| MAXON_METHOD Result <void> Init | ( | Int | tileSize | ) |
Initializes the tile-based change tracking data structure. Each tile contains an AABB. The number of tiles is determined as numTiles = ceil(imageWidth / tileSize) * ceil(imageHeight / tileSize). We recommend reasonable power-of-two values such as 64, 128, 256, 512 or 1024.
| [in] | tileSize | The size of a tile in pixels. |
| MAXON_METHOD Result <void> GetAndResetDirtyState | ( | DirtyState & | dirtyState | ) |
Returns and resets the accumulated region changes in form of a set of non-overlapping tiles.
| [out] | dirtyState | The state to overwrite. |
