[Meshlab-devel] Warning: change of the rendering loop of the glarea

[Paolo C. <pao...@is...>]

*** WARNING interface changes ***

The main rendering loop of the glarea has been significantly rewritten. 
I have updated all the rendering plugins that now mostly work.
Main Changes:
- Rendering plugins are now responsible of the rendering of the whole 
MeshDocument and not only of a single MeshModel. This means also that 
multipass rendering techniques are more streamlined. The only 
requirement for a rendering plugin is that it should leave the z-buffer 
in a coherent state.
- The scaling/centering of the scene is now devoted entirely to the 
trackball (for a future better camera management)
- The trackball is post-drawn (now it is nicely antialiased against the 
mesh)
- The snapshot mechanism has been improved (now works for ortho 
projections too)

cheers
P.

Hi,

I have downloaded the latest version from SVN, compiled it, and am halfway 
through writing the IO plug-in (vertices and faces load, texture coordinates 
remain). Everything seems to be working properly so far. I guess the problem 
was incompatible versions of qt and/or mingw.

So then, if I want to compile a DLL that I can just distribute that will 
work with the version that is available from sourceforge (1.1.1), I just 
need to find the right version of the qt sdk to compile it with. From the 
DLL info, it looks like that's qt version 4.3.3.0 and whatever mingw 
compiler was distributed with that.

What I am writing is related to the Photon-X sensors. Basically we have a 
very small raw 3D format that takes advantage of the way a mesh is generated 
from our cameras. It's less than 5% of the size of an OBJ, both of which 
store vertices, normals, and texture coordinates for meshes containing 
potentially millions of vertices. I was hoping to be able to view (and 
possibly manipulate) these files inside of Meshlab.

Thanks for your help,
Randy

Hi,
as a first note i strongly encourage you to directly compile the 
development version of meshlab.
Is fairly stable, and much much easier for us to support you....

Then coming to your issue i think that to allow the loading of 
additional plugins to the distributed version of Meshlab you have to 
exaclty match not only the compiler but also the qt version otherwise 
the qt plugin mechanism could create issues...

Just a curiosity,
Is the importer that you are writing something rlated to the Photon-X 
sensors?

That's a typo in the original message. I meant to say (qmake -recursive 
meshlabv11.pro && make release).

[Meshlab-devel] Meshlab plugin detection

[Randy <ra...@ph...>]

Hello,

I'm attempting to write an IO plugin for meshlab. I've downloaded the 
sources for version 1.1.1, and started development. I am able to 
successfully compile everything under Windows using the mingw gcc compiler 
(qmake -recursive meshlabv12.pro && make release). However, whenever I try 
to move the plugin (or any other plugin compiled from source) to the plugins 
folder of the meshlab version installed from the setup executable (also 
version 1.1.1), the DLLs are not recognized. If I remove all DLLs that were 
installed from the exe, and put in their place DLLs that I compiled, Meshlab 
gives me the error of "Can't find any plugins in the C:\Program 
Files\VCG\Meshlab\plugins directory" when I go to help->about plugins. Any 
idea of what I might be doing wrong, or what other information is required 
to debug this problem?

Thanks for your help,
Randy 

[Meshlab-devel] Does meshlab have any mesh parameterization features?

[bshu <bs...@ic...>]

Hi, guys

   Does meshlab have any features like mesh parameterization, similar to seamster algorithm. This is a quite basic mesh operation which I think is useful for meshlab. or does anybody have any plans to implement this into meshlab?　thanks!

best wishes ! ~ o(∩_∩)o

[Meshlab-devel] phototexturing_plugin

[Sebastian H. <seb...@go...>]

Hi guys,

Sorry that there where not so many updates of the phototexturing
plugin lately but I got assigned to another project for the last
two month. Now my boss reassigned me to meshlab and I will continue
working on the photo texturing plugin.

Here is a list of functions wich are supported at the moment:

-loading Tsai camera clibration data for several cameras (xml format)
-calculating the uv coords for each loaded camera (including z-Buffer)
-merge textures of different cameras using the angle of each face to the cameras

If the loaded mesh already has uv-coordinates it is possible to bake
the textures. that means all calculated camera textures are unproject
to the given uv-coords then these unprojected textures for each camera
are merged (baked) together to one texture.

