Javaで組み合わせ(Combination)
用意されてる言語もあるけど、これくらい書けたほうがいいよねってことでメモがてら。
組み合わせの場合は同じ要素を見なくて良いので、再帰で渡してるindexを+1してる。
第二引数に1以下を渡すとバグるけど無視でｗ
実行結果
[[a, b, c], [a, b, d], [a, c, d], [b, c, d]]
import java.util.ArrayList; import java.util.Arrays; import java.util.List; import java.util.Stack; public class Test { public static void main(String[] args) { List list = new ArrayList<String>(); list.add("a"); list.add("b"); list.add("c"); list.add("d"); List ret = combination(list, 3); System.out.println(ret); } public static List<List<String>> combination(List list, int count) { List ret = new ArrayList<List<String>>(); for (int i = 0; i < list.size(); i++) { if (i + count > list.size()) { break; } Stack stack = new Stack<String>(); stack.push(list.get(i)); _combination(ret, list, stack, i + 1, count); } return ret; } private static void _combination(List ret, List list, Stack stack, int index, int count) { for (int i = index; i < list.size(); i++) { stack.push(list.get(i)); if (stack.size() == count) { ret.add(Arrays.asList(stack.toArray())); stack.pop(); continue; } _combination(ret, list, stack, i + 1, count); stack.pop(); } } }
Microsoft Band ファーストインプレッション
MSからもフィットネス用のバンド(以下MSBand)が出たので買ってみた。
自分はJawbone UP、Fitbit Flex、Fitbit Force、FuenBand SEを今まで使っている。
MSBandは60gと他の比べるとちょっと重たい印象を持ったけど付けてる分には
あんまり違いが判らない。一回りごついのでそっちの方が気になるかも…。
防水ではないがある程度の水しぶきには対応出来てるらしい。
ちなみに付けたままシャワーは大丈夫だった。
物理キーは二つ。電源と各項目の切り替え。
メイン画面は切り替えボタンで日付、カロリー、歩数、移動距離、心拍数が切り替えられる。
個人的にすごく気に入ったのがWatch Mode。通常だとディスプレイは電源ボタンを入れないと
表示されないけど、このように時計だけ表示されて暗闇でも見える。
天気も一週間分表示可能。Phone側と同期してるみたいで、Phoneの場所の天気が表示されるっぽい。
一日使った印象だとランニングに特化した作りかな？と思った。
1km走るごとにバイブでタイムを知らせてくれる。
タイマーやストップウォッチもあるので人によっては便利かも。
Kinect v2で画像を操作する
使い方を兼ねてメモ。
左手を挙げて開いた状態から手を閉じて手前に持ってくるとズーム。
右手を挙げて開いた状態から人差し指を立てて動かすと画像スクロール。
再度手を開くと操作が止まる。
結構長いソースそのまま張り付けるけど気にしない。

Kinect v2のBodyIndexを描画する

人物以外もなんか描画されてるけど、6体認識できる人物全部同じ色で塗りつぶしてるからかもしれない。

Kinectから取得するBodyIndex用なのでサイズは固定の512x424で作ってる。
それっぽく表示されたので多分大丈夫ｗ

Direct2Dのスケルトンプログラム
ID2D1Factoryインタフェースを作ってそれから
ID2D1HwndRenderTargetインタフェースを作って描画するって流れみたい。
CreateWindow()の後にWM_PAINTが来るのでウィンドウハンドルが必要な
ID2D1HwndRenderTargetインタフェースの作成はウィンドウプロシージャの中でやってる。
本当はWinMain()の中でやりたいのだが。ウィンドウ表示するだけなのに長いｗ
