[筆記]PS3與Wii比較 影片的省思

應該是玩家自製的廣告 SONY過分重視技術 忘了game play遊戲的本質. 雖然這是在諷刺PS3 但是在3D動畫產業 所有的動畫師都該知道: 不要過度執著於新的技術 新的外掛 內容才是最重要的!

[教學][影片] NURBS建模教學套餐 tutors set

建模是我最弱的一環 尤其是NURBS 由於市面上3ds max書籍關於NURBS建模很少 例子也太過簡單 多流於介面說明 所以我參考其他的CAD軟體書籍 把一些工業設計常見的專題 以3ds max軟體來建立 希望嘉惠3ds max的使用者. 教學1~4不需要任何外掛. 5與6需要nPower Power NURBS外掛軟體操作. 你可以到官方網站下載試用版. 3ds max的NURBS經常令人詬病 除了太陽春之外 無法用NURBS操作boolean, 另外其fillet指令也不容易使用 原本我想用Rhino 3D來建模 但是後來發現Power NURBS的外掛就能完全取代Rhino 3D同時又能在3ds max環境下使用 值得推薦.

This video tutors demo you how to model PET bottle,advaned NURBS modeling. Please note you need npower Power NURBS plugin to make this model.

Description of this tutor:
In this video tutor I combine NURBS fuction in 3ds max and use the npower power NURBS plugin to perform some task during modeling this PET bottle. I take advange of the "Xcurve" function in power NURBS to make the wave pattern of this bottle. For the bottom of this bottle, I use the powerbollean to cut out the shape and fillet the it.

It seems that npower power NURBS has bug, so I am stick with default NURBS in 3ds max, until some task can not be done by default NURBS.

Tips: the cut out the shape of wave pattern, better check the "cap" fuction after you revolve the cure for the middle part of the bottle.

Material setup:

[筆記]弄懂材質--合成材質篇(composite)

3ds max當中有很多種材質與貼圖都與合成有關 名子也很像 容易混淆 這裡特別做比較說明:


1~3是材質material 4~6是貼圖map. 材質與貼圖的差異 前篇以介紹過了. 這六種材質/貼圖都與影像合成有關 如果弄懂了 應該對材質觀念有幫助.

首先是2與4非常像 compositor與composite 兩者都是合成的意思 不同的是一為貼圖 另一為材質. 解釋2的意義: 其base material就是底層材質的意思 其上的材質Mat1, Mat2...可以依序疊加. 這裡的Mat2等 一定要加上透明度(mask)這樣base的材質才會顯現 否則覆蓋過後只剩下mat2等疊加的材質能夠被看到. 合成的方式有a (addictive), s (substrative), m (mix)三種 這裡a的方式是最直觀的. 簡單的說就是 composite材質即為底層材質 然後疊加新的材質上去 (玩過photoshop的圖層就很容易理解).

材質的合成能夠建立像是 塑膠+玻璃等混合物體 然而貼圖的合成辦不到.

而4是compositor真的和2很像. 差別在於4適合成貼圖 而其map2的貼圖必須要有alpha等透明度設定(tif檔) 否則map2會把map1所覆蓋.

1blend材質 這裡mat1相當於base material 而mat2覆蓋上去, 由mask控制mat2的覆蓋程度 換句話說mask是加諸在map2之上的 如果mask當中是黑色 則材質顯露出mat1的樣子 而mask是白色 則顯示mat2的樣子.

與belnd很類似的是shellac材質 差別在於 shellac的材質base與shellac材質之間有上下之間的關係 而blend材質的mat1 與mat2是混合而已 沒有上下的關係.

5mask 這個貼圖通常不會單獨使用 (通常會與composie material搭配) 這裡map1 相當於之前介紹的map2貼圖 而mask是加諸於map1之上的 那你會問mask的base材質為何? 就是diffuse color而已. mask適合做為一物體上面貼貼紙的作業上.

6mix, 這個又和blend幾乎一模一樣了 差別就是一個為材質 一個為貼圖而已.


