Stereoscopic Vision to Human Beings

Our human perceptual systems have been driving changes in our entertainment media, one sensor at a time.

Since we are built to see motion, pictures naturally evolved into motion pictures. Motion pictures evolved to incorporate sound, color, 3D sound, and 3D vision. We use all of these, all day long. There's no reason we would want to give any of them up when we watch a movie. 

When sound first came out, a lot of people complained that it was a gimmick. "So, what're you gonna do, have every movie be a musical now?" They didn't think about the emotional impact of hearing just regular dialogue's nuances, nor of a full soundtrack. They were so used to working another way that it never occurred to them to ask, what becomes possible now that wasn't possible before? 

That's where we are with 3D. It has been treated like a gimmick, but we are starting to think about how it can be used as a creative tool. 

讓網頁變成 3D (紅/青）

從 gugod 的OSDC / RubyConf TW 2010 複習得知了 3D Bookmarklet 這玩意兒，趕緊拿自己的網站來試試：

程式碼裏頭，有關 anaglyph 的部分如下：

e.style.color='rgba(255,0,0,0.5)'+imp; 
e.style.textShadow=d+'px 0 0 rgba(0,255,192,0.5)'+imp;

如果能採用 Half Color Anaglyph 或是 Optimized Anaglyph 公式的話，然後是對整個畫面處理（包含 img, css 裏的 background image/color, color）等處理，那就更完美了 :)

Convert Filip's Wedding Photos into 3-D

The interesting is, we, as artists and engineers, do really can convert 2D images into autostereoscopic ones, as long as having skilled rotoscoper with patience and cooperative computer graphics geek. What we did is just as normal as everyone could thought of:

• define our targeting quality and appearance first and clearly
• pick up candidate wedding photos with remarks of importance and focus points
• for each photo, circle out spatial layout according to aesthetics and logistics. furthermore, having well-designed depth gradient is the most important to achieve nice quality result
• rotoscoping, the most time-consuming but artistic process
• 3d image warping, or so called depth image based rendering is used to generate the desired multiple novel views
• finally, (auto)stereoscopic device related content generating

Does a pure computer graphics researcher need to know and even involve in those stuff to this extreme? Yes! Because...

• there are seldom "pure" researchers for this field though~
• your research result needs some proof, which requires other talent's help.

I love to cooperate with other talents :)

3D Business

3D business is not born yet. It is like an expected new born baby. I say new technology regarding 3D is necessary for 3D business. It is said "Necessity is a mother of invention".

3D technology is a sort of a "Mother of 3D business". Then who is a "Father" of expected new born baby named "3D business"?

It is "Business model" who would become a "Father".

Only when "Technology" meets "Business model", new business will be born.

All of the 3D related people need to collaborate to establish 3D business. "Competition to Collaboration" is my message.
