The file containing information of the scene is defined as the interface between the modeling application and rendering application . the interface gives two types of saving template , providing a discriminating standard for the rendering of plane models and nurbs models that coexist in the rendering application 該系統(tǒng)以存儲(chǔ)模型信息的文件作為模型建立程序和場(chǎng)景著色程序之間的接口,在接口文件中,定義了兩種類型的存儲(chǔ)模板,即用多邊形集描述平面模型,用nurbs描述曲面模型。
Proved by the model data , the studied method can be applied to study the feasibility of time - lapse seismic . the software for model establishment not only can be applied for complex model with a good precision , but also can change the velocity in the special formation with a gradient 時(shí)移地震速度模型建立程序不僅能建立復(fù)雜的速度模型,而且精度要高,并且根據(jù)研究的需要,速度在任意層能在橫向上和縱向上按規(guī)定梯度變化,這是常規(guī)地震勘探速度模型建立程序所不能辦到的。
