就是我的模型光線追跡出現(xiàn)很多這樣的錯誤 ydNcbF%K

有網友說是兩個物體相交面重疊的問題，那么應該怎么處理呢，是不是將一個表明刪除。 w/KCuW<  
謝謝

你沒有辦法刪除一個表面，如果你不是指表面屬性的話 d1c_F~h<  
我的辦法是復制其中一個然后讓他們相減構造一個緊貼的表面，這樣比直接靠在一起出現(xiàn)錯誤光線的機會小很多 t(4%l4i;X  
其實我的意見還是，少量出現(xiàn)這樣的光線不影響最后結果

Coincident Surfaces C:n55BE9  
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: ^ ~HV`s  
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). eu(1bAfS&T  
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. T!uK_  
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: l>RW&C&T  
抱歉公式打不出來 &p1Et  
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. Y`QJcC(3  
Note that other surface properties, such as the BSDF (BRDF or BTDF) are foundin an analogous method.

謝謝，只是有錯看起來不舒服，呵呵

樓主是不是在模擬LED芯片結構，我也遇到同樣的問題，不知道怎么解決～
