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 :)

立體內容的製作，讓人頭痛之一的事就屬算圖了

這是一張使用了八個鏡頭，每個鏡頭經過算圖產生出來的結果。

不管是要帶眼鏡的雙眼立體，或是不需要帶眼鏡的裸眼立體電視，製作過程中，讓人第一時間就覺得頭很痛的，就屬算圖了。拿一般製作動畫的流程來看：Layout -> Animation -> Lighting -> (Effects) -> Rendering -> Compositing -> Editing，整個過程中，只要其中之一覺得有修改的必要，就可能往前退到任何一個部門，然後就有很高的機率要重新算圖。雙眼的話，很高的機率是重算兩眼，如果是裸眼立體的話，運氣好的話，就是 5 個 view，運氣不好的話，就是 12 個 view，這是一個很直接的負擔，不管對製作的 artists/TDs 或是運算的機器而言。

Dreamworks 透過 main cam 亦即是 left cam 的設計，來使得一些情況下，只需要重算 right cam 就行了。那如果是 8 cams 的情況呢? 我在想的是，有沒有可能犧牲掉一些 high frequency information 精確度的前提下（ex, specular, reflection, caustics, sss），然後使用內插的方式來湊出 n views 呢?
