- The following settings can be given:
None determine normals from explicit polygon vertices Automatic determine normals from overall surface properties f determine normals by applying a function f
- With NormalsFunction->f, the arguments supplied to f are as follows:
Plot3D x, y, z ParametricPlot3D x, y, z, u, v ContourPlot3D x, y, z, w RegionPlot3D x, y, z
- The function f must return a vector of the form . Only the direction of this vector matters; the vector is in effect automatically normalized to unit length.
