Описание методов

CreateLandPacket() публичный статический Метод

Creates a LayerData packet for compressed land data given a full simulator heightmap and an array of indices of patches to compress

public static CreateLandPacket ( float heightmap, int patches ) : LayerDataPacket
heightmap	float	A 256 * 256 array of floating point values /// specifying the height at each meter in the simulator
patches	int	Array of indexes in the 16x16 grid of patches /// for this simulator. For example if 1 and 17 are specified, patches /// x=1,y=0 and x=1,y=1 are sent
Результат	LayerDataPacket
