public void LoadRawTextureData (byte[] data);
public void LoadRawTextureData (IntPtr data, int size);


data テクスチャのピクセルを初期化するのに使う byte 配列
size データのサイズ(単位はバイト)。


Raw 形式データを読み取ってテクスチャのピクセルを格納します。

この関数はテクスチャピクセルメモリに Raw データを格納します。これは、圧縮テクスチャ形式データをテクスチャに読み込むには最も有用です。

Passed data should be of required size to fill the whole texture according to its width, height, data format and mipmapCount. Otherwise a UnityException is thrown.

Mipmaps are laid out in memory starting from largest, with smaller mip level data immediately following.

For example, a 16x8 texture of RGBA32 format with no mipmaps can be filled with a 512-byte array (16x8x4).

実際にグラフィックスカードによって変更されたピクセルをアップロードして Apply を呼び出します。
