Terrain(r) importer
mikemahoney218 opened this issue · 4 comments
First step for unifir: automatically import terrain tiles created via terrainr. The ideal UI is still an open question for me -- should the user even know tiles are being made? should there be a function that takes a single elevation raster and makes it in Unity? -- as is how to get there; this issue is to collect scraps I find while looking around for ideas.

}"Taking terrainr tiles into Unity" feels like an odd thing to live in this package, instead of terrainr
But I think if anything that's an argument to move raster_from_raw_tiles out of terrainr -- make that a tight API client package with a few spatial utilities, move the Unity stuff into its own package, pass single merged images between the two to interface
