I can't find that option in my 1.2 build from last week. there's the BPA, a poisson reconstruction which are available in 1.1 and MLS (which I don't fully understand right now, I still have to read the corresponding paper) stuff in 1.2. the filter option "build surface from point" is not available in my build (2008-11-06). > third: my points-cloud is in the format > x,y,z,I > where I is the value of reflectance recorded by the LIDAR.

I have to deal with xyzrgb data (which in fact is xyzI, as yours) but as I'm not interested I converted that to an obj file by addingt a 'v ' in the beginning of every line. where dumb shell script for that is available upon request. I'm not quite familiar with the obj format, but I guess you could encode the color into that with a more elaborate shell script easily (depending in your scripting knowledge). cheers, norbert |

Hello everybody... i have some question about MeshLab: first: iv just compiled MeshLab on my gentoo. BUT: make install appear not do what i suppose: make install command scrolls down the folders looking for something to do but always say "nothing to do in...". I think im doing something wrong... couse after that meshlab appear not to be in my path! and not to be anywhere else! So im running meshlab from the folder where iv compiled it... second: i would like to work with LIDAR obtained point-cloud. I have loaded one of these clouds in meshlab and it appear working very well (I have converted the cloud from vtk to ply format using Paraview). I would like to try the "build surface from point" but when i "click" on the button in the menu nothing happen! Is this normal? i'm forgetting something? third: my points-cloud is in the format x,y,z,I where I is the value of reflectance recorded by the LIDAR. It variates from 0 to 255. Is it possible to use this value to colorize the points (and/or the mesh ill create)?? Like to say: black for 0, white for 255! And how can i control the dimension and shape of the points?

Hi Paolo, When processing a .v3d file, you can select multiple images to make the 3D reconstruction, and a button ³Export as PLY² is foreseen to create 3D models from each of the selected images/depth maps. When using this functionality, I discovered that the creation process of the 3D models does not take into account the cleaning process (remove small pieces, ...) for which the parameters are available in the V3D import window. The way I work is that I select the images to reconstruct from with a subsample factor of 2 or 3, alter the import parameters as needed and when those settings provides me with a satisfying result, I decrease the subsample factor to 1 and do ³export to PLY² Best regards and many thanks Daniel -- Ir.

Hello Paolo, I noticed when cleaning 3D models that originate from processing a .v3d file (coming from Arc3D), there are always a large quantity of unreferenced vertices. I think this has to do with the cleaning process that removes small pieces, which forgets to delete the vertices of the pieces that have been removed. When I don¹t tick the box ³remove pieces less than...², there are no unreferenced vertices. Is there a reason to keep these vertices, although the polygons are removed, or is this a small bug ?

Hi Paolo, I¹m currently using MeshLab to prepare a demonstration for a project, and I came across the following bug : * I create different range maps from the ARC3D data and load them as .PLY files in Meshlab * I edit one of them (by using the Layer Dialog window) * I save the one that is highlighted in the Layer Dialog * if I overwrite the existing .ply file by the new edited file, the programme crashes, if I save the result under a new name, there is no problem The problem is independent of the file content and the edit actions (I think, did some testing) Best reagards, many thanks Daniel -- Ir.

UPDATE: eventually I managed to workaround the second incompatibility I listed about Transpose (but that does not means you should not care about updating them ;), see my remarks ) So, it remains only the dot product as the unique incompatibility. gael.

Hi,
In the subversion tree there is a trunk folder, but no branches or
tags folders. Which version of the source code was used to make
MeshLab v1.1.1?
Are changes on the trunk considered "experimental", or are they tested
before being committed?
Will tags be created for subsequent releases so that I can update my
source at the appropriate time? I don't want to keep tracking the
trunk if the functionality is unstable.
Thanks!

