DTrierFlood (Unity)

Unity 6000.3.0f1 URP project for viewing/importing DGM1 terrain tiles (supports XR via OpenXR/XRI).

Quick Start

• Open the project in Unity 6000.3.0f1 (URP project).
• Place exported data from GeoData into Assets/GeoData/: height_png16/ and tile_index.csv.
• In Unity, run Tools > Geo Tiles > Import Terrain Tiles (PNG16), keep the resolution/tile size consistent with the exporter (default 1025 and ~1000 m), and choose whether to delete existing tiles under Geo_Terrain_Tiles.
• Test in Assets/Scenes/SampleScene.unity; XR packages are present (OpenXR, XR Interaction Toolkit, Composition Layers) if you want to enter VR.

Notes

• Importer (Assets/Scripts/Editor/GeoTileImporter.cs) reads the CSV header order-independently, enforces R16/single-channel texture import settings, anchors terrain origin at the minimum xmin/ymin, and sets Terrain Y to global_min with height span (global_max - global_min); it can also apply ortho textures and optionally import buildings/trees/furniture when present.
• Generated or cache folders like Library/ and large raw datasets should stay untracked; keep generated GeoData assets stable to avoid scene churn.
