`shading` — Control flat, interpolated, or faceted surface shading with MATLAB `shading` workflows.

shading controls how surfaces and related scalar-field plots interpolate or facet their color/geometry presentation. In RunMat it is most relevant for the surface family (surf, mesh, surfc, meshc) and complements colormap-driven visualization workflows with the standard MATLAB shading flat, shading interp, and shading faceted styles.

How `shading` works in RunMat

shading flat uses flat shading across faces.
shading interp enables interpolated/smooth shading across the rendered surface.
shading faceted restores faceted surface presentation.
Shading state is subplot-local through the shared plotting metadata model.

Examples

Apply interpolated shading to a surface

[X, Y] = meshgrid(linspace(-3, 3, 50), linspace(-3, 3, 50));
Z = sin(X) .* cos(Y);
surf(X, Y, Z);
shading interp;

Compare flat and faceted shading across subplots

[X, Y] = meshgrid(linspace(-3, 3, 40), linspace(-3, 3, 40));
Z = sin(X) .* cos(Y);
subplot(1, 2, 1);
surf(X, Y, Z);
shading flat;
subplot(1, 2, 2);
surf(X, Y, Z);
shading faceted;

These functions work well alongside shading. Each page has runnable examples you can try in the browser.
