3DF Zephyr 5.0 is finally out!

What’s new in 3DF Zephyr 5.0?

With this update 3DF Zephyr is significantly faster than all previous releases and the quality of the reconstruction is now significanlty better: the new photoconsistency filter allows for much more beautiful and realistic sharp edges, the out of core new algorithm allows to process huge datasets at a much lower memory footprint, and our world-class texture algorithm now produces even sharper and better textures.This is the biggest technology update that 3DF Zephyr has ever received in a single release, and as tradition, all 3DF Zephyr versions (including Free and Lite) are getting the same technology improvements.

3DF Zephyr Pro and 3DF Zephyr Aerial have now been unified into one single software solution, called 3DF Zephyr.

3DF Zephyr Free and 3DF Zephyr Lite are still two separate products. Make sure to check this page for more information, especially if you are a 3DF Zephyr Pro license holder.

Speaking of licensing, while 3DF Zephyr is still available as lifetime license, we also added a subscription based option, which allows you to rent 3DF Zephyr monthly – visit zephyr.3dflow.net and purchase your subscription via FastSpring.
The subscription renewal is optional and you can cancel anytime directly from FastSpring.


The subscription is great for those professional who do not need Zephyr on a daily basis, but do some photogrammetry work every now and then – in that case, you can purchase Zephyr only when you need it.


Please note that like the perpetual license, .zep files are absolutely not locked in any way – you will always be able to get back to your work, on any pc you have 3DF Zephyr installed on. The Zephyr project files can be opened with any version of Zephyr, including Free and Lite.We understand the importance of having a modern and reliable workflow, so as usual also this updates adds many more tools and feature to the 3DF Zephyr toolset:

3DF Scarlet is a new, standalone software that is bundled at no additional cost with 3DF Zephyr 5.0 for laser scan registration: while you can still use the previous workflow you have learned in 3DF Zephyr, you may find 3DF Scarlet better suited to the task: designed from the ground up, it handles much bigger datasets than 3DF Zephyr for laser scan registration, it has dedicated tools for the tasks as well as a new automated registration feature. Make sure to try it out!
3DF Zephyr now integrates WIC for faster image loading and better raw file format support – make sure to install the WIC raw plugin first, or Zephyr will fallback to the previous imaging engine.


3DF Zephyr is now also available in the Turkish and French languages, and among the many quality of life improvements we have a new toolbar to improve productivity, spline support in drawing elements, updated native laser scanner support plugins, and much more: make sure to check this link for a more descriptive changelog.

If you had 3DF Zephyr installed, you will receive the update as usual automatically via the autoupdater feature, otherwise you can always download it from 3dflow.net as usual.

We’d like to take a moment to thank all our beta testers, who helped making 3DF Zephyr a better software – thank you for all your feedback and patience!

We’re extending the summer sales event!

3DF Zephyr Lite (perpetual) licenses and 3DF Zephyr (perpetual) licenses can be purchased with a 20% discount from 3dflow.net and the new 3DF Zephyr subscription can be purchased with whopping 50% discount for the first month – get these deals while they last, from today until July 21st, 2020!