舉例:


想像一下你有三張投影片 一張印有綠樹 一張是紅蠟燭 一張是人群(黑色代表透明) 這裡你把綠樹放在底下(base) 疊上一張紅蠟燭 然後再用人群去遮蓋紅蠟燭 就會得到圖像3

如果改遮蓋程度為50% 就會得到圖像4

3ds max材質最難理解的就是合成 影像合成的概念也不過是如此.

[連結]3分鐘學會使用3ds max內建的全局照明

[筆記]弄懂材質--反射折射篇 reflect/refract material and map

想要徹底弄懂材質 於是打算做一系列的比較 藉由比較各種材質貼圖 徹底了解其參數的意義與限制. 在3ds max當中要建立反射 折射(reflect and refract)的材質 有很多種方法 這裡介紹至少有3種方式 7種結果. 可以用raytrance material與map來解決: 問題是到底什麼是材質(material) 與貼圖(map)呢?

我個人的理解是 材質如塑膠 金屬 玻璃等都算是材質. 在3ds max當中如果物體給予了玻璃材質 那個物體整體就是玻璃的材質. 而相對的貼圖而言 貼圖是一張圖片貼在物體表面 呈現出物體的樣子.

一個材質可能包含多種貼圖 但是一個貼圖就只能是某個材質 因為貼圖是材質的子集合. 簡單的說 貼圖是貼在材質之上的. 你可以用不同的材質建立不同性質的質感 例如混合塑膠與玻璃材質 但是你沒辦法混合塑膠與玻璃貼圖 建立兩種質感 因為貼圖就是貼圖 無法同時表現兩種質感.

想像一個圓柱體 你可以給予玻璃材質 那圓柱體看起來就會像是玻璃; 如果你不給予玻璃材質 而是利用像機去拍攝真的玻璃 然後把玻璃的影像印刷出來 把印刷的照片貼在那個圓柱體上 如此一來 乍看之下 那個貼有玻璃相片的圓柱體 看起來也像是玻璃了.

這就是貼圖與材質最大的差別. 簡單的說 貼圖可以算是一種取巧的方式. 跟玻璃材質比較 玻璃貼圖的方式是比較有效率多了 但是其結果卻是不夠真實.

再舉一個例子 室內裝潢有錢人就會用實心木板 沒錢的就用三合版. 三合版是用木屑擠壓成行的版子 外層可以貼圖(map) 看你是要花梨木 就貼花梨木的貼圖 要柚木就貼柚木的貼圖. 而實心木板就是直接用花梨木 或是柚木的木料. 三合板比實心木便宜許多 如果說三合板就是貼圖(map) 而實心木就是材質(material) 那也是很貼切 因為三合板比實心木便宜 而map也比material運算的快的多.

這裡比較三種方式建立反射/折射的效果
1. 用raytrance material 將reflect改為全白 這樣物體就會呈現反射

2. 用raytrance material 放置在refelct map 這樣物體就會呈現反射

3. 用reflect/refract map 放置在refelct map 這樣物體就會呈現反射

4. 用raytrance material 將transparency改為全白 這樣物體就會呈現折射(透明)

5. 用raytrance material 放置在refract map 這樣物體就會呈現折射(透明)

6. 用reflect/refract map 放置在refract map 這樣物體就會呈現折射(透明)

7. 最後一種方式 但是只能用在平面上 就是用flat mirror放置於refelct map

8. 補充: 若是要折射的話 還可以用thin wall reflection


比較一下這些不同方式 可以看出raytrance material的效果是最好的 而用map方式呈現的反射或折射 結果會太白

比較一下三種方式的介面:


可以發現複雜度 是raytrance material>raytrance map>refelct/refract map

簡單說明一下: raytrance material有很多選項. 而raytrance map也不見得就比raytrance material差, 因為raytrance map具有attenuation的選項. 看看reflect/refrcat map介面相當簡單, 它的原理就是建立一個cubic map貼在物體的六面 產生折射與反射的錯覺 這裡size:100 就是指貼圖的解析度. 如果你不想即時建立cubic貼圖 可以事先建立六面貼圖, 軟體會運算所指定的物體 產生六張解析度為100*100的貼圖供你使用.
