「Paperspace」を利用したVRChatの始め方

MacユーザーがOculus Questだけ買って、PaperspaceというクラウドゲーミングサービスPCVRChatを1年やってみたらかなり良かった。やり方を書き置きしておきたい。


2022年9月時点でのHow to・セットアップ方法記事がなかったので、先人のブログ引用しながら、変更点注意点などを書き残しておきます

使い始めた経緯

コロナ禍で好きな音楽現場へ行く事が難しくなり悶々としていた2021年夏頃、友人に「VRChatのVRクラブがおもろいから、騙されたと思ってOculus Quest2一緒に買って始めてほしい」と言われ、4万空中に投げたと思って、ノリだけでOculus Quest2を買う。

元々VRChat自体に憧れはあったが、家にはMacbookオフィス向けWindowsしかなかった為環境がなく、諦めていた。しか

・Paperspaceなるクラウドゲーミングサービス (つよつよグラボを積んだPCネット通して借りれる)

・Virtual Desktop(\2000) (Questと接続されてないPCを繋ぐQuestアプリ)

・Oculus Quest2(当時4万弱)

・Paperspaceを起動する端末(MacでもWindowsでもスマホでもOK

の4つが揃うだけでプレイできるらしい。価格は1$前後/1h。手元に必要ものブラウザが立ち上がるPCとQuestのみ。初期投資必要金額は4万前後

まぁちょっと旅行行ったと思って4万払ってみよう、体験版と思ってやってみるか〜 と思って始めたが、これが思いのほか快適で結局1年間使い続けてしまった。

もし「Quest版のVRChatをやってみたけど全然おもしろくなかった」「PC版でガッツリやってみたいけど家にあるPCスペックが足りない、或いはMacしかない」という人がいればぜひ参考にしてもらいたい

海外鯖の為、pingは100msほどあり軽度のラグが生じ、FPS系のゲームには向かない。

ただ、昔のSkype程度のラグのため、VRChatで会話コミュニケーションを行うにはほぼ不便を感じなかった。




やり方(準備・セットアップ


基本的方法は以下のブログ参照。

https://suna.hateblo.jp/entry/2019/06/30/015730

とりあえずP5000インスタンスを借りる承認が降りるまでは、やや時間がかかる(多分手動で承認作業をしてもらっている)のでSubmitのところまで記事に従ってやっておくが吉。

※この申請が通るまでは待ちなので、インスタンス構築手順は進められません。また、お金はこの時点ではかかりません。

[追記]上記ブログ内「3. 鍵がついているけどP5000をクリックする」の工程の画面が、2022年9月現在と大きく異なるようです。

Machine Type からP5000(鍵マーク付)を選択

→ 上記ブログの内容を参考にRequest Approvalへ申請理由を記入

→ Addを押して申請完了してください。

---

注意点

上記ブログについて、2022年9月現在では記事内8番の工程より先は大きく内容が異なる。そのため一旦無視を推奨する。

また、設定方法でも異なる部分が多くあるため、6点ほど注意点を書き残しておく。



①paperspace導入時(インスタンス構築手順)の最初の画面が現在ブログのものと大きく異なっている。

最初の画面でcore選択 → Help us~~ の画面で 利用目的を「hobbyst」「gaming」「just me」にしてcontinue を押し、マシン作成の画面に移行してください。

インスタンス構築の手順に入る前に、先にクレカ情報登録する。(P5000の申請を行うための必須作業登録のみなので支払いは発生しません)

ページ右上の■から「Billing」を選択して、「Payment Method」の項目に名前と住所(英語表記)・クレカ情報入力して、Addしてください。

③設定内容は変わらないが、選択部分の文字表記等が異なる部分がいくつかある。

ブログと同じマシン設定の場合の、項目名および選択・変更するもの表記は以下(参考にしてください)。

Machine Type P5000

OS Licensed のWindows10 

Region WEST COAST(CA1)

