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”。 / }nrF4S UR Oj9CO v 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： X_D6eYF Normal Vector ^DBD63 N" The Normal Vector is a vector in 3D space that is used to orient the projection \Y*!f|=of plane for the irradiance map. The plane is defined to be perpendicular to the "@.Z#d|Y Normal Vector, and the irradiance incident on the selected surface is projected `$J'UXtGc onto this plane. When the map is displayed, the normal vector is pointing toward It%T7
X# you. 0/ut:RV0 Up Vector l <:`~\ # The Up Vector is a vector in 3D space that is used to orient the projection plane }% eDEM for the irradiance map. The plane is defined so that the Up Vector is parallel to the @. " q vertical side of the plane. The irradiance incident on the selected surface is ~6p5H}'H1 projected onto this plane. When the map is displayed, the up vector will point GGCqtA^@7d toward the top of the screen.
