{STEAM_CLAN_IMAGE}/11732295/748ba2a7bf0541b3f54f52029d145f6642f4445e.jpg 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. This update is free for 3DF Zephyr Lite Steam Edition too! 3DF Zephyr now integrates WIC for faster image loading and better raw file format support - make sure to install the WIC native 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.

Good news, everyone! 3DF Zephyr 4.500 is ready for download! https://steamcdn-a.akamaihd.net/steamcommunity/public/images/clans/11732295/20a63f44fe805c513b3b27ebd241e03d85dee83c.jpg So what’s new? A lot of improvements, as usual, in both the core technology and the user experience as well! This major update took a little longer than you’re used to, but we really think it was worth the wait! The core technology now yields even better results than before, with an all-new detail enhancement filter for mesh, a new UV-packing algorithm, and much more!

Faster processing - both the Structure from Motion and the Multiview stereo phases have been significantly improved: for the SfM phase, the bundle adjustment has been improved for dealing with very big datasets and the speedup is especially significant when using more than 500 photos during the orientation phase. As for the MvS phase, the depth map generation was the slower part of the pipeline and we have improved it a lot using novel techniques. Better detail - Our multiview stereo routine has been improved in several parts and it can recover even more detail than before. Improvements have also been made in the photoconsistency algorithm, which can now deal better with thin structures. Knife cut tool - You can now cut through mesh triangles using planes (or bounding box) for a much more beautiful results Improved UI and new bounding box - Many tools have been reorganized for a much more efficient workflow and an even cleaner UI design - to top it off, 4.3 also features a new improved bounding box and gizmo. Export self-hosted 3d model - Quickly embed your 3D model on your website using this HTML/JS exporter. CUDA 10.0 - Zephyr has been upgraded to use the latest NVIDIA CUDA toolkit, 10.0. This allows supporting the most recent cards. Please note that with this improvement, the support to older cards (CUDA capabilities < 3.0) has been dropped. Make sure to update your drivers! Please note that if you are using a very old NVIDIA card, you should still have better performance now even in CPU (when compared to very old nvidia cards). If you have any question on this matter, simply contact [email protected] https://www.youtube.com/watch?v=uGO2ex_GsaY Full changelog:

Good news, everyone!! 3DF Zephyr 3.300 is finally ready! As usual, we pushed our state of the art technology to the next level, added new tools and fixed many minor annoying bugs! What's new in 3.300?

• Improved technology

This update allowed us to release many speed optimizations we have been developing for a while: our multiview stereo algorithm is now usually 50% faster compared to v3.201 (especially increasing the number of pictures, as it is optimized for big datasets). Our structure from motion algorithm has also been improved, with a faster (and even more accurate) rematching phase as well as our photoconsistency based optimization. Did we sacrifice accuracy? Of course we did not! In fact, v.3.300 is also even more accurate than ever before!

• New tools

We always listen to feedback and we managed to sneak in many new tools that should streamline your workflow even more. You can now for example apply mesh filters on mesh selection (for example, you can optimize the topology of a certain part of a mesh). There was also room for other fixes and improvements, as usual: see the log below for more information!

• Summer Steam Sale!

Of course 3DF Zephyr is also part of the traditional Steam Summer Sale! You can get 3DF Zephyr Lite (Steam Edition) with a 33% discount! Head over to our Steam Page to purchase it while the offer lasts, and don't forget to share your reconstruction in the community hub :) Full changelog:

• Improved optimize camera parameters and alignment to control points worflows on failure (problematic cameras are now detected and can be removed from the dialog).
• Rematching can now be cancelled or paused during bundle adjustment and alignment steps.
• Zephyr can now be deactivated also if you are offline. (Non Steam only)
• Stereo improvements and preset balancing
• Photconsistency mesh optimization speed improvements
• Selection tools improvements
• Camera positions can now be added as control points
• Stereo texture can now been unstructured
• Added image overlap in the processing report
• Gizmo can now move entire objects only in rendering
• Added chinese language support
• Sparse point cloud generation improvements (rematching accuracy improved)
• Stereo point cloud generation improvements (speed and accuracy)
• Fixed a bug during mesh generation (small parts are reconstructed better now)
• Fixed a bug in stereo point cloud generation
• Improved sketchfab upload
• Log and System info are now available as separate window from the progress bar
• added mesh filtering on selection (laplacian, bilateral, retopology)
• added triangle selection filtering by connected components
• elements name are now customizable (i.e. create a control point with "CP" label rather than "Control Point")
• Added clear cache button and additional memory checks
• Update Ogre Engine
• Added option to toggle rendering "fog"
• Impoved rematching phase
• miscellaneous bug fixes

3DF Zephyr is as usual available as Free and Lite over the Steam Platform. More information are available at http://zephyr.3dflow.net

Happy Pi Day! To celebrate, we have released 3DF Zephyr 3.141! * + Added hardware monitor window + Fixed a bug in sketchfab export + Fixed a bug in remeshing with no cameras loaded in export + Fixed a bug that would crash zephyr when renaming certain textured meshes + Fixed a Qt related memory issue in the log panel + Tiff file loading speedup (can be disabled in application options) + Minor UI fixes * there has been an internal debate, whether should we use an additional decimal or the round up approximation. We went for the additional decimal value.