Dear all, for your information all the changes I made in vcg related to matrices and points are enabled only if you define VCG_USE_EIGEN. Since 2 minutes or so, meshlab compiled with that token on the following three platforms: - linux, gcc 4.3 - linux gcc 4.0.1 (= mac's version + epsilon) - msvc 9.0 This token is now defined by default in meshlab. If you really have big troubles, then edit the files shared.pri and meshlab/meshlab.pro to remove it and, please, send me you compiler errors. In order to allow for a smooth transition, the goal was to try to keep a source compatibility with previous matrix/point classes once VCG_USE_EIGEN defined. In practice this was not entirely possible, and here is the list of the major issues you might have while enabling VCG_USE_EIGEN: - first of all make sure your code compile without it. In particular we had to change Point*::Zero() to the more explicit SetZero(). Remind that p.Zero(); set p to zero. Once VCG_USE_EIGEN is defined, p.Zero() will still compile but it will do nothing ! Indeed in Eigen, Zero is a static member function which returns the expression of a zero matrix or vector. For consistency I've also changed the few other Zero() functions which actually performed a "set *this to zero", a big regexp replacement should do the job in most cases. - the second major difference is that the dot product is no longer defined via the operator*. Instead use p1.dot(p2). Perhaps we can also add a global function vcg::dot(p1,p2) if some of you would prefer such a syntax. Fortunately those errors are caught at compile time: you should first get some weird messages stating that it cannot convert a Eigen::Product<...> to a scalar followed by the very explicit: invalid_vector_vector_product__if_you_wanted_a_dot_or_coeff_wise_product_you_must_use_the_explicit_functions - the third and last incompatibility is with respect to m.Transpose() and vcg::Transpose(m). I cannot provide such functions because Transpose is the name of a class in Eigen. The quick fix is to replace them by either: * m.transposeInPlace() if you really want to transpose the matrix you have in hand (it returns nothing). * m.transpose() if you only want to use the transpose of m (it does not change m, and returns a transposed expression) If you want to be a bit smarter, you should also check for code like that: Matrix33 mt = m; mt.Transpose(); m * mt; which should be replaced by the more efficient and intuitive: m * m.transpose(); Note that those 2 functions also work if VCG_USE_EIGEN is not defined. - finally I removed a couple of things which seemed to be used only internally by vcg math classes like MatrixDiag*, and LinearSolver. Again fell free to contact me if that's a major problem for you or if you are unsure about how to work around. These 3 modifications are the only ones I had to do to make meshlab compatible. So you have some troubles please report them to me. Once you've done that you can start using Eigen's API which is available trough all Matrix and Point types. Of course, this is only the first step towards this major change, more to come later... cheers, gael.

Dear Developers, as you could have noted, some major changes happened to our VCG library: the currently very chaotic, buggy, and incomplete math folder is going to be replaced by a clean, documented and efficient template library for linear algebra (vectors, matrices, and related algorithms): Eigen ( http://eigen.tuxfamily.org ) You should have seen a new folder in the vcglib repository, eigen, this folder is a SVN direct link to the repository of eigen, so you have no write permission on that folder (you have to be a eigen developer to commit stuff there). More details on these changes later. In the meantime, if something stop compiling, dont panic :) I wish to thank warmly Gael Guennebaud, a core developer of eigen, for suggesting and implementing this change (and obviously for all his point related contribs inside meshlab :) ) Cheers Paolo -- Paolo Cignoni -- Senior Researcher Visual Computing Laboratory - ISTI - CNR http://vcg.isti.cnr.it/~cignoni ISTI - CNR Via Moruzzi 1, 56124 Pisa ITALY |

Hi, Sebastian: thanks for your wonderful work of the phototexturer plugin. Actually I'm not working on the point based models but the meshes with faces. I think it will be wonderful if the photo texturer have these functions: 1. face triangle which can be seen from different views can be fused together, using some weights (such as normal difference of the camera and the face) in different frequency (such as: low frequency averaged, high frequency winner takes all) 2. using texutre atlas to make the commbination method better, we can merge the uvtriangles into one texture image, we can use mesh parameterization method to make nearby triangles neighbors. the phototexturer plugin is so important, hopefully it can become more powerful and wonderful. o(∩_∩)o 2008-10-28 shubo 发件人： Sebastian Herholz 发送时间： 2008-10-23 21:11:50 收件人： Meshlab development list 抄送： 主题： Re: [Meshlab-devel] have the plugins "texture atlas" and"phototexturer" finished and why can't find them in r Hi bshu, I am the guy who is responsible for the phot texturing plugin. I didn't had so much time the last weeks to continuing working on it, But I have more time for it now. It seems that you are are working only with point based models, which doesn't have any faces, am I wright? Atm the plugin is designed to work with faces.

I have similar problem here, removing the splatrenderer fixed the issue. I really don't know what's going on. it stopped working very very recently while I did not change anything in it... gael On Fri, Oct 24, 2008 at 4:00 PM, Paolo Cignoni <pao...@is...> wrote: > Hi, > Is this happening also with the latest betabuilds? > > http://meshlab.sourceforge.net/wiki/index.php/Betabuilds > > > Or it happens only with your compiled version? > What platform/compiler? > > We have recently changed a bit the interface of the plugins, > so if you still have some old plugins in the meshlab plugin folder that > could crash it before the complete start. > > Do you have an offending ply available? > > (BTW collada importer could have some problems, but only collada files > should be affected, all other io plugins should be ok). > > cheers > p. > > > > Geert Willems wrote: >> Dear all, >> >> I'm running into problems with the latest revision: >> - including all the plugins, meshlab segfaults before the window pops up >> - when only keeping the IO plugins in the folder, I have problems >> importing ANY of my previous models (collada, ply, ...). >> I consistently get: "Warning mesh contains ... vertices with NAN >> coords and 0 degenerated faces.

