Week 15 林宜臻課堂作業

=====內插(interpolation)

動作A ------> 動作B

a=0 .................a=1

你的動作(angle[...])

angle[0] = angleOld[0]*(1-a) + angleNew[0]*a; //內插公式

口訣: 交叉相乘

ex.

a=0, angle[0] 是 angleOld[0]

a=0.1, angleOld[0]*0.9 + angleNew[0]*0.1

a=0.5, angleOld[0]*0.5 + angleNew[0]*0.5

a=0.9,

a=1, anlge[0] 是 angleNew[0]

第一節課重點: 有內插效果

第二節課重點: 複習兩週前的進度, 能用 mouse motion來改關節角度, 能存檔、讀檔, 並且和第一節課的成果結合

第三節課重點: 使用 timer 來讓讀檔/內插的動作, 可以自動播放
TODO: 請把你的期末作品要做什麼, 寫出來.....

Week 15

本周老師教的是內插
可以讓我的機器人轉來轉去
最後一節還有教到可以讓它自己撥放
就省去了用手一直按鍵盤的麻煩!!
