如果你想一下自己寫要怎樣寫這個程序，就很容易理解這個程序了。
一直從下向上畫圓，然后把下面的圓擦掉，就能得到一個向上升的煙花效果，
爆炸效果就是先畫小圓再畫大圓，然后擦掉小圓，再擦掉大圓。

喔哇，
都是啥子年代了，
還食古不化，
在觸摸屏幕用手指劃動而產(chǎn)生燃放煙花的虛擬圖像效果，
早就被時代徹底底拋棄了！！
現(xiàn)在都是在空中一劃，根據(jù)手勢，根據(jù)手勢的空間運動，
立即就是實際來真格的，
真實、震撼、空間大爆炸、場面駭人、驚天動地。
無接觸，
摒棄虛擬的虛假玩意兒。
你吹一口氣，
燃放裝置就噴出一股火焰。
機械加工能力和基礎(chǔ)強勁的，
產(chǎn)生1米邊長見方立體焰火造型，
與產(chǎn)生100米見方焰火造型的設(shè)備是通用的。
你與情侶自拍“刷臉”就立即產(chǎn)生肖像燃放造型，
其詳細的工程技術(shù)細節(jié)，
早就有中英文對照的文本，
照著去做就可以了，
無需操作機床加工的人員，
去“進一步研究思考”、去開展“創(chuàng)造性的工作”。
就是找了三個隨機數(shù), r,g,b作為顏色的初始色彩,在三個數(shù)字上偏移, 得到相近的顏色.. 并畫出來..
