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”。 @Sd:]h:f- . T>}O0L" 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： Q1[s{, Normal Vector OK}"|:hrd The Normal Vector is a vector in 3D space that is used to orient the projection &3J#"9 _S plane for the irradiance map. The plane is defined to be perpendicular to the 'a*IZ b-M Normal Vector, and the irradiance incident on the selected surface is projected !Esiq<Yh onto this plane. When the map is displayed, the normal vector is pointing toward |i8dI )b you. 6vA 5;a@ Up Vector ,;18: The Up Vector is a vector in 3D space that is used to orient the projection plane jwox?] f+ for the irradiance map. The plane is defined so that the Up Vector is parallel to the W'$~ m K\ vertical side of the plane. The irradiance incident on the selected surface is L]}|{< 3\ projected onto this plane. When the map is displayed, the up vector will point 9@B+$~:}7 toward the top of the screen.
