課程目標
在學TD之前
覺得很難非常正常,練久過瓶頸期就順了,上課時會放慢讓大家跟著一起操作
TD 特點
- 快速建構 Shader 與視覺藝術
- 即時音像表演(結合 Live 或其他 DAW)
- 做為橋樑串接不同軟體
- 互動遊戲
- 處理多重訊號(不同維度採樣取樣)
- 即時濾鏡
- 使用場景:演唱會/博物館/互動裝置/表演/ 3D光雕/ 風扇投影

入門的過程
- 很痛苦 迷惘感很重
- 完全不確定每個元件在做什麼
- 了解快速鍵跟基礎介面
- 看過大概的元件類型跟數據流 做出簡易的影響混成
- 跟著簡易的教學實作點東西
- 跟著複雜但是詳細的教學實作一樣的作品
- 試著自己動一些參數
- 理解怎麼看元件的demo
- 跟著教學實作10個以上的作品
- 開始做自己的小作品
- 開始連結外部硬體 midi 鍵盤
- 開始看大型專案理解架構邏輯
這週課程教學目標
- 理解元件與介面
- null 當整線器,避免刪節點時亂跳
- add 圖片相加
- composite 合成操作(包含加減乘除…等)
- level 亮度、銳利等操作
- 搜尋 In 可找到各種 Input (課堂有 movie)
- 熟悉快速鍵與操作
- 滑鼠左鍵移動,滑鼠右鍵可以範圍選擇
- 滑鼠中鍵可以看圖片大小
- P 屬性
- D 展示當前節點到背景
- A 進入並操作該節點 (要在按一次 A 或 ESC 退出才會變一般操作模式)
- Ctrl/cmd + A 全選
- tap or 滑鼠點兩下 新增節點
- 數值調整可以用按住滑鼠中鍵上下左右移動快速調整
- 靜態影音/即時視訊輸入
- 能靜態合成影像
- 能操控數據流 (CHOP 裡)
- absTime.seconds 可以當作變數放在數值格子裡
- constant 可以用來紀錄數值
- 按 A 進入 Active 模式,點開其他節點,用滑鼠拖移置要關聯的項目
- 要關掉 Active 可以點節點右下角的星號
- math mapping/數值加減乘除/整數…等
- selct 過濾 chanel
- 能通過數據改變元件的參數
- 能透過畫面上的控制項操控數據
- Blur 模糊
- Level / HSV 改變顏色
- Lookup 顏色對應
- Displace 扭曲
- Feedback 回饋使用法
- 能輸出靜態影像跟影片檔案
- 錄製時要勾掉 realtime 才能錄製完整的影像,而非電腦給的 Frame 數
