I ' d like you to build a trace program , 我想讓你寫(xiě)一個(gè)追蹤程序
We then specify where the observer s eye will be located . the ray tracing program will mathematically model the objects , the light rays and the observer and compute the colour for each pixel on the screen 光線追蹤的程式會(huì)利用數(shù)學(xué)模型模擬物件光線及觀察者之間的關(guān)系,從而計(jì)算觀察者在電腦屏幕上應(yīng)看到的影像。
Light sources are then set up at assigned locations . we then specify where the observer s eye will be located . the ray tracing program will mathematically model the objects , the light rays and the observer and compute the colour for each pixel on the screen 光線追蹤的程式會(huì)利用數(shù)學(xué)模型模擬物件、光線及觀察者之間的關(guān)系,從而計(jì)算觀察者在電腦屏幕上應(yīng)看到的影像。
With the three - dimensional ray - tracing program , the simulation of leo - gps occultation is given . the radio path of occultation observation is simulated , and then the excess phase delay is calculated . this work can be used for studying the effects of the neutral atmosphere and ionosphere on the occultation observations and evaluating the performance of the inversion techniques 本文介紹了無(wú)線電掩星技術(shù)的發(fā)展?fàn)顩r和基本原理,圍繞無(wú)線電掩星技術(shù)及其應(yīng)用研究展開(kāi)諸多研究和探討,主要工作內(nèi)容如下: 1 、利用全球三維射線追蹤程序,開(kāi)展leo - gps掩星觀測(cè)的模擬研究,以計(jì)算掩星觀測(cè)時(shí)電波傳播路徑、計(jì)算大氣引起的附加相位時(shí)延等。
By means of the software of pro / e we studied the movement of the bit and obtained some data reports about different parameter bit . in the environment of visual basic the trace program can compute the well - bottom outline . it also can draw the trace and the velocity curve that the teeth scrape the well bottom 分析方法是在pro / e中對(duì)試驗(yàn)鉆頭進(jìn)行運(yùn)動(dòng)模擬,得到不同結(jié)構(gòu)參數(shù)和傳動(dòng)比的鉆頭運(yùn)動(dòng)的數(shù)據(jù)文件,然后進(jìn)入用visualbasic高級(jí)語(yǔ)言編制的異形牙輪單牙輪鉆頭分析軟件中,計(jì)算出鉆頭的井底輪廓曲線,并繪制鉆頭井底軌跡和牙齒刮切井底的速度曲線。
