Swordsmanb 0 Posted February 8, 2005 Well, I already did quite some addons, but never had such problems with the "Component Convex Hull" operation... So, here's what's wrong: I completely modelled the Resolution-LODs of my latest addon and then copied the single parts to the Geo- and Fire-Geo-LODs. After simplifying these single components there were just some boxes of different sizes left (I should mention that the model is a building). Then I executed the "Find Components" and "Component Convex Hull" operations, and then checked the model for non-closed faces... and there were MANY of them, but I have no idea why!!! As I said, the components are simple boxes (and some cylinders). This is what I did: -copied the components from the resolution-LOD -pasted in geo- and fire-geo-LOD -deleted faces -removed unnecessary vertexes ("holes" for windows/doors) -created faces consisting of 4 vertexes each I also entered the coordinates of the vertexes manually to make sure that they all lie on one plain , but again I got the same non-closed faces. Does anybody know why this happens and what I can do? I'm totally helpless... Share this post Link to post Share on other sites
Footmunch 0 Posted February 8, 2005 A component is a 3d 'box' (it can be a cylinder, cuboid, etc), made up of _joined_ faces. Just because two vertices are at the same location does not mean they are joined. Try 'Merge Near', then 'C.C.H.' again. Share this post Link to post Share on other sites
Swordsmanb 0 Posted February 8, 2005 No, I think you got me wrong. I know that a component must consist of "joined faces". I didn't want to bring 2 different points to the same "location" (coordinate), but to bring one side of the cube (i. e. 4 vertices) to one plain, that means they must have ONE coordinate in common, for example z = 20. And btw, the components were originally made by using the create->... option, so they MUST be joined. So, my original problem remains, that I get the non-closed faces after 'C.C.H.'-ing.

Footmunch 0 Posted February 9, 2005 SSB - I'm just checking, but let's say we've got one wall, with one window. Then looking from the front you've got: +--------------------------------+ | | +--------------------------------+ +-----+ +------------+ | | | | | | | | +-----+ +------------+ +--------------------------------+ | | +--------------------------------+ (Pheer my l33t ascii skillz ) So that's four boxes (each with 8 verts, 6 faces) - CCH will find 4 components in this case, agreed? Sometimes the convex hull algorithm _does_ get it wrong, but that's usually only on 'complex' shapes - not standard boxes and cylinders... Share this post Link to post Share on other sites
Swordsmanb 0 Posted February 9, 2005 But I even don't have these windows, because these structures aren't enterable. The windows and doors are just "fakes", which I removed in the geo_LOD. I really just have big boxes (e. g. with dimensions of 25 x 14.2 x 17 m, but also some smaller ones). Is it possible that the whole model is too big? I know that theres a maximum of 64 x 64 m in x- and z-direction, and my model is within these limits, but is there also a limitation in y-direction? And does it matter if the model is on level 0 (in y-direction) or if it's moved ca. 30 m up? Share this post Link to post Share on other sites
csj 0 Posted February 9, 2005 I dont think the size is problem. I would select all in geo lod and delete. create your shapes from there run find components as you did before. Share this post Link to post Share on other sites
Swordsmanb 0 Posted February 10, 2005 Doesn't work either, I've tried this already... Well, seems there's no other possibility left than making the whole thing a bit smaller, I'll try this out and post here whether it worked or not. But thanks for your help.

Guest Posted February 11, 2005 I found that Component Convex Hull often created more problems than it solved. Best way IMO is to Binarize the addon manually (not using BinarizeIT) then scan the cmd prompt for errors. This way you can track it down to the exact component with O2 "fixing" things for you.

Swordsmanb 0 Posted February 13, 2005 Well, until now I never had any big problems with CCH, it always worked fine. And I found out, that when I made the model smaller, it also worked without problems. There were still some open faces, but less than before and I could fix that by inserting the coordinates manually. So it seems the size has an effect on CCH, but I dln't know in which way exactly... I finally solved this problem by making several models for the addon which I can put together in WrpTool. This has another advantage: Now I can make more details which was impossible before because the whole model was at the max. size limit. Share this post Link to post Share on other sites
