3DF Zephyr 6.0 by 3Dflow
3DF Zephyr 6.0 has a new Volume of Interest system that helps visualize very large datasets interactively, a new modular save structure, a Python console, and support for the Alembic file format.
A number of structural changes have been made to make it easier to manage the huge datasets that photogrammetry can generate, especially when scanning the environment.
The new experimental Volume of Interest (VOI) system works like a three-dimensional version of the rendering area system, allowing you to set a cut-off volume within which data is displayed.
Parts of meshes or point clouds outside the volume are not displayed in the viewport, which in turn improves interactive performance, but the rest of the data is still present. Any filter applied when VOI is set is now applied only to the visible part of the dataset.
In addition to the above, project files are now organized in a modular fashion: point clouds, meshes, and textured meshes are now loaded on demand, resulting in “dramatically” shorter load and save times.
3DF Scarlet is a new, standalone version of laser scan data logging software, with “unblocked” rendering, designed to improve interactivity within the software.
Users have the option of pre-processing the data set to reduce its density, including setting points outside a predefined range or setting a maximum value for the number of points in the scan.
Other changes include a new Python console to complement the existing batch processing tool, designed to allow users to automate a wider range of repetitive tasks.
The 3DF Zephyr 6.0 update also extended the tracking marker detection system; markers in the image can now be highlighted and the software automatically detects the centre of the marker. The system also works with spherical markers used in forensic medical reconstructions.
3DF Zephyr 6.0 is available for 64 bit Windows 8 and above. The software is CUDA based and therefore requires an Nvidia video card to use it with GPU acceleration.
The free version of the software includes a basic set of tools, works with 50 source images or video frames and only runs on one GPU. The Lite version costs $169, supports up to 500 source images and two GPUs.
The full version supports unlimited source images and multiple GPUs, as well as advanced features including 3DF Scarlet. A perpetual licence costs $4,600 and a subscription costs $290 per month.
