MATLAB 3D函数fill3()

fill3函数可创建平面阴影和Gouraud阴影多边形。

句法

fill3(X, Y, Z, C) // It fills three-dimensional polygon. X, Y, and Z triplets specify a polygon vertices. If X, Y, or Z is a matrix, fill3 develop n polygons, where n is a number of columns in the matrix. fill3 close the polygons by linking the last vertex to the first when necessary.
C specifies color, where C is the vector or matrix of indices into the current colormap. If C is the row vector, length(C) must same size(X, 2) and size(Y, 2); if C is the column vector, length(C) must same size(X, 1) and size(Y, 1).
fill3(X, Y, Z, ColorSpec) // It fills three-dimensional polygons defined by X, Y, and Z with color specified by ColorSpec.
fill3(X1, Y1, Z1, C1, X2, Y2, Z2, C2, ...) // It specifies multiple filled three-dimensional areas.
fill3(..., 'PropertyName', PropertyValue) // It allows us to set values for specific patch properties.
h = fill3(...) // It returns a vector of handles to patch graphics objects, one handle per patch.
