IHTApark. Multi-detailed 3D architectural model for sound perception research in Virtual Reality

IHTApark – Multi-detailed 3D architecture model

This dataset describes visual and acoustic 3D architectural models of the park next to the IHTA.

Institute of Hearing Technology and Acoustics (IHTA), RWTH Aachen, 52056 Aachen, Germany

Files are stored in FBX format for geometry, JPEG format for visual textures, and Unreal Engine for the virtual reality scenes.

VERSION 1: Visual photogrammetry + Acoustic model

Data is available separately for each definition, and for each visual and acoustic cue. The level of detail for each definition is shown here:

• Visual cues
  • Geometries
    • HighLOD
• Acoustic cues
  • Geometries
    • HighLOD

This version of the model includes only the modules used for the description of the referenced paper. The authors reserve the right to complete other levels of detail if future applications require them.

An additional data file contains a unique file in [IHTApark_UnrealEngine] Unreal Engine format, with the set up scenario. The instructions to open the final scenario are described here:

1. Download the [IHTApark_UnrealEgine] file, and save it in your working space.
2. Extract the content of the [IHTApark_UnrealEngine]. The folder naming and arrangement are prepared for the scenario.
3. Run the .uproject file.
4. Open a Content Browser tab to navigate through the folder hierarchy. You can open the Content Browser under the tabs Window > Content Browser
5. Open the IHTApark map under the folder Content > Maps by double clicking on it.
6. The scenario will be visible in the Viewport 1 tab. Go to Window > Viewports > Viewport 1 to open the tab.
7. Press key G to hide or unhide the helpers and editor actors.
8. Press keys 0, 1, 2, 3… 9 to jump into different saved view positions.
9. Drag the mouse while pressing right click to rotate the viewer direction
10. While pressing right click, press key W to navigate through the scenario.

VERSION 2: Object-based visualization in three different weather conditions
