right, but I've tried so many variations in different places that I don't even know where I could do more changes (it's my lack of deep knowledge to this product). So I will ask you if it's possible to let me hear if something will come out for you. I believe that for specialist it could be the few minutes business, but for me it's taking a lot longer ;))...

[dana.probert]

have you tried rendering with a code set?

[Anonymous]

hmm, what code set?

[Anonymous]

ok, code set doesn't made any difference. I don't understand, it's just me who gets such a results in corridor surfaces or what? I've tried to do corridors in father's PC and there was the same result, I tried to do corridors in C3D 2008/2009 and I've got the same results, bad triangulation and impossible rendering. What's wrong with C3D? I am giving you my file again, maybe some day I will see it rendered correctly...

[dana.probert]

the code set renders the corridor itself, not the corridor surface.

in complete honesty, code set or not, rendering a road scene in the autocad environment is an exercise in insanity. There are other options. I just saw a thread on it in the past few days where people were posting sample renderings done in RDV and other packages.

Yes, I turned off triangulation in my surface style, turned on Code Set named "All" or something like that and faces were damaged the same way. I would like to render my model in other applications, but as I said if I export these surfaces to 3dmax or other applications, triangulation is damaged and incorrect (but Civil doesn't show that, it shows just the color differences). I see there's no one else who gets the same problem and I don't understand why.
