Hi Rafa, Could the tile identifier not be encoded into the filename string? This is how I'd tackle it.
If you really need a fully custom paging mechanism then why not just implement your own. Robert. On 5/31/06, Rafa Gaitan <[EMAIL PROTECTED]> wrote:
Well, our own tiles.. are an extension of PagedLOD (TilePagedLOD), they incorporates a tile identification inside... The idea is make all system dynamic, to support variable layers and in general support GIS datasets. I know that PagedLOD.. and DatabasePager is not made to support this architecture, and we are extending functionality to do it. By now the system creates tiles on demand .. and requestTexture and HeightFields to a data acces layer. The problem is the continuous increment of memory, and we want to use (or extend) the databasePager to unload those tiles less used. If is necessary create those tiles again..it's ok.. we create and request data again. We have a disk cache of texture and HF tiles, so it's quickly to reload it. Any suggestion about the implementation of the DatabasePager? Thanks. Rafa.

How would reference tiles without a filename to indentify it? BTW the filename is just a string, you can actually encode anything you want into this string and use a Pseudo loader to decode this string into a tile reference.