Desksize 100GB ※デスクサイズの変更については後述

Advanced options オン → ブログを参考にPublic IPAuto-Shutdown、 Auto-Snapshotを設定。

記事内9番の工程「VirtualDesktopインストールする」は ”Oculusから” 購入・インストールする。

SteamでもVirtualDesktop販売しているのだが、こちから買えるものは今回使う用途のものではありません。買っても無駄金になります。気をつけてください。(自分と友人らはここでしっかり詰んだ

⑤この記事11番「サイドロード版のVirtual Desktopインストールして起動する。」

この工程現在必要なし。飛ばしOK

⑥月額の課金額が変わるが、HDD容量が足りなくなるのでDesksizeは100GBに増やしておく。

※もし50GBでマシン作成してしまった後であっても"Upgrade Machine"の項目からワンクリックで増やせます



---



8番の工程まで完了したら

①OculusからVirtual Desktopアプリを購入(\2000)

※繰り返しになるが、Steamで売っているVirtual Desktopは、今回の環境時では使わない。間違って買ってしまった場合には返金をお願いしましょう。

②paperspaceのマシンに以下の順でインストール

※Virtual Desktopストリーマーを先にインストールすると不具合が出るパターンがあるようなので、なるべく最後インストールすることを推奨


これでセットアップ完了です

使用スタート


ブラウザでpaperspaceにログインクラウドPCマシンを立ち上げる

②paperspaceのマシンの起動を待っている間に、手元のOculusを起動

③OculusでVirtual Desktop起動

④Virtual DesktopからpaperSpaceのマシン接続(うまくOculusアプリインストールID連携が済んでいれば、Virtual Desktopを起動するだけで自動でつながる)

⑤Oculus左手の 三 のボタンを押して、VirtualDesktopメニューからVRモードVRChatを立ち上げる

以上でPC版のVRChatが開始できます

西海岸クラウドPCと繋いでゲームをするため、お使いの各家庭の回線環境依存する部分はあるかと思うので注意。

※ただ、iphoneのテザリングでもギリ使えたという話もあるので、相当回線速度が低くなければ意外といける可能性あり


まとめ ~MacユーザーでもゲーミングPCがなくてもVRChatが楽しめる~

上記の手順を踏めば、家にWindowsゲーミングPCがなくても、PCVRChatをVRモードで遊ぶことができる。

個人的感想だが、ことVRクラブにおいては、デスクトップモードVRモードでは体験が全く別物で、

デスクトップモードDOMMUNETwitchを見ている感覚と大差はない +マビノギとかのネトゲをやっている感覚って具合で

20%くらいしか面白くない。

ぜひ上記記事を参考にして、クラウドゲーミングPCを導入してみてください。

マジでNVIDIAGeForce NOWとかがVRChatに対応してくれたらコスパも良くてちょうど良いんだけどな・・・

外国人が働きたい国」で日本33カ国中32位についてるブコメについて

https://www.itmedia.co.jp/business/articles/1909/27/news026.html

これ。

元ネタは https://www.expatexplorer.hsbc.com/global-report/ に載ってるランキングで、日本が32位になったことについて

憤っているらしいブコメ散見されるが、それについて思ったことを記してみたい。

1.これってHSBC駐在員に聞いた偏ったランキングでしょ?

Helpによると、HSBC expat (オフショア銀行業務を担うHSBC100%子会社)がその顧客のみならず、広く海外駐在員用のSNSから

回答を募ったもの(※1)。従って、以下のようなコメント的外れと思われる。

id:moons 英国金融大手企業で自社の駐在員にどこで働きたいか聞いたんでしょ

id:fefefefe 調査対象HSBC駐在員だけ?

