    --- title: 陳易昇 tags: AI --- :::success 活動大共筆:https://hackmd.io/@ejc/2023gaiconf ::: [TOC] # 陳易昇 ## NVIDIA Omniverse 如何串連工作流加速 AI 創作 ### 前言(什麼是 Omniverse ?) [投影片](https://drive.google.com/file/d/1Agb0CDyaa2L4qyvnfYxQ7wHip591B9Ft/view?usp=share_link) - 幫助、增加協作 (以往都必須用「接力」的方式完成) - 傳輸 sync 檔案很方便 - 有各種不同的軟體、格式,Omniverse 可以把大家連結在一起 - 各個平台之間的平台 - 使用者包含(designer、engineer、PM) - 每個 party 能透過 USD(新的檔案格式) 連接到 Omniverse Nucleus(讓大家可以sync檔案的server) - [NVIDIA Omniverse](https://www.nvidia.com/zh-tw/omniverse/) ### speciality of NV Omniverse - open standard (.usd) and open-source - by Pixar - Simulation Tech 擬真科技 - physics simulation - even large instance can be simulated - MODULUS, AI powered physics simulation - AI - Specialized Arch - Omniverse workspace can be access through VR headset - 可以串連的平台 - Unreal、Ps、blender.... - 雙向支援的軟體,可以直接接到平台上,使用者對檔案格式無感 - 單向支援的軟體 - 讓檔案轉成 USB 格式,透過編譯轉譯器轉意 - NV PhysX 多種模擬 機械動作、洪水、熱流 Modulus - 西門子離岸風力發電 - 原本做物理模擬需要高達好幾個月 - 透過擺設優化,讓效率達到為大 - 計算風機設計 - 40 day -> 15 min - 透過低解析度的優化,達到同樣模擬效果 - 風流 優化 可視化 將發電效能最大化 - 10 % lower cost ### NVDIA OmniVERSE For 3D Design Collaboration - Integrate AR and VR(equals to XR) - 家用級 NV 產品也能 access Omniverse - use VR to adjust design-加速創作 - e.g. 帶著 VR眼鏡到場景內調整室內設計的擺設位置(體感使用者觀看螢幕的高度之類的) - AI Audio2face (AI-Enabled Facial Animation) - Machinima (Simple 3d game cinematics) - Create (Simple 3d game cinematics) - View (Review & Approvals) Demo footage: Audio to face Audio to gesture Omniverse USD Composer(formerly Case) RTX renderer 渲染器 可拓展 看到真實虛擬世界,跟個節點做連結 Omniverse FARM 讓 Content 做==離線式渲染==,用 ==150== 個GPU 在 18 天內算完 未來企業就不用到外面找算圖農場處理了 > Video Footage [NV Omniverse Farm 如何創造元宇宙版本老黃](https://www.youtube.com/watch?v=f_V30ueEXE4) Omniverse XR - 用==光追==做虛擬世界協作 - 不是什麼醜醜的元宇宙或虛擬世界(兇) 有個人和企業版本,一年 9000元美元管理費 omniverse for individuals is free 大公司切出 GPU算力,跟別人做協作 就算只是平板也能調用 GPU 算力 減少浪費、成本節省,時間做出好作品,加速到 Production ### Usecase M&E Media & Entertainment - 預演 - 協作效果 各種人在工作空間工作 協作:藝術家、導演都能做協作,最後呈現給client RTX On:打光到滿意,再做最後輸出 透過鏡頭偵測動作,再對應到3D人物 用平板掌鏡,發現打光不對,從現實調整,都是即時串在一起發生 M&E例子: - 傳統軟體做預演,不支援 TD? - 傳統軟體看起來不夠真實 - 用 Omniverse 可以讓導演看到最接近真實狀況渲染 - 用 full fidelity 有光追效果 虛擬世界在每個行業都看得到,經由AI 模擬動作或聲音模擬,都能加速業界前進動作 聲音模擬 ### NVIDIA AI Foundation partnered with Google cloud, MS azure and Adobe <!-- 有 Adobe 嗎我記不清了 --> 為了去面對:Stable Diffusion and CGPT's disruption - contact center support - Ai video - Graphics and Video AI Foundation (google、Azure) - NeMo 架構 LLM 雲端Service,將前端需求和最後輸出串接到雲端 客服問答系統 跟 AI NeMo對接,快速產出,不用管機房問題,也有做這樣 Service,加速中小企業競爭上需求 加速競爭建置需求 - Picasso 面對的是 AI 影像影片生成,或 3D模型 ex.Runway,如何建置自己的? 可以不用再買 A100 或 H100 ~~因為缺貨,你也買不到😂~~ 建置自己模型,優化他,跟自己的資料庫對接 - Bionemo 製藥、疫苗有關,藥品和疫苗無法偵測蛋白質組成 一次研發就是十多年,經由模型 Service,把蛋白質在藥的反應模擬出來 加速藥品研發 client: 輝瑞 透過 DGS 趕上業界需求 跟上業界需求 ## 總結 - Omniverse 提供即時協作,幫助創作者專心於創作上 aodio space 經由租用服務,和技術服務,可以搭建生成影片、片模型,甚至製藥都可以選用這些 Service ## Q&A [QA截圖](https://hackmd.io/_uploads/Hyv3zYE4h.png) - 請問omniverse 跟生成式AI的關係? - GenAI 幫助 concept 發想,但還是需要 production - 所以 GenAI 是協助工作前期,但現階段接力後的工作流依舊沒有加速,需要有 Omniverse 跟 GenAI 接力 - 講者您好,我們一直都知道 3D 設計軟體對硬體的需求是比較高的,請問 Omniverse 對硬體的需求高嗎?未來有沒有可能降低硬體這方面的門檻嗎?(雖然知道這跟 NVDIA 的 Business 好像有衝突 😂 - 假設你的工作流比較小,3060 就可以跑 Omniverse 了 - 軟體之間協作,以前只能開一個 unreal,但如果要同時開好幾個 3D 相關軟體,就需要 Omniverse。 - 取決於 workflow 所需的 workload,決定需要多少硬體資源 - 在雲端運算後,串流到電腦裡,減少硬體需求。 - 請問什麼時候要抽顯卡(來亂不要當真🤪) - 沒回答QQ (微笑+發呆) - 請問speech to actions 是訓練的,還是用生成式AI產出的? - 語音輸入的環境 - - 是否有在 NV 內部導入 GPT 加速內部流程? - 目前沒有導入 GPT,但因為自己有 Tool,語言模型和生成式 AI,都已經有很多技術在用 - 翻譯:~~我們有很多自己開發的 GenAI Tool,所以不用別人開發的~~ - 翻譯:~~chatGPT 沒我家的 tool 牛~~ - 3D 工作流透過 - NVIDIA 股價?(不用回答) ## 參考 - 說會有投影片 - [AI Foundations 是 NVIDIA 為企業準備的自訂生成式 AI、大型語言模型雲端服務](https://chinese.engadget.com/nvidia-ai-foundations-customizable-genewrative-ai-cloud-service-060059293.html) - [NVIDIA 企業級生成式 AI](https://www.nvidia.com/zh-tw/ai-data-science/generative-ai/) - <!-- Nvidia, YES! -->
