Show HN: TerrainSR – fast, realistic heightmap upscaling model
A new open‑source project called TerrainSR offers a rapid, realistic method for upscaling heightmaps used in 3D terrain rendering. Leveraging deep learning, the model can enlarge low‑resolution maps while preserving fine details, reducing aliasing and improving visual fidelity. The tool is available on GitHub and has attracted interest from game developers, GIS professionals, and researchers.