id:otihateten3510 なんか分析が雑じゃね? 「HSBCホールディングスが各国の駐在員に聞いた」

各国駐在員=HSBC従業員ではないだろう。外国人駐在視点という偏りはあろうが、

海外就労考える人にとってはその偏りは有益であろう。

2.駐在員はエリート外国人労働者全般には当てはまらない

回答した各駐在自身のことについて述べているのか各駐在員の分析によるものかどうかはわからないが、調査項目は

政治的経済的安定性、可処分所得所得身体的・精神健全さ、キャリア上の進歩等多岐にわたり(※2)後者可能性が高いし

エリート以外の外国人労働者にも関係する調査項目と思われる。

id:next_neet あくまで(多くは先進国出身であろう中流ホワイトカラーの)expat=駐在員を対象としたオンライン調査の結果なので

id:halpica 「各国の駐在員」というのは多分エリート

id:Shin-Fedor “「各国の駐在員が働きたい国ランキング」”だから、わりとビジネスエリートの話

3.33か国しか対象にないのはおかし

FAQによると33か国しかないのは統計処理回答者が100名以上必要で、それを満たす国を選んだとのことである(※3)。

id:electroliteベルギーエジプト韓国あたりがなく33ヵ国の選定基準は何?

(終わりに)

から働きに来ようとする人にとって、世界的に日本がその魅力度において既に高くないらしいことは事実として認めるほかない。今現在コンビニ店員に外国人が多いと感じたとしても

それが世界的に人気があるとする根拠には乏しい。でもそれが何?我々の住む日本の魅力はそんな狭い視点では語りつくせないし、嫌なことがたくさんあったとしても祖国として

住み続けようと思えるからこうして住んでいるわけで、外国人が何言おうとその点は揺るがない。それに、同じサイト日本については「ようこそ日出づる処へ」「世界的なイノベーション原動力で魅惑的な歴史伝統に満ちた多様な土地柄を備えるユニーク駐在地」とまで書かれていることも紹介しておきたい(※4)。

"Commissioned by HSBC Expat and conducted by a third party research company YouGov, 18,059 expats based in over 30 countries or territories were questioned in 2019."

Types of digital cameras

Digital cameras are made in a wide range of sizes, prices and capabilities. The majority are camera phones, operated as a mobile application through the cellphone menu. Professional photographers and many amateurs use larger, more expensive digital single-lens reflex cameras (DSLR) for their greater versatility. Between these extremes lie digital compact cameras and bridge digital cameras that "bridge" the gap between amateur and professional cameras. Specialized cameras including multispectral imaging equipment and astrographs continue to serve the scientific, military, medical and other special purposes for which digital photography was invented.

[edit]Compact digital cameras

Subcompact with lens assembly retracted

Compact cameras are designed to be tiny and portable and are particularly suitable for casual and "snapshot" uses. Hence, they are also called point-and-shoot cameras. The smallest, generally less than 20 mm thick, are described as subcompacts or "ultra-compacts" and some are nearly credit card size.[2]

Most, apart from ruggedized or water-resistant models, incorporate a retractable lens assembly allowing a thin camera to have a moderately long focal length and thus fully exploit an image sensor larger than that on a camera phone, and a mechanized lens cap to cover the lens when retracted. The retracted and capped lens is protected from keys, coins and other hard objects, thus making it a thin, pocketable package. Subcompacts commonly have one lug and a short wrist strap which aids extraction from a pocket, while thicker compacts may have two lugs for attaching a neck strap.

Compact cameras are usually designed to be easy to use, sacrificing advanced features and picture quality for compactness and simplicity; images can usually only be stored using lossy compression (JPEG). Most have a built-in flash usually of low power, sufficient for nearby subjects. Live preview is almost always used to frame the photo. Most have limited motion picture capability. Compacts often have macro capability and zoom lenses but the zoom range is usually less than for bridge and DSLR cameras. Generally a contrast-detect autofocus system, using the image data from the live preview feed of the main imager, focuses the lens.

Typically, these cameras incorporate a nearly silent leaf shutter into their lenses.

For lower cost and smaller size, these cameras typically use image sensors with a diagonal of approximately 6 mm, corresponding to a crop factor around 6. This gives them weaker low-light performance, greater depth of field, generally closer focusing ability, and smaller components than cameras using larger sensors.