For this baking process of the textures are two methods available jet.
Winner takes all:
-the pixel with the best angle to a camera is chosen.

smartblend:
-the texture images are merged using the smartblend.exe tool (command
line tool: Windows: "smarblend.exe" Linux Mac: "wine smartblend.exe")

What is still missing is an interface to calibrate a camera using
2Dcoords of the texture image and corresponding 3D points.
The functionality is there but an interface is still missing to
collect these points.

If anybody has some suggestions on what to add to the tool ore who to
bake the textures of the different cameras please tell me.

Greetings

Sebastian

Re: [Meshlab-devel] [SPAM] Are plugins filter_texture andedit_phototextureing still updating?

[Sebastian H. <seb...@go...>]

Hi bshu,

I also found out that the poisson makes some problems sometimes. The
biggest one is that you can use it only onec in a meshlab session. If
you are using on two similar meshes without closing meshlab inbetween
you are getting a different result. I think the problem could be that
some settings or temporary data is not reset in the original Poisson
source code. I tried to look for it but I couldn't find anything.

A detph of 12 is really high for 500.000 points. It may be memory allocation.
what kind of system are u using? 64Bit Win/Linux or Mac?

Re: [Meshlab-devel] [SPAM] Are plugins filter_texture andedit_phototextureing still updating?

[bshu <bs...@ic...>]

paolo,
  
  Thanks! I found some problems about the filter_poisson plugin. I used the release version of 11.28. the reconstruction results is different from the results I use the poissonrecon.exe download from Kazhidan's website and the exe I make with the poisson source code. I use the same version (v2) of the poissonrecon exe as meshlab bases on. The reconstructed mesh from meshlab seems that some parts of the object misses or flattened. Does the problem comes from a compiler setting difference or some code difference, such as 'float' and 'double' presion differences? 

  Another problem of poisson filter is that meshlab crashes when I use a high depth, such as 12 on some point sets, which works well on the poissonrecon.exe. Does it come from the memory allocation? my point set has about 500,000 points.

There're also some problems on phong splatting plugin. It worked on the source code I compiled about two months ago. But also crashes on the same point sets I used before.   

  
best ~ o(∩_∩)o

yes unfortunately they lie in a rather sleepy state. 

The filter_texture will surely be restarted in a short time. 

the PhotoTexturing editing tool would probably need a more detailed implementation plan.
We feel texturing from photos abilities a very important fieature so be sure that in the next future this set of functionalities will be broadly expanded....

Re: [Meshlab-devel] Update of the problem with vcglib and PLY files

[Jacob M. L. <ja...@im...>]

Hello

Thank you, that solved the problem, I was confused since the message  
from Xcode was different. I could also fix the Xcode project by adding  
only the plylib.cpp file, instead of all the vcglib.

I tried to compile the samples using

qmake -recursive samples.pro

But the Xcode projects generated have the same problem, the only one  
that compiled (in Xcode) was trimesh_attribute. Compiling from  
terminal has no problems.

In fact, following the instruction to compile meshlab:

  qmake -recursive meshlabv12.pro
make

I got the following

make: *** No targets specified and no makefile found.  Stop.

The Xcode projects generated by qmake present the same problem. Some  
work and others don't. Meshlab project compiles and executes the app  
but I can't do anything with it since it doesn't recognize any mesh  
file. Quite strange.

Regards

Jacob

Re: [Meshlab-devel] Update of the problem with vcglib and PLY files

[Paolo C. <pao...@is...>]

The undefined symbol error means that you have not linked something.
Precisely it seems that when you compile your code you should add to 
your project also plylib.cpp (that you can find in the vcglib/wrap 
directory.

once you link it the problem should disappear.

Have you successfully compiled the samples under the vcglib/apps/sample 
directory?


cheers

[Meshlab-devel] Update of the problem with vcglib and PLY files

[Jacob M. L. <ja...@im...>]

Hello

It's me again, looks like the problem I'm having with the vcglib is  
not from Xcode. I tried to compile from terminal with no success.  
Actually I changed the location of the vcglib to /usr/include since I  
was using the location for Meshlab. Now I have different errors but  
they are coming from the same part of the code.

