Hi,

first results:

Align-tool is much more stable;

U3D export works without any problems at Win XP. Now you have the possibility to set a quality value. The u3d appeares less reflecting/shiny than the result of DAZ-Studio.

I've done a comparison: DAVID vs Meshlab: Aligning and poisson fusing with the maximal quality, using the same meshes. Results are nearly equal, but DAVID wins for its automatic modes and command-line-interpreter: DAVID is faster and can be automated. But you can get similiar results using Meshlab if you are a little patient....

I have to link to the Wiki again, for the forum doesn´t allow pdf bigger than 1MB:

download the pdf at:
http://www.david-laserscanner.com/wiki/user_page/magweb/davidvsml

By the way @ Simon and Sven:

Could you rise the allowed pdf size a little? ( Seems that 1.5 MB would allow to embed 2 u3ds of medium quality or one little more detailed) --- Would be great---For now that pdf way is much more simple, free and universal.

problems

Postby erniej » Mon Mar 24, 2008 6:10 pm

I hate to be the "fly in the ointment" but I still receive crashes during alignment. I am running Vista Home Basic.

Update: I just tried point based alinging and I received good results.

Question: How do you save the combined meshes? I tried to do this but when I re-loaded the file I was missing one of the objects..

Hi Erniej,

I wrote intentional "much more stable"... eg if you run load 16 huge scans and click "process" after every glew the tool crashes glewing the 11th mesh...seems to be a memory problem...

The process in general:


1.Step
-Open all needed meshes in one project by marking all in the open dialog;
-Activate the Alignt tool clicking on the A button;
-Choose one mesh to start from in the upper list of the AlignTool window . This one is the only one not being moved in the following process.
-Click on "Glue mesh here"---> A little star behind the meshname shows that this one is glued/ fixed in its position

2.Step
-Click on one next mesh, you want to align, in the upper list
-Click on "Point based glueing"

3.Step
A new window opens:
At the right: the allready glued mesh(es) At left the mesh you wish to glue onto the right.
-Rotate the left mesh dragging it, so it shows rather its needed aspect in relation to the right mesh.
- Double click LMB on a charateristic point of the mesh at the left. ---> a small red zero appeares.
- Double click LMB on the coresponding point on the right mesh. ---> a little blue zero appeares.
-repeat this step several times to get at least four corresponding pairs of points
-Clicking OK the window closes and the red poits are aligned to the coresponding blue points.

-Repeat Step 2-3 till all meshes are glued and signed with a little star.
This step is similiar to Shapefusion's "Manual Align" mode .

4.Step
Finaly click Process ---- Close Align tool----

5.Step
Run Filter: Flatten visible layers

6.Step
Run Filter: PoissonReconstruction ---- done

Note: Running the Poisson filter you loose your align result. So if you wish to try different resolutions (octree depth) "save as" before running that filter.

Meshlab is a great tool, but after trying the A-tool several times I think this aligntool is not an equivalent to Shapefusion. You may try, but you´ll return soon.

Please report.

Gunter

EDIT:

Noticed your update after posting mine:

thanks MagWeb

I found out how to flatten all the layers. Meshlab does a nice job.
