Real estate presentation and sales touch screen app for Dunapart

Our client decided that they wanted to start showcasing and presenting their pending properties to prospective clients earlier than the official handover, thus speeding up the sales process.

The Duna Terrace was not our first real estate project, but we encountered several challenges. These included the high graphic presentation we were aiming for, the accurate

use of materials, the large and varied vegetation expected, and the specific people and vehicles to be represented. In addition, this not only had to be run on a PC with a very powerful HW in 4K resolution with a touchscreen, but also on an iPad Pro. Fortunately, we were able to negotiate with our client to get the PC configuration we suggested, so we ended up with a then powerful Nvidia Geforce RTX 2080 Super equipped with an Intel i7 processor, 32GB RAM and SSD storage.

By properly optimizing the model of the huge building complex (from ~120M pilogons to ~36M polygons), carefully selecting the right models and plants, and applying practices in the visualization (multi-level LOD phases, UI elements included in Atlas, GPU instance materials, occlusion culling, real-time light calculation and reflections), we finally achieved optimal visualization and runtime performance. In the end, this project became our best-looking residential real estate sales support software. However, the same was problematic to achieve in an iPad Pro still equipped with the A12 chip. Fortunately for us, right around the same time, devices with the M1 chip came out, giving us a huge boost in resources. Of course, there were also tricks to be done here, such as selective activation of individual objects, Dynamic Quality settings, burnt highlights and further polygon reduction. Another big challenge was the connection to the existing occupancy system, which was already running through a ready-made service called MiniCRM. The settings of this had to be slightly modified to get the JSON format we needed. After lengthy discussions, this was resolved, so that we could finally see the actual occupancy data and housing information in the application.

The beauty of the project was also a challenge. It was a joy to see the whole project begin to take its final shape thanks to the implementations that were made, and to see it in progress as it came to life even more with each subtask that was completed.

The first days after the handover were not entirely without events. It turned out that the printing function was not working properly due to the internal network, and users also experienced a strange flickering, not to mention the fact that the iPad only displayed the elements in monochrome. In the end, we were able to resolve these issues very quickly after the initial setup, thanks in part to on-site monitoring and in part due to remote desktop access.

The software was finally up and running in our client's office well before the complex was built, and thanks to the online booking system, positive feedback was constantly monitored.

In the end, almost all the properties were sold very quickly.