Starting in 2011, some compact digital cameras can take 3D still photos. These 3D compact stereo cameras can capture 3D panoramic photos for play back on a 3D TV.[3] Some of these are rugged and waterproof, and some have GPS, compass, barometer and altimeter. [4]

[edit]Bridge cameras

Sony DSC-H2

Main article: Bridge camera

Bridge are higher-end digital cameras that physically and ergonomically resemble DSLRs and share with them some advanced features, but share with compacts the use of a fixed lens and a small sensor. Like compacts, most use live preview to frame the image. Their autofocus uses the same contrast-detect mechanism, but many bridge cameras have a manual focus mode, in some cases using a separate focus ring, for greater control. They originally "bridged" the gap between affordable point-and-shoot cameras and the then unaffordable earlier digital SLRs.

Due to the combination of big physical size but a small sensor, many of these cameras have very highly specified lenses with large zoom range and fast aperture, partially compensating for the inability to change lenses. On some, the lens qualifies as superzoom. To compensate for the lesser sensitivity of their small sensors, these cameras almost always include an image stabilization system to enable longer handheld exposures.

These cameras are sometimes marketed as and confused with digital SLR cameras since the appearance is similar. Bridge cameras lack the reflex viewing system of DSLRs, are usually fitted with fixed (non-interchangeable) lenses (although some have a lens thread to attach accessory wide-angle or telephoto converters), and can usually take movies with sound. The scene is composed by viewing either the liquid crystal display or the electronic viewfinder (EVF). Most have a longer shutter lag than a true dSLR, but they are capable of good image quality (with sufficient light) while being more compact and lighter than DSLRs. High-end models of this type have comparable resolutions to low and mid-range DSLRs. Many of these cameras can store images in a Raw image format, or processed and JPEG compressed, or both. The majority have a built-in flash similar to those found in DSLRs.

In bright sun, the quality difference between a good compact camera and a digital SLR is minimal but bridgecams are more portable, cost less and have a similar zoom ability to dSLR. Thus a Bridge camera may better suit outdoor daytime activities, except when seeking professional-quality photos.[5]

In low light conditions and/or at ISO equivalents above 800, most bridge cameras (or megazooms) lack in image quality when compared to even entry level DSLRs. However, they do have one major advantage: their much larger depth of field due to the small sensor as compared to a DSLR, allowing larger apertures with shorter exposure times.

A 3D Photo Mode was introduced in 2011, whereby the camera automatically takes a second image from a slightly different perspective and provides a standard .MPO file for stereo display. [6]

[edit]Mirrorless interchangeable-lens camera

Main article: Mirrorless interchangeable-lens camera

In late 2008, a new type of camera emerged, combining the larger sensors and interchangeable lenses of DSLRs with the live-preview viewing system of compact cameras, either through an electronic viewfinder or on the rear LCD. These are simpler and more compact than DSLRs due to the removal of the mirror box, and typically emulate the handling and ergonomics of either DSLRs or compacts. The system is used by Micro Four Thirds, borrowing components from the Four Thirds DSLR system.

[edit]Digital single lens reflex cameras

Cutaway of an Olympus E-30 DSLR

Main article: Digital single-lens reflex camera

Digital single-lens reflex cameras (DSLRs) are digital cameras based on film single-lens reflex cameras (SLRs). They take their name from their unique viewing system, in which a mirror reflects light from the lens through a separate optical viewfinder. At the moment of exposure the mirror flips out of the way, making a distinctive "clack" sound and allowing light to fall on the imager.

Since no light reaches the imager during framing, autofocus is accomplished using specialized sensors in the mirror box itself. Most 21st century DSLRs also have a "live view" mode that emulates the live preview system of compact cameras, when selected.

These cameras have much larger sensors than the other types, typically 18 mm to 36 mm on the diagonal (crop factor 2, 1.6, or 1). This gives them superior low-light performance, less depth of field at a given aperture, and a larger size.

They make use of interchangeable lenses; each major DSLR manufacturer also sells a line of lenses specifically intended to be used on their cameras. This allows the user to select a lens designed for the application at hand: wide-angle, telephoto, low-light, etc. So each lens does not require its own shutter, DSLRs use a focal-plane shutter in front of the imager, behind the mirror.

[edit]Digital rangefinders

Main article: Rangefinder camera#Digital rangefinder

A rangefinder is a user-operated optical mechanism to measure subject distance once widely used on film cameras. Most digital cameras measure subject distance automatically using electro-optical techniques, but it is not customary to say that they have a rangefinder.

