MATLAB: How to paint a surface according to another scalar function

3d plotscolorMATLABsurface

Dear experts,

Assume I am given with the surface: z=4-x-y^2 . I now want every point on the surface to be colored according to a function: R(x,y,z).

Is there any simple way to make such a coloring?

Thanks a lot in advance!

Something like this?

[x,y] = meshgrid(linspace(-2,2,50));
z = 4-x-y.^2;
c = x.^2 - y;
surf(x,y,z,c)

Try this:

x1=@(x) 6+sqrt(2-(x-1.5)^2);
x2=@(x) 6-sqrt(2-(x-1.5)^2);
hold on
v1 = fplot(x1, [0 15]);
v2 = fplot(x2,[0 15]);
fill([v1.XData v2.XData], [v1.YData v2.YData], 'g', 'EdgeColor','g')    % Fill The Circle
axis equal
axis equal off
hold off

producing:

Note that fplot is not the best option for this, so ther is a small gap.

I’m not certain what you want to do, but one option is the alpha function, or setting the Alpha property if you want them transparent. The other option is to colour the ‘uncoloured’ faces white = [1 1 1].
