PhotoMesh can generate a flat surface with correct texturing over a user-defined water body. PhotoMesh automatically reconstructs any above-water elements – boats, piers, small islands without requiring special user markings. The water body is defined by drawing or importing a polygon and then setting the water body’s altitude. Water bodies can be either of the following:
- Leveled – A constant water level (i.e., altitude) is set for all points in the water body polygon, to create level water bodies such as seas, lakes, ponds, and pools. This is especially useful for creating a level water body on top of a non-flat terrain or mesh, or for creating a flat water body based on an imported polygon with variable altitude values.
- Non-Leveled (Sloped) – PhotoMesh segments the water body polygon into multiple flat reconstruction tiles, each of which has a different elevation value based on the average elevation within the specific tile. This option should be selected to create an elevation gradient for water bodies such as rivers, with non-uniform water levels.
All new polygons you manually create are saved into a “Manually Created” layer that is saved under the Water Bodies group in the Project Tree. If you open a legacy project with water polygons, the water polygons are converted to the new feature layer format during the load. The project must then be saved to save the changes.
