| The 3D EBSD visualization software is a new dimension for Electron Backscatter Diffraction (EBSD). The OIMTM 3D Visualizer graphically renders serial data sets into a layered 3D model. The product was developed specifically for EBSD applications and is versatile to meet the microstructural characterization needs of the materials and mineralogical fields. Many of the standard two dimensional maps that have long been available in OIMTM Analysis are now easily utilized within OIMTM 3D. The information available through examining this extra dimension affords new insight into many important questions and at the cutting edge of today’s research. |

OIMTM 3D Visualizer Capabilities:
- Display sequentially collected data sets in 3D View 3D maps as individual layers or combined solid Split map at any location for detailed evaluation
- Extract any grain and display individually in 3D Select multiple grains based on color tolerance or user selection
- Show selected grains within a semi-transparent block Rotate, pan, and zoom the 3D microstructure
- Display the 3D data set using common OIMTM maps
- OIMTM 3D visualization functionality can be easily accessed from OIMTM Analysis with a click of the button.
- Datasets can be easily rotated and crosssectioned on three axes at user-defined locations
- Particular fields of interest can then be enlarged to view finer features

OIMTM 3D visualization functionality can be easily accessed from OIMTM Analysis with a click of the button. Datasets can be easily rotated and crosssectioned on three axes at user-defined locations. Particular fields of interest can then be enlarged to view finer features. One of the key features of OIMTM 3D is the ability to extract grains from the 3D microstructure and rotate the grains in free space. Several grain smoothing algorithms are available to refine the grain’s appearance.

The 3D EBSD Solution:
The application of OIMTM 3D with combined ion/electron beam microscopy has increased significantly in recent years. These advancements have been a direct result of skilled analysts and scientists having the freedom to work with the analytical tools of their choosing. EDAX offers powerful, yet versatile tools for EBSD data collection and analysis using the combined ion/electron beam microscope.
EDAX provides the OIMTM 3D Wizard which automates data collection set-up between the OIMTM software and the ion beam and SEM software interfaces, as provided by the microscope supplier. The 3D Wizard then initiates the scan and monitors the progress of data collection. The OIMTM 3D Visualization Software can be used to process the collected data sets into 3D representations of multiphase and textured structures.
If you're interested in user-customizable solutions to 3D EBSD rather than a Wizard-type approach, then the software development kit (SDK) and batch processing tools are still available for you to tailor to your specific experimental needs.
