title: PRo3D Releases
# Getting Started
To get started please download your preferred version of PRo3D below. PRo3D supports importing `*.obj` files, but you can also download one of our example datasets in `opc` format:
* <a href="http://download.vrvis.at/acquisition/32987e2792e0/PRo3D/GardenCity.zip">Garden City</a><sup></sup> (single reconstruction
* <a href="http://download.vrvis.at/acquisition/32987e2792e0/PRo3D/VictoriaCrater.zip">Victoria Crater</a><sup></sup> (multiple reconstructions)
Unpack the PRo3DViewer.zip and start PRo3D.Viewer.exe. For instructions on how to import data and use PRo3D please have a look at our tutorials at [pro3d.space/GettingStarted](https://www.pro3d.space/#started). PRo3D is also available in source code form on <a target="_blank" rel="noopener noreferrer" href="https://github.com/vrvis/pro3d/">Github</a>.

## PRo3D Viewer 3.1.2 - 21.12.2020
Download PRo3D Viewer 3.1.2 **... in final testing**
* removed tooltips from icons as they were irritating for many users (will be switchable in the next release)
* we added the 'JPL' coordinate system, which is the same as the 'None' system but with an inverted z-axis.
* potential fix for the ominous 'unreferenced ressource' crash
## PRo3D Viewer 3.1.0 - 25.11.2020
We are proud to announce the first official open source version of PRo3D built on the .net core runtime.
Download PRo3D Viewer 3.1.0 [Windows](http://download.vrvis.at/acquisition/32987e2792e0/PRo3D/20201125_PRo3DViewer_3_1_0.zip)
Find source code on [GitHub](https://github.com/vrvis/pro3d)
At the moment we only support Windows platforms, but we are working on also providing releases for linux and mac.
# Technology & System Requirements
PRo3D is based on the functional-first libraries of the [The Aardvark Platform](https://aardvarkians.com/), available on [github](https://github.com/aardvark-platform). In December, we will finish the final bits for mac os finally making the application fully cross-platform.
CPU: Intel i5 or AMD equivalent
GPU: dedicated GPU, NVIDIA Geforce 700s Series or greater
RAM: 8 GB
CPU: Intel i7 or AMD equivalent
GPU: NVIDIA Geforce 1650GTX or AMD equivalent
OS/Runtime: Windows 10 (64bit, v10.0.17763), .NET Core 3.1 (linux and mac versions are in development)
Graphics: NVIDIA Kepler Architecture (GTX 6*) or greater
PRo3D's performance may vary with the size and type of datasets and the selected quality settings for surface rendering. PRo3D may as well run on machines beneath the required specification. Most of the time, PRo3D also runs on AMD cards, but it is not guaranteed.
