PV3D with DAE 模型動畫應用

好久都沒有發一些關於 FLEX 的東西了，不過檢視後台的訪客資訊，程式設計與平面設計的訪客比率大概是 60 比 40 ，前一陣子剛好與 阿默設計 一起合作，寫了一個教學用到個 3D 互動程式，因為我只有負責寫使用 PV3D 的互動區的部分，因此我也不太知道這個東西用在哪裡囉。另外感謝好友 壞蛋 的建模，他也是一位熱心的網友在玩 PV3D 與 FLEX 喔，是一位研究所的研究生呢。

因為這次的東西用到太多因此我就不多做解釋了。各位看官請自便，先看看執行結果吧 ?

showExample[1]

這個範例你可以看到 :

  1. PV3D 如何崁入 FLEX 內
  2. DAE 如何載入 PV3D 與 FLEX 內
  3. 多邊形的建立方式
  4. DAE 的模型動畫載入 PV3D 與 FLEX 內
  5. 3D 物件的半透明化

差不多是這樣子，文章我就不再多說明了，有放了一些註解在裡面，因為有很多測試碼，所以寫得不是很好，如果有看的朋友可以詢問一下，如果有問題可以再詢問 ^^ ， 原始檔我打包在下面，需要的朋友可以下載回去。

    這是用DAEMC做的!!!
    好嗨喔!!!
    什麼時候要講解一下DAEMC呢??
    還有另一個問題
    就是當我使用camera.moveBackward(10)
    模形小的時候感覺不出來
    可是當我使用大模型時
    他真的像是一格一格慢慢前進
    不是很順，請問有什麼辦法可以讓它真的像是拿著攝影機
    前後左右的流覽呢(表達有點不清楚)

    你好~
    我有兩個問題,請教一下
    1.請問在你的檔案 Inactive4Cone.as 裡有下列這行:
    import org.papervision3d.objects.special.DAEMC;

    這是在那一個PV3D的版本？
    我找了最近很多版本都沒有 DAEMC 。

    2.這個的主要用途？

    謝謝^^

    @樂
    因為效能不彰的關係吧….
    線條太多的時候移動起來真的會很頓

    @Woods
    1. DAEMC 他是一個將 DAE 模型載入後可以像 movieClip 一樣可以播放
    是一個非官方元件 你搜尋 DAEMC 就可以找到下載點

    2. 主要用途第一點說完了 ^_^

    您好，最近才摸索flex，看到您這個功能很有趣，載來看一下，可是在CameraControl.as頁面中，會出現錯誤，錯誤的描述是：找不到定義 org.papervision3d，其它行數也有出現找不到定義的問題，請問該怎麼解決呢?還是我在載入檔案過程中有錯誤?我還很菜，如果問的問題很笨，請包涵> <”

    @Maybe
    那是因為你要先加入path阿
    要先去下載PV3D的SWC
    建議你先看看其他篇有關PV3D的文章