Errors
Undefined symbols:
   "vcg::ply::PlyFile::PlyFile()", referenced from:

I'm using a MacBook Pro with MacOS 10.5.5

At this point I would like to use only vcglib instead of the full  
Meshlab, what do you recommend me?
Thank you

[Meshlab-devel] problem to open ply files (Xcode)

[Jacob M. L. <ja...@im...>]

Hello all

I'm having problems with the vcglib. Following the examples I created  
my own Xcode Project but I'm missing something. This is the code:

	printf( "Mesh has %i vert and %i faces\n", m.vn, m.fn );

	return 0;
}

-------------------

Xcode returns an error in allocate.h ????

/dev_code/vcglib/vcg/complex/trimesh/allocate.h:310: error:

I just added the search path in the properties of the project. If I  
add the files to the project (even without copying to the project's  
location) returns hundreds of errors.
I hope you can help me.
Thanks in advance.

I like the idea.
I have just added the integration of QHull code (that has a GPL 
compatible license) inside meshlab as one of the next projects.

[Meshlab-devel] convex hull

[Luciano B. <luc...@ca...>]

Hi all,
I would like to use Meshlab to compute convex hull 
(triangle mesh) of a points cloud (less than some hundreds 
points).
Anyone knows if is it already implemented such an 
algorithm in MeshLab or VCGlib?
If there is not, where is the right place to implement it 
(perhaps in a vcg::TriMesh method and use it inside a 
filter_convexhull i.e.)?
Could anyone advise me about the algorithm (Quick-Hull 
algorithm, Gift-Wrapping and Jarvis’s March algorithm, 
Chan’s Algorithm etc)?

Thanks in advance

Luciano

[Meshlab-devel] Colorizing a mesh

[Luca P. <luc...@em...>]

hello everybody,
	im working with meshlab from the svn. 
I am importing data from a text file (point data, xyz) creating obj
file. Can i add in this file a column for using it for colorizing the
model? I would like to assign the colours depending on this value. How
should i do?


thanks
Luca

Re: [Meshlab-devel] Problem compiling meshlab from svn code

[Luca B. <luc...@gm...>]

Hello Luca,
please report operating system and compiler version when reporting bugs :-)
I'm currently stuck with the same problem you are reporting, I'm using
gcc 4.1.2 under Gentoo.
I don't know why this problem arise, and I'm not trying to resolve it
at this time, because i'm currently working on non meshlab related
stuff.
I suggest you to checkout some older versions from meshlab and vcglib,
and to try the meshlab_mini.pro compilation (to save time). If it
succeeds, you can try to compile the full version, if it fails try
some earlier version.
Try to use synchronized versions of vcglib and svn.
Cheers,

L.

Afaik there's no Delaunay based algorithm currently implemented in 
Meshlab. Ball Pivoting works well for my datasets, I'm not quite sure 
about Poisson reconstruction.
If you plan to use the MLS stuff from the current development version, I 
suggest you wait until my question in the Sourceforge Help Forum[0] is 
answered, since at the moment my Meshlab always crashes when I try to 
reconstruction my selfmade objs.

Excellent!  That worked - thank you!  Can a mesh be built from the points - 
i.e. a Delaunay triangulation?  Most of the filters I try to run just result 
in crashes :-(.

Not directly, at least I didn't get it. I've "converted" simple xyz 
files (points only) to obj by just adding "v " at the beginning of every 
line. These did load very well.

I've not searched for that, but I did not find a list. I'd recommend to 
look at various point cloud software and see what they are able to 
handle. Personally I'd suggest you try ply files, I think these are 
relatively common (at least for academic software) because that's the 
format of the data in the Stanford scanning repository.

[Meshlab-devel] Two questions concerning point clouds

[Clifford Y. <cli...@gm...>]

Hi!  I'm interested in Meshlab's point cloud support, and I have two
questions concerning it:

1)  Import a simple file of xyz points into Meshlab, with an eye to building
a mesh from them (think basic surface scan)  - can it be done?

2)  More generally, does anyone know if there is a listing of various "point
cloud" data formats anywhere and how to convert to/from the various options?

Thanks,
C Y

Are you compiling the svn code? does it works well?
