A mesh is geometry that can be rotated, lit, textured, and explored. This stage transforms SRTM grids into OBJ meshes with UV-mapped satellite textures &mdash; ready for import into Blender or any 3D application.</p> <h2 id="mesh-products">Mesh Products</h2> <table> <thead> <tr> <th>Name</th> <th>Extent</th> <th>Resolution</th> <th>Vertices</th> <th>Texture</th> </tr> </thead> <tbody> <tr> <td><strong>Peak</strong></td> <td>Parbati Parbat ±10 km</td> <td>step=3 (~90 m)</td> <td>~400K</td> <td>2048² Sentinel-2</td> </tr> <tr> <td><strong>Valley</strong></td> <td>Bhuntar to Pin Parvati</td> <td>step=4 (~120 m)</td> <td>~300K</td> <td>4096×2048 Sentinel-2</td> </tr> <tr> <td><strong>Expanded</strong></td> <td>Full GHNP + Khirganga NP</td> <td>step=6 (~180 m)</td> <td>~416K</td> <td>Bare (vertex colour)</td> </tr> <tr> <td><strong>Kullu</strong></td> <td>Full Beas drainage</td> <td>step=8 (~240 m)</td> <td>~316K</td> <td>Bare (vertex colour)</td> </tr> </tbody> </table> <h2 id="output-format">Output Format</h2> <p>Each mesh produces three files:</p>
