Blenderの歴史

1988年、Ton RoosendaalはオランダのアニメーションスタジオNeoGeoを共同設立しました。NeoGeoはすぐにオランダで最大の3Dアニメーションスタジオになり、ヨーロッパでも有数のアニメーションハウスの1つになりました。NeoGeoは、多国籍エレクトロニクス企業であるフィリップスのような大企業クライアント向けに、受賞作品(European Corporate Video Awards 1993、1995) を作成しました。NeoGeoでTonは、アートディレクションと社内ソフトウェア開発の両方を担当していました。慎重に検討した結果、Tonは、NeoGeo用の現在の社内3Dツールセットは古すぎて保守が面倒であり、一から書き直す必要があると判断しました。1995年にこの書き直しが始まり、Blenderとして知られる3Dソフトウェアが生まれました。NeoGeoがBlenderの改良と改善を続けるにつれ、Tonは、BlenderがNeoGeo以外の他のアーティストのツールとして使用できるようにすることを考えるようになりました。

1998年、Blenderをさらに売り込み、開発するために、TonはNeoGeoのスピンオフとしてNot a Number (NaN) と呼ばれる新しい会社を設立することを決めました。NaNの中核は、フリーで、コンパクトなクロスプラットフォーム3Dアプリケーションを作成して配布したいという願望でした。当時、ほとんどの商用3Dアプリケーションは数千ドルもするので、これは革新的なコンセプトでした。NaNは、プロレベルの3Dモデリング・アニメーションツールを、コンピューティングを使う一般の人々に届けることを望んでいました。NaNのビジネスモデルには、Blenderを中心とした商用製品とサービスを提供することが含まれていました。1999年、NaNはBlenderをより広く宣伝するために、SIGGRAPHカンファレンスに初めて参加しました。Blenderの最初のSIGGRAPHコンベンションは大成功で、マスコミと出席者の両方からたいへん関心を集めました。Blenderはヒットし、その大きな可能性が確認されました!

2000年初めのSIGGRAPHカンファレンスの成功により、NaNはベンチャーキャピタリストから450万ユーロの資金を確保しました。この大量資金の入手により、NaNは事業を急速に拡大することができました。すぐにNaNは、世界中に、Blenderの改善と促進を行う50人もの従業員を誇っていました。2000年夏に、Blender2.0がリリースされました。Blenderのこのバージョンでは、3Dアプリケーションにゲームエンジンの統合を追加しました。2000年末までに、NaNのWebサイトに登録されたユーザー数は250,000人を超えました。

残念ながら、NaNの野心と機会は、当時の会社の能力と市場の現実とマッチしていませんでした。この過剰な拡張により、2001年4月に新しい投資家の資金とより小さな会社でNaNは再開させることになりました。6か月後、NaNの最初の商用ソフトウェア製品Blender Publisherが発売されました。この製品は、インタラクティブなWebベースの3Dメディアの新興市場を対象としていました。売上げは期待外れとなり、厳しい経済情勢が進み、新しい投資家はすべてのNaN事業を閉鎖することを決定しました。シャットダウンには、Blenderの開発中止も含まれていました。複雑な内部ソフトウェアアーキテクチャ、未完成の機能、標準ではない方法で提供されるGUIなど、当時のバージョンのBlenderには明らかな欠点がありましたが、過去にBlender Publisherを購入したユーザーコミュニティと顧客からの熱心なサポートがあり、TonはBlenderを無意味にフェードインさせることができませんでした。十分な数の開発者チームを持った会社を再開することはできなかったため、Ton Roosendaalは2002年3月に非営利組織Blender Foundationを設立しました。

Blender Foundationの主なゴールは、コミュニティベースのオープンソースプロジェクトとしてBlenderの開発とプロモーションを継続する方法を見つけることでした。2002年7月、Tonは、Blenderをオープンソースとしてリリースしようとする独自のBlender Foundation計画を、NaN投資家に同意させることができました。「Free Blender」キャンペーンは、FundationがNaN投資家からBlenderのソースコードと知的財産権を購入し、その後、Blenderをオープンソースコミュニティにリリースできるように、100,000ユーロを調達しようとしました。数人の元NaN従業員を含む、熱心なボランティアグループとともに、「Free Blender」への募金キャンペーンが開始されました。誰もが驚いたことに、キャンペーンはたった7週間で100,000ユーロの目標を達成しました。2002年10月13日(日)、Blenderは GNU GPL の条件の下で世界にリリースされた。Blenderの開発は今日も続いており、Blenderの最初の作成者であるTon Roosendaalが率いる世界中からの献身的なボランティアチームによって推進されています。
