shading (MATLAB Function Reference)

Set color shading properties

shading flat
shading faceted
shading interp

Description

The shading function controls the color shading of Surface and Patch graphics objects.

shading flat

each mesh line segment and face has a constant color determined by the color value at the end point of the segment or the corner of the face that has the smallest index or indices.

shading faceted

flat shading with superimposed black mesh lines. This is the default shading mode.

shading interp

varies the color in each line segment and face by interpolating the colormap index or true color value across the line or face.

Examples

Compare a flat, faceted, and interpolated-shaded sphere:

subplot(3,1,1)
sphere(16)
axis square
shading flat
title('Flat Shading')

subplot(3,1,2)
sphere(16)
axis square
shading faceted
title('Faceted Shading')

subplot(3,1,3)
sphere(16)
axis square
shading interp
title('Interpolated Shading')

Algorithm

shading sets the EdgeColor and FaceColor properties of all Surface and Patch graphics objects in the current Axes. shading sets the appropriate values, depending on whether the Surface or Patch objects represent meshes or solid surfaces.
