OpenCities Planner Update, April 2022

New versions of iModels, TerraForm improvements, new Draw tools, Start screen updates, Unit Per Pixel, updated Showroom

Interesting new things have been released since our previous Update, and here are all the highlights!

Choose which iModel to upload into

With this new workflow, you can make new versions of an iModel.  The iModel you have selected will become the default one for the next upload you do.

This enables updating your iModels without the need to reconfigure them whenever you wish to add more data to them.

Draw Tools

With our new Draw tools you can now draw Polygon and Line features in the Editor. Quick sketching and annotation are enabled, providing a simplified workflow for simple vector additions to your project.

Terraform Improvements

​These latest improvements in our TerraForm tool provide better rendering of the control points of the TerraForm shape. You can also easily modify nodes after creating them, by clicking the line to add a new one or choose ALT + Click to remove one.

This offers better control to the user and it reduces the need to re-draw a polygon from scratch when editing.

Start Screen updates

​We are now using a better compression  and a better responsive scaling for the image tiles. These have improved the quality of the images uploaded on a project’s Starting Screen, offering a proper rendering of the images making them look good on all resolutions.

ShowRoom Updates

We have been developing a new version of the ShowRoom application, which will support iModels and be consistent with the online version of OpenCities at all times.

It supports local map datasets, but project content such as POIs, uploaded 3D-models and iModels, and GIS-services such as WMS will require an active internet connection. As reality models and background data typically hold the most heavy content for a project, the ShowRoom application will offer increased performance over the online version for exhibitions and situations where the internet access is unstable. It also features a brand new user-friendly GUI.

An Alpha version has been released to pilot users for review and feedback.

Unit per pixels for Reality Models

Introducing you the Unit Per Pixel (UPP) feature, an advanced visualization setting that allows you to control what data is being rendered. The Unit Per Pixel setting offers a better control of Reality model rendering where the default Unit Per Pixel calculation is non-optimal.

This new Unit Per Pixel is aimed to be used for advanced  situations if there is need to tweak your mesh model to either look better or load faster.