[edit]Line-scan camera systems

A line-scan camera is a camera device containing a line-scan image sensor chip, and a focusing mechanism. These cameras are almost solely used in industrial settings to capture an image of a constant stream of moving material. Unlike video cameras, line-scan cameras use a single row of pixel sensors, instead of a matrix of them. Data coming from the line-scan camera has a frequency, where the camera scans a line, waits, and repeats. The data coming from the line-scan camera is commonly processed by a computer, to collect the one-dimensional line data and to create a two-dimensional image. The collected two-dimensional image data is then processed by image-processing methods for industrial purposes.

Further information: Rotating line camera

[edit]Integration

Many devices include digital cameras built into or integrated into them. For example, mobile phones often include digital cameras; those that do are known as camera phones. Other small electronic devices (especially those used for communication) such as PDAs, laptops and BlackBerry devices often contain an integral digital camera, and most 21st century camcorders can also make still pictures.

Due to the limited storage capacity and general emphasis on convenience rather than image quality, almost all these integrated or converged devices store images in the lossy but compact JPEG file format.

Mobile phones incorporating digital cameras were introduced in Japan in 2001 by J-Phone. In 2003 camera phones outsold stand-alone digital cameras, and in 2006 they outsold all film-based cameras and digital cameras combined. These camera phones reached a billion devices sold in only five years, and by 2007 more than half of the installed base of all mobile phones were camera phones. Sales of separate cameras peaked in 2008. [7]

Integrated cameras tend to be at the very lowest end of the scale of digital cameras in technical specifications, such as resolution, optical quality, and ability to use accessories. With rapid development, however, the gap between mainstream compact digital cameras and camera phones is closing, and high-end camera phones are competitive with low-end stand-alone digital cameras of the same generation.

[edit]Waterproof

A Canon WP-1 waterproof 35 mm film camera

Waterproof digital cameras are digital cameras that can make pictures underwater. Waterproof housings have long been made but they cost almost as the cameras. Many waterproof digital cameras are shockproof and resistant to low temperatures; one of them is Canon PowerShot D10, one of the first underwater digital cameras.

These cameras become very popular during the holiday season, because many people want to save the best moments from their holidays at the seaside. Waterproof watches and mobile phones were produced earlier. Most makers of digital cameras also produce waterproof ones and every year they launch at least one new model, for example Sony, Olympus, Canon, Fuji.

Healthways Mako Shark, an early waterproof camera,[8] was launched in 1958 and cost around 25 dollars. It was a huge camera and pictures were black and white.

Summer scenery to take pictures of small skills

Undesirable cameras benefits us many 100 % satisfaction, leading to numerous spectacular images, as well as the hot months is operating relating to dependable summertime. This specific classmate through break free will be able to figure out any tons in addition to waterways, downtown along with far-away beautiful gardening, and yet may these pure attractiveness to become a memento playing hit decrease, apart from skin color boil due to the high-end digicam purpose, a great deal more simple could be to evaluation whatever taking pictures competency as well as having photos. The amount, smaller try to make your work latest many of the summer season harvesting powerful see to it, typically the classmate need to next image have a go through, you become this confidently unexpected wonder.

Digital cameras would bring us lots of enjoyment, leaving a myriad of unique images, and summertime is journeying in wonderful summer season. The classmate throughout the getaway can recognize that reams together with estuaries and rivers, metropolitan and also countryside attractive panoramas, yet take place all these charm being a memento opportunity straight down, together with steam as a result of a camcorder operation, a lot more crucial is usually to examine ones own taking functionality and also taking photographs. That period, the little generate your choice have quite a few summer months firing effective be mindful, the particular classmate may as well within the next snapshot have a shot at, you will get the particular total surprising stun.

