Surface Texturing
显示 更早的评论
I want to create a square surface with circular dimples on it. Circular dimples are like cylinders in which depth, radius, distance from one dimple to another should be variables. Like a chess board but instead of squares in want circles and instead of 2D i want 3D and I want to control the distance between each cylinders. Can anyone please help me out on this

This is not as difficult as you think. You can use the following code as a starting point. Once you understand why it works, then modify it to fit your needs.
xmin = -100;
xmax = 100;
[X,Y] = meshgrid(xmin:xmax);
ctrs = linspace(xmin,xmax,5);
M = ones(size(X));
for Xctr = ctrs(2:end-1)
for Yctr = ctrs(2:end-1)
R2 = (X-Xctr).^2 + (Y-Yctr).^2;
M = M - (R2 <= 20^2);
end
end
h = surf(M);
zlim([-40 40])
set(h,'facecolor','none');
axis vis3d
zoom(3)
