Visualize, explore, and quantify your data with Dragonfly Pro

Dragonfly Pro from Object Research Systems (ORS) is an advanced analysis software solution for 3D data acquired by a variety of technologies including X-ray microscopy and FIB-SEM. Using advanced visualization techniques and state-of-the-art volume rendering, Dragonfly Pro enables high-definition exploration into the details and properties of 3D datasets. It offers 2D and 3D image filtering modules and thresholding. Segmentation can be performed automatically or with user assistance generating 3D surface reconstruction to visualize and measure properties, including areas, volumes, counts, distributions, and orientations.

Dragonfly Pro delivers cutting-edge 3D imaging and analysis techniques with high display speeds and the ability to handle large datasets.

Customize with Python scripting

Dragonfly Pro now enables Python scripting - a powerful feature that allows users customize their data processing and visualization needs. Users now have access to the data channels and properties within the interface creating a limitless post-processing environment.

Easy to use

Dragonfly Pro is easy to use. With minutes of experience, you can explore, navigate, and annotate your dataset. In a few hours, gain control of more advanced tools such as image processing, segmentation, object analysis, and movie making. Use our compact, topic-specific training videos to familiarize yourself with Dragonfly Pro in the shortest amount of time.

Visual SI Advanced Customers have access to Dragonfly Pro!

Existing Visual SI Advanced Customers have complimentary access to the initial version of Dragonfly Pro. Both software packages will run independently on your Visual SI Advanced workstation as you make your transition to Dragonfly Pro. Keep your Visual SI Advanced software running as long as you like, it is a perpetual license. However, all feature improvements and continued development will be performed on Dragonfly Pro. We encourage you to transition and be part of its Python functionality and growing user community!

As an existing user, getting started is simple:
  • Download the Dragonfly Pro trial installer from this website onto the workstation that runs your activated version of Visual SI Advanced
  • Upon installation, the Dragonfly Pro software will activate via your existing license key
Be sure to view the newly-produced Dragonfly Pro training videos. All topics from Visual SI Advanced have been reworked in the Dragonfly Pro interface. There are additional training videos available that showcase new features that Dragonfly Pro has to offer. Please begin with the Quick Start Basic Training.

Existing Visual SI Advanced Customer FAQs:

I'm an existing VSI Advanced customer without a current annual maintenence contract. Can I still get Dragonfly Pro?
Yes, regardless of where you stand with your annual maintenence contract, you have complimentary access to the initial version of Dragonfly Pro. This does not reactivate or extend the terms of your maintenance contract.

Do I need to upgrade my workstation to support Dragonfly Pro?
No, Dragonfly Pro will run on your existing Visual SI Advanced workstation with dedicated professional graphics. Please note that Dragonfly Pro is not supported by integrated laptop graphics.

Do I have to run Dragonfly Pro on the same workstation that runs Visual SI Advanced?
Yes, Dragonfly Pro must be run on the same workstation as you are currently running Visual SI Advanced. If you need to transfer to another workstation, transfer both software through the activation/deactivation process.

Do I still have access to the Visual SI Advanced training videos?
Yes, they can be found on the training videos tab of this webpage

Can I still buy additional licenses of Visual SI Advanced?
Yes, contact your ZEISS sales representative. Please note that additional feature developments will be performed on the Dragonfly Pro platform.