Household landscapes

By out of doors firing indoors panoramas, basic will need throughout the Windows 7, out-of-doors mild typically currently have more substantial indoors light-weight, now a couple of challenges ought to be sorted out, is the particular coverage time frame, a couple of it truly is in order to avoid a display reflective, when pics of any camera through hands-on management operate, might take number of years coverage setting up, when photographic camera goes so that you can twit style, can easily will likely be ISO level of sensitivity Surroundings bump up, this ISO 2 hundred or perhaps ISO six hundred aiming.

Inside panorama 's best golf shot employing a tripod, in any other case, wants a spot to guide, one example is in opposition to any divider and entry, and even the true reason for executing it is because very long coverage is quite effortless construct any digital camera protein shake, producing photographs regarding fluffy envision. It's best to utilize the shutter launch, or perhaps utilize to get center-weighted avoiding relocate a video camera. Notice: except if absolutely necessary, tend not to available the particular pen, stay clear of a lot more reflective.

Out-of-doors landscapes

Bring that landscape designs from the probability with the photo may well schedule some individuals or even factors, and this also may help the room inside the operation of your view photos. Get a large surfaces area photos, as an example the veranda as well as the roof top, hillside, for example. Typically inside the mid-day is without a doubt the most suitable time frame filming this landscapes. Filming, having a polarizer to adjust a illumination with the stars, produce the particular heavens develop into dreary quite a few, well known from the glowing blue stars the white kind of fog up, as a way to boost the space or room repeatedly.

Several virtually no guidebook vulnerability management of any camera together with location form, as well as the landscape designs way is completely features on the list of manner, you are able to use landscape designs way to adopt shots. Together with handbook vulnerability restrain photographic camera might opt for aperture goal option that will movie, aperture to help acquired far better pick out F8 to help you photograph or maybe F11, this photo will be extra management concentrations senses.

houses

The particular modify on the urban center is without a doubt switching, specifically together with a lot of approach large establishing intended for symbolize, and also this are at recent many portrait digital photography buffs including firing template.

Yet typical photographic camera through simply how much suitable container distortion, hence as a way to make an effort to reduce the photograph of your deformation belonging to the accumulating " up ", thus you ought to pick around substantial thoughts and opinions filming. One example is inside the steps, or perhaps some other might help the beliefs with area. If you fail to find the correct destination for a reside, you can from the again, clear of the particular lead entity to cut back a distortion. Maybe you've employed the greatest wide-angle standard zoom lens. Vivid stars will be able to replace with a developing with the darkish.

どうもありがとう、試してみる。

TCP/IP接続を有効にすればいけたのか、、制限か何かでダメだったのかと記憶してた・・・

Oracle微妙...

安定していたりマルチプラットフォームなのは良いのだろうけど

今ではMSSQLOracleっぽい排他ロック(READ COMMITTED SNAPSHOT)が出来るようになったし

ロックエスカレーションってやつで困るほどテーブルにたくさん行を作ることもなさそうだし

OracleDBを新規導入で敢えて選択したくはないな...

自分OracleDBチョイスするなら、実績や過去資産面で致し方なかったりの理由からかな。

音声、画像を簡単に取り込めるのが便利だよね。

もともと普段はAnkiっていうSRSを使ってて、

それ用にDVDを加工してくれる subs2srs ってのを去年の秋から使ってます。

単語や文章を文字レベルで覚えるのならAnkiとiAnkiで十分。Freeです。

http://www.ichi2.net/anki/

ただ、iPhone画像や音声を使ったデッキを手軽に使えるアプリがなかったので、

どうしようかと悩んでたら Anki のフォーラムで Flashcards deluxe の情報を見つけました

このsubs2srsって日本語情報がほとんどないんですけど、

DVDから字幕情報を抜いて、さらに動画エンコードやっとくと、

字幕データごとに、動画SnapShot+音声+字幕自動生成してくれる優れもの。

よく教材向けとしてとりあげられるFriends(日本語版)などをこれで加工すると、

1. (スナップショット画像)

2. (セリフ音声)

3. (英語字幕画像)

4. (日本語字幕画像)

をセットにしたTSVデータを作ってくれます。

Anki準拠のTSVファイルになるのですが、

画像や音声タグをちょっと置換するだけで Flashcards deluxe に取り込めます。
