Introduction Reverse Engineering Software
Registration Mesh Reconstruction Visualization

3D data processing controlled by script or DCOM

SLIM3D makes it possible to create a complete high-precision model from
a set of different single 3D views. This Process is made up of three pro-
cessing steps:


Coarse Alignment  
Error Minimization in Pairs  
Global Error Minimization  

  Mesh reconstruction



3D Display  
Data Analysis  
Mesh Editing  

In addition to its convenient user interface, SLIM3D offers the possibility to run the processing steps almost entirely automatically via Visual Basic® Script. Interactive control is only required for adjusting the parameters if a new class of objects or a new 3D sensor is used. Moreover, SLIM3D is fully controllable by DCOM function calls and thus seamlessly integrable into other programs.
System requirements:
SLIM3D runs under Windows® NT/2000/XP and requires at least a Pentium® 4 processor with 1024 MB RAM and a minimum of 300 MB free hard disk space.

Reverse Engineering Software

SLIM3D is a program package for processing the data from optical 3D measuring systems for
- Reverse Engineering
- Virtual Reality
- Rapid Prototyping
The generation of a complete model from the individual scans is achieved with previously unattainable quality, which is decisive for applications in, e.g.
- Mold making
- Medical applications
- Preservation of historical buildings
A 30 days trial version of SLIM3D is available for evaluation. Please contact our software support (sw-support@3d-shape.com). Your email address will be kept confidential and not distributed to any third parties.


In registration, the depth images of different views of an object are aligned to one another without needing to know the scanning position or the sensor type. An automatic coarse registration step makes it possible to place the sensor in any desired position around the object and so ensure that there is no missing data caused by occlusion or shadowing. If automatic registration does not yield satisfying results, an interactive alternative can be used. For this, corresponding features such as object corners or significant textures are marked by the user in the overlapping areas of different scans.
Remaining surface deviations in the overlap regions are then minimized by a fine registration procedure.

Mesh Reconstruction

Mesh Reconstruction
The aligned depth images are then converted, fully automatically, into triangle meshes and cleaned of noise, aliasing and outliers.
Next, the meshes for the different views are merged into a single surface description. Any interference that appears owing to registration or calibration errors is then filtered out. Finally, any gaps that are present are closed using interpolation in a fully automated process, and curvature-dependent mesh thinning is carried out.


The SLIM3D software package contains the powerful 3DViewer visualization and mesh editing tool as a stand-alone program.
The 3DViewer is a program enabling the three-dimensional visualization, analysis and editing of 3D data from optical sensors. The available display modes are point, wire frame or surface view (flat or Gouraud shading), and cross-sections profiles can be created for any cutting planes. In addition, the software allows interactive data editing.
In addition to the flexible proprietary data formats the program also supports import/export of common mesh formats such as STL, OBJ, 3DS, DXF, WRL etc.
