OpenHealth的工作坊特邀曾任教於 MIT Media Lab（Context Aware Computing Group），現任教於卡內基美隆大學的教授Ted Selker，以探索健康生活為主題，歡迎對互動設計與智慧運算有興趣學子們，與大師共同激盪出有趣、有創意的健康生活新方案。 ...

Siggraph 2008 的一篇論文：[Upright Orientation of Man-Made Objects](https://www.cs.ubc.ca/nest/imager/tr/2008/upright_orientation/ )。這篇論文的目的是要把 3D 模型給擺正。只要你隨意給一個 3D 模型，使用這篇論文裏的方法的話，就能把一個模型擺正到可以平放在桌面上來。（註：其實是人造的物件為主，如果你是給一隻兩隻站立的狗的話，不曉得會跑出什麼結果來~） ...

My personal viewpoints of SIGGRAPH 2011 after lots of discussion with friends, colleagues, and someone. It is very subjective and the presentation on Prezi is just a testing. The presentation is not completed yet but I think it’s enough to leave it in this way. Check the source presentation: Summary of SIGGRAPH 2011 on Prezi

More and more research papers focusing on controllable or guidable topics are proposed, like ShadowDraw , NPR Noise , Example-Based Elastic Materials , Photo-Inspired Modeling , Assembly-Based 3D Modeling . Alembic 1.0 is proposed to supersede long-running OBJ and work successfully in this industry, just like OpenEXR for images. Open source might not be the right way, but joint development is the way! Deep image compositing(1 , 2 , 3 ) is hot. Weta developed and used it for Avatar on Pixar’s Renderman and The Foundry’s Nuke is going to support that. Furthermore, deep image format is included in the standardization of OpenEXR 2.0. Katana is going to be release in this year, which is a 3D application specifically designed for the needs of look development and lighting in an asset based pipeline. The course: Stereoscopy from XY to Z is awesome and really informative. ( slides by NVIDIA , brief on real-time rendering ) Global illumination by ray tracing is the trend but volumetric rendering is the next! Shrink Wrapping, low-res and distant cars in Cars 2 are modelled by a simple cube with displacement shaders. Not a new idea but it still looks cool. When we talk about 3-D, the stereoscopic vision, people are still mentioning the min/max disparity/parallax issues, like some safe zone, the bearable disparity angles, and the min/max stuff. Even Disney puts ‘comfortable’ as the top of stereoscopic principles. But, Disney also starts to mention emotional stereo and emotional distance. Current volumetric renderers still base on ray tracer or REYES. Blue Sky thinks crowd simulation takes time, slower loading and easy to crash your memory-limited machines, it is better to just bake variety of animations and use that to synthesize plausible crowd animation. Well, that is all because Blue Sky is using proprietary ray-tracing renderer! But in some situation, it makes sense. Sparse Voxel Octree (SVO)(google code: Efficient Sparse Voxel Octrees ) is the key to LoD. CG is about cheating and we all should know that in advance.

今年的 SIGGRAPH 辦在加拿大 ，說什麼也要來一趟，見識一下所謂的「好山好水好無聊的溫哥華」，順道拜訪一下老朋友 仁瑋 賢伉儷。除了看看美侖美幻、有海景與海鷗相伴的 Vancouver Convention Centre 之外，也想感受一下溫哥華市區的生活步調。只能說，這個城市的人較台北人來得節奏快一些，但同時也來得懂得享受生活。一小塊草皮、藍天白雲與溫柔的陽光，就是一個可以讓人放鬆的大自然氛圍。（我與同事，趁著一個午休時間，拎著一個便當，走了幾個 block，跑去參加了一場 Musical Nooners 的戶外音樂會。聽聽音樂，看看小朋友在草地上奔跑，精神整個都來了~） ...

PS. Vancouver is really beautiful.

上頭是我目前打算在 SIGGRAPH 2011 的暫時（我相當懷疑，參加 SIGGRAPH 可以事先很明確地訂下行事曆來……）的行程。每天的行程看起來都還挺不錯的，至少，幾乎每晚，都會參加一個“晚會“，像是 Taipei Reunion, The Foundry GeekFest, Disney R&D Mixer, RenderMan Users Group Meeting~ 我同行的同事更帥氣，他還找到了 Houdini User Group Meeting 來著，先祝他有個很有看頭的一晚 :) ...
