趁著週六的夜晚空檔,突然來臨的精神,希望救回 drake.csie.org 的心,總算,搞定一切了…
週五,這台機器突然又掛了,趕緊寫了一封「求救信」給網管,網管也很阿莎力地幫我處理好了。機器雖然回來了,卻更顯得不安,一來不知道問題出在哪,二來網管也沒有寫信說明一下狀況(可能被我這類的信給弄得很煩了@@;),加上 MySQL 說有一堆 table 有問題,於是決定先行把 apache 和 mysql 都關了,一切等烤肉結束後再說。
花了好幾個小時,搞定好了 apache2, php5 -> php4, mysql 5.0 -> mysql 4.1, virtual host settings(一口氣重新處理這所有的細節,並且假設自己過去的了解都是有問題的,再一一上網 google 或是翻閱各個套件的官方文件,釐清了一些觀念,總算處理好這些軟體安裝的事了)。然後透過 drupal 的 customized theming 的威力,把 read more 給抬上檯面,Drake’s blog 改成 daily,大功告成!!
希望,這次別再有問題了,我的心臟快承受不住了。

進入太極影音工作後,認識兩位非常愛看電影的同事,而且還是待在 RD 的前輩。有次和其中之一的 Kein 聊天時,Kein 說他很愛看電影,而且會把看過的電影記在小簿子上,那種像行事曆的小本子。結果有人問他:「那你去年(2004)一整年看了多少部電影呀?」你猜他回答多少,有 100 多部…
我聽了就覺得很有趣,也想了解一下一年看很多部電影,而且還一部一部把名字和時間記下來的情況是怎樣的,加上那時每天下班都閒閒的,也不怎麼想玩 game,單自一個人生活在台北也挺閒的。於是就這樣開始了…

Wonderful to hear from you. I spent a most enjoyable 12 days in Taipei last summer. I taught a 5 day class of RenderMan at DCI. Thank you for telling me about the kind words of one of my (best) students. Very encouraging.
The “RenderMan Companion” by Upstall has 3 chapters (maybe 4) devoted to shader writing. Although it is an old book, it is still very good. “Advanced RenderMan” by Apodaca and Gritz is very good although sadly it was written before the raytracing extensions were added to prman.

Dear Prof. Kesson,
I noticed your website and your work on renderman in reading the following article by one of you students.
http://forums.cgsociety.org/showpost.php?p=2855078&postcount=99
and then I found, wow, what a great website about renderman programming and that Cutter Text Editor. and soon, I downloaded Cutter and started to think about using it for mel programming (I am not yet familiar with renderman programming) instead of gVim although I have also retrieved a full complete function list from maya doc server and made it as syntax file for vim because Cutter seems more attractive and I was very interested in that CommandPort feature.

SHADERS
Clearly, shaders play a crucial creative role in defining the appearance of a CG production. RenderMan has been adopted by many leading studios because it allows special purpose shaders to be added to those that already exist.
Individual shaders are small sub-routines (functions) written in a specialised programming language called the Pixar Shading Language. The language enables new shaders to extend the creative possibilities of the renderer; it allows computer artists to find endless ways of controlling the appearance of a 3D scene through the use of custom shaders.

最近慢慢體會到,原來 Maya 的 bug 是很多的,多到一種難以相像的地步,再加上最近 Linux 要換 file center,電腦有一台沒一台可以用的,偷了點空閒,卻得為幾天之後的進步報告傷腦筋了 ><~
題外話,現在 Maya 改叫 Autodesk Maya 了,我常常會忘記而叫它 Alias Maya ^^;

從 vgod 那看到的高橋流簡報法,好像重點就是每一頁的 slide 都只有幾個字,而且要非常的大,大到快把整個螢幕都佔據掉的樣子,而且不使用圖片,感覺挺新鮮的。接著連到簡報之道:高橋流二三事,又看到相當活躍在 open source 和 perl 圈的 gugod 學弟了,他實在太可愛也太有趣了,老是有新鮮的東西。
心動不如馬上行動,本週二的 RD meeting 時,我就小小試了一下,每一頁都只有大大的幾個字,然後再針對這個做說明,然後因為有圖有真相,還是插入了一張只有圖的 slide。不過說實在的,我並沒有好好想好怎麼呈現這次的 presentation,所以沒有把聽眾的注意力都拉到那大大的幾個字上頭去,另一方面,公司二樓的會議室的 notebook 擺的位置很差,導致 speaker 和布幕是不同方向,不同易讓聽的人集中注意在一個方向上。
話雖如此,有機會我一定要好好想想怎麼有效利用這種有趣的 presentation method。
