    就是我的模型光线追迹出现很多这样的错误 \I[50eh|

    有网友说是两个物体相交面重叠的问题,那么应该怎么处理呢,是不是将一个表明删除。 G,fh/E+  
    谢谢

    你没有办法删除一个表面,如果你不是指表面属性的话 yNU.<d 5  
    我的办法是复制其中一个然后让他们相减构造一个紧贴的表面,这样比直接靠在一起出现错误光线的机会小很多 }XcYIo#+t  
    其实我的意见还是,少量出现这样的光线不影响最后结果

    Coincident Surfaces 6#gS`X23Y  
    TracePro models often incorporate geometry with coincident surfaces. Thisoccurs for such systems where two objects have one common side, e.g., acemented doublet. This section describes the behavior of TracePro with respectto Surface Properties applied to those coincident surfaces. The tree cases are: i&_&4  
    1.No Surface Property (i.e., <None>) applied to either coincident surface - TracePro will calculate the reflectance and transmittance at this interface based on the Index of Refraction specified in the Material Properties for the two objects (the Fresnel reflection and transmission coefficients). INjr$'*  
    2.Surface Property applied to one coincident surface only while the other surface has the Surface Propery of <None> - TracePro will use the parameters of the single defined surface property to determine the flux and direction of the resulting rays. 2uZ4$_  
    3.Surface Properties applied to both coincident surfaces - Although this condition is somewhat nonsensical and is not recommended, TracePro will combine the two surface properties in accordance with the equations below: |S0nR<x-M  
    抱歉公式打不出来 4#"_E:;PQ  
    where R1, T1, and A1 are the reflectance, transmittance, and absorptance,respectively, of the first coincident surface; R2, T2, and A2 are the reflectance,transmittance, and absorptance, respectively, of the second coincident surface;and Rc, Tc, and Ac are the reflectance, transmittance, and absorptance,respectively, of the resulting combined property. L5j%4BlK/  
    Note that other surface properties, such as the BSDF (BRDF or BTDF) are foundin an analogous method.
