3D SHAPE GmbH - 3D data processing controlled by script or DCOM

SLIM^3D 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:


Registration	Coarse Alignment Error Minimization in Pairs Global Error Minimization

Mesh reconstruction	Triangulation Filtering Thinning Subdivision Completion

Visualization	3D Display Data Analysis Mesh Editing

In addition to its convenient user interface, SLIM^3D 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, SLIM^3D is fully controllable by DCOM function calls and thus seamlessly integrable into other programs.

System requirements:
SLIM^3D 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.

Further details can be found in the PDF file of the product flyer.

Reverse Engineering Software

SLIM^3D 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 SLIM^3D 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.

Registration

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

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.

Visualization

The SLIM^3D 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.
