3DF Zephyr Pro beta testing program

**Andrea Alessi** · 2014-03-31, 03:21 PM

We are currently fixing the known issues of v1.0083 (missing loading bar, MVS process abort time) and fixing new problems that have been reported in v1.0083.

So, if you are using beta v1.0083 please be aware that:

- extracted meshes might have "holes" if some visibility conditions are met (fix coming in v1.0084)

There are also two new known issues in v1.0083, both caused by the fact that the dense point cloud generations process has been rewritten recently.

- there have been reported cases of Zephyr crashing during the the dense point cloud generation phase (CUDA only)
- there are some scenarios in which the dense point cloud generation can be significantly slower than it should be.

We were expecting a few hiccups but everything is going smoothly towards the new release: hopefully these two fixes will be included in v1.0084 but it might take longer than a few days to test them thoroughly.

Lastly, there is also a minor new UI feature that allows the log to be shown in the loading bar window.

The new 3DF Zephyr beta version (v.1.0085) is ready for download.

Performance changelog:
+ color computation speed up in mesh and point cloud

Bugfix changelog:
+ fixed a bug with 4 channels tiff
+ fixed a bug in stereo computation (caused crashes with cuda)
+ fixed a minor bug in the texture generation process (improved accuracy)
+ fixed a bug in visibility computation (improved accuracy on orthophoto and texture generation)
+ fixed a bug in visibility computation that caused missing triangles (holes) in the extracted mesh
+ progress bar abort now working for MVS

Known Issues
- we are currently investigating small artifacts that may appear when generating textures

Next week we should release the stable release 1.009

The new 3DF Zephyr beta (v.1.0091) will be released today.

Here's the full changelog:

New features:

+ Added the parameters importing from xml (explanation and tutorial will follow).
+ Added a noise control for stereo computation.
+ Smoothness can be controlled more smoothly (via slider)

Fixes:

Beta version 1.0092 has just been released.
It contains a few important hotfixes:

+ Fixed a bug in surface reconstruction (improved accuracy)
+ Fixed freezes in surface reconstruction
+ Fixed a crash occurring during texture generation
+ Fixed multiband textures generation
+ Added a remesh checkbox to enable/disable remeshing when exporting a mesh.

**Roberto** · 2014-04-29, 12:04 PM

Version 1.0093 is out.

Changelog:

+ Removed duplicated vertices during texture exporting
+ Fixed normal computation problem for meshes
+ Added texture support for ply
+ Added check for opengl 1.4
+ Removed dangling vertices during texture generation

This is probably going to be the last beta version before the stable release.
