Class TileMipChain
- Namespace
- LansMap.Core.TileCodecs
Mip-chain arithmetic for square tiles: level count and total texels from one shared log2, so staging, the tile array, and the memory budget agree.

Methods
ChainTexels(int)
Total texels across every level of the chain.
public static long ChainTexels(int tileSizePx)Parameters
tileSizePxintSquare tile edge in px, greater than 0.
Returns
- long
Sum of ss for each level. For a power-of-two size N this is (4N*N - 1) / 3, just under a third more than the base level.
LevelCount(int)
Levels in a full chain, floor(log2(size)) + 1.
public static int LevelCount(int tileSizePx)Parameters
tileSizePxintSquare tile edge in px, greater than 0.
Returns
- int
Level count, 1 for a 1 px tile.
