頂点配列用にvector.emplace_back(1,1,1,1);などと言った二次元配列を作る方法が知りたい。

Question

メッシュ用の配列としてvector二次元配列を用意して１頂点ごとに設定したいのですがどうすればいいのでしょうか？一様知っている範囲で調べながら型を設定しましたがemplace_back(1,1,1,1,1,1);と入力できません。とりえず固定配列にしました。

	std::vector<std::vector<float>> vec;//メッシュ

bool Game::Initialization(HDC dc)
{
    //デバイスコンテキストを作成
    mDeviceContext = dc;



	//メッシュ
    int mesh[][8] =   {
		{-0.5,-0.5,-0.5,0,0,-1,0,0},
		{0.5,-0.5,-0.5,0,0,-1,1,0},
		{-0.5,0.5,-0.5,0,0,-1,0,-1},
		{0.5,0.5,-0.5,0,0,-1,1,-1},
		{-0.5,0.5,0.5,0,1,0,0,-1},
		{0.5,0.5,0.5,0,1,0,1,-1},
		{-0.5,-0.5,0.5,0,0,1,0,0},
		{0.5,-0.5,0.5,0,0,1,1,0},
		{-0.5,0.5,-0.5,0,0,-1,0,-1},
		{0.5,-0.5,-0.5,0,0,-1,1,0},
		{-0.5,0.5,-0.5,0,1,0,0,-1},
		{0.5,0.5,-0.5,0,1,0,1,-1},
		{-0.5,0.5,0.5,0,1,0,0,-1},
		{-0.5,0.5,0.5,0,0,1,0,-1},
		{0.5,0.5,0.5,0,0,1,1,-1},
		{-0.5,-0.5,0.5,0,0,1,0,0},
		{-0.5,-0.5,0.5,0,-1,0,0,0},
		{0.5,-0.5,0.5,0,-1,0,1,0},
		{-0.5,-0.5,-0.5,0,-1,0,0,0},
		{0.5,-0.5,-0.5,0,-1,0,1,0},
		{0.5,-0.5,-0.5,1,0,0,1,0},
		{0.5,-0.5,0.5,1,0,0,1,0},
		{0.5,0.5,-0.5,1,0,0,1,-1},
		{0.5,0.5,0.5,1,0,0,1,-1},
		{-0.5,-0.5,0.5,-1,0,0,0,0},
		{-0.5,-0.5,-0.5,-1,0,0,0,0},
		{-0.5,0.5,0.5,-1,0,0,0,-1},
		{-0.5,0.5,-0.5,-1,0,0,0,-1}
	  };
    
	//インデックス
	int idx[][3] = {  
		{2,1,0},
		{3,9,8},
		{4,11,10},
		{5,11,12},
		{6,14,13},
		{7,14,15},
		{18,17,16},
		{19,17,18},
		{22,21,20},
		{23,21,22},
		{26,25,24},
		{27,25,26}
	};



    return true;
}

自己解決です。

std::vector< std::vector<int> > v (0, std::vector<int>(4) );
