向量vectors设置问题，不清楚如何设置Normal and Up Vectors，你可以在Irradiance/Illuminance Options中选中"Automatically calculate Normal and Up Vectors”。 lsCD%P SouPk/-B80 另外，分析图的颜色和项目也可以在Irradiance/Illuminance Options中设置。
站长说的很对，补充一下： 3TVp
oB` Normal Vector @]P# ]%^D2 The Normal Vector is a vector in 3D space that is used to orient the projection p \A ^kX^5 plane for the irradiance map. The plane is defined to be perpendicular to the qgg/_H:;w Normal Vector, and the irradiance incident on the selected surface is projected nAPSs]D onto this plane. When the map is displayed, the normal vector is pointing toward 4+e 9:r ] you. k FE2Vv4. Up Vector z )s{>^D The Up Vector is a vector in 3D space that is used to orient the projection plane [y-0w.V=oE for the irradiance map. The plane is defined so that the Up Vector is parallel to the S&_Z,mT./ vertical side of the plane. The irradiance incident on the selected surface is GjN/8>/ projected onto this plane. When the map is displayed, the up vector will point *yKw@@d+p toward the top of the screen.
