In the last decade the processing of polygonal meshes has
emerged as an active and very productive research area. This
can basically be attributed to two developments:
Modern geometry acquisition devices, like laser scanners
and MRT, easily produce raw polygonal meshes of
ever growing complexity
Downstream applications like analysis tools (medical
imaging), computer aided manufacturing, or numerical
simulations all require high quality polygonal meshes
as input.
The need to bridge the gap between raw Triangle soup data
and high-quality polygon meshes has driven the research on
ecient data structures and algorithms that directly operate
on polygonal meshes rather than on a (most often not
feasible) intermediate CAD representation.
摘要：本系統(tǒng)以ICL8038集成塊為核心器件，制作一種函數(shù)信號發(fā)生器，制作成本較低。適合學生學習電子技術測量使用。ICL8038是一種具有多種波形輸出的精密振蕩集成電路，只需要個別的外部元件就能產生從0.001Hz~30KlHz的低失真正弦波、三角波、矩形波等脈沖信號。輸出波形的頻率和占空比還可以由電流或電阻控制。另外由于該芯片具有調制信號輸入端，所以可以用來對低頻信號進行頻率調制。關鍵詞：函數(shù)信號發(fā)生器頻率調制Abstract：The system ICL8038 integrated block as the core device，producing a kind of function signal generator，producing low cost.Suitable for students to learn the use of electronic technology measurement.ICL8038 is a kind of multi-precision oscillator waveform output integrated circuits，a separate external components only need to be able to generate from the 0.001Hz ~30KHz low-distortion sine wave，Triangle wave，square wave pulse signal，etc..Output waveform of the frequency and duty cycle can also be controlled by a currentor resistance.In addition，as the chip has a modulated signal input terminal，it can be used to low-frequency signal is frequency modulation.