Hi, Is this happening also with the latest betabuilds? http://meshlab.sourceforge.net/wiki/index.php/Betabuilds Or it happens only with your compiled version? What platform/compiler? We have recently changed a bit the interface of the plugins, so if you still have some old plugins in the meshlab plugin folder that could crash it before the complete start. Do you have an offending ply available? (BTW collada importer could have some problems, but only collada files should be affected, all other io plugins should be ok). cheers p.

Dear all, I'm running into problems with the latest revision: - including all the plugins, meshlab segfaults before the window pops up - when only keeping the IO plugins in the folder, I have problems importing ANY of my previous models (collada, ply, ...). I consistently get: "Warning mesh contains ... vertices with NAN coords and 0 degenerated faces. Corrected" The viewer shows nothing. When I then try to remove all unreferenced vertices, the number of vertices becomes _negative_. Does anyone experience similar problems?

hi,
for all poor owners of an ATI card, good news: (quoted from rev 2851):
Eventually the splatting renderer works on ATI too. Well the driver
still contains
a lot of bugs, so there is no high quality, and it is rather slow. So
the drivers bugs are:
- gl_FragCoords does not work with point primitive => quite expensive
workaround
to retrieve the coordinates of the fragments
- blending + floating point buffers => values are clamped to [0:1]
=> the buffer might overflow if too many splats accumulate on the same pixel
=> no deferred shading (because the normals have to be signed)
Anyway it is still better than nothing !
cheers,
gael.

Hi bshu, I am the guy who is responsible for the phot texturing plugin. I didn't had so much time the last weeks to continuing working on it, But I have more time for it now. It seems that you are are working only with point based models, which doesn't have any faces, am I wright? Atm the plugin is designed to work with faces. If you are intresseted I could add the opion so that it works on points only. Greetings Sebastian 2008/10/18 bshu <bs...@ic...>: > Hi, Paolo, > > thanks for the reply.

Hello, Oscar
I have found the pickpoint plugin does not crash on meshs with faces, but will crash on meshs without faces, and it crash at file grid_util.h:
template<class scalar_type>
void BestDim( const __int64 elems, const Point3<scalar_type> & size, Point3i & dim )
{
const __int64 mincells = 1; // Numero minimo di celle
const double GFactor = 1; // GridEntry = NumElem*GFactor
double diag = size.Norm(); // Diagonale del box
double eps = diag*1e-4; // Fattore di tolleranza
assert(elems>0); //crash on this line, the elems is 0, does it mean this plugin only works on meshes with faces?
assert(size[0]>=0.0);
assert(size[1]>=0.0);
assert(size[2]>=0.0);
this is the memory trace, hope useful:
> edit_pickpoints.dll!vcg::BestDim<float>(const __int64 elems=0, const vcg::Point3<float> & size={...}, vcg::Point3<int> & dim={...})

Hello,
I am responsible for the pickpoints edit plugin. I have tested it extensively on windows with minGW compiler and on linux with g++ and have found no problems. Could you please tell me what exactly you did to make it crash? Saying just that there is a bug does not help solve it. Here is some information on how to report bugs effectively:

Hi, Paolo,
thanks for the reply. I'm using meshlab for a while and find it's so powerful and wonderful, but have some problems, maybe I did not find some functions:
1. save a mesh to ply, is it possible to only write out the vertises, and do not save out the face? because i found it's quite useful
2. is there a plugin select vertexs in a region similar to the plugin "select faces in a region"?
3. the pickpoints edit plugin crashes
4. the texture atlas plugin just write the whole textures into the atlas, but the recent methods use facewise method so that the part of the images which do not correspond to any mesh face will not be written into the atlas. Is this method implemented yet? if not, any plan for it?
5. I have looked through the code of some plugins and found that some codes are using dynamic arrays in such form: int a[x], where x is a variable, i think this is not in standard c++ format and it does not pass the compliation on my computer (which is visual c++ 2003), is it because of the wrong settings of my development tool?
thanks a lot for the wonderful meshlab tool, hope meshlab will grow bigger and have more users. hopefully more people (including me) will contribute more and more to meshlab!

Dear all:
Does anybody knows about the process of the plugins "texture atlas" and "photo texturer"? Havn't seen any update since August. And I also can't find them in the meshlab release 1.2.0.
Does anybody know that the work <Masked Photo Blending:mapping dense photographic dataset on high-resolution sampled 3Dmodels> of Paulo implemented in vcglib or the photo texturer plugin, if no, does anybody has a plan on that? Thanks very much!

Yes, TextureAtlas filter still has some issues. So we will work on it later, after the very delayed 1.2.0 deployment...
and yes, we plan in the next future to make grow the current phototexturing plugin into the technique described in the above cited paper.
cheers and thanks for the comments.
