Hi, i want to plot a rgb image in 3D dimension. Z axes is for the color data. Currently, i have something like this
but i don't want the z-line to be plotted, ijust want to see how the surface looks. Maybe something like this
How can i make it? Thanks a lot. Here is my code for now:
img= imread([imdir,filename]);
if size(img,3)>1
img = rgb2gray(img);
end
[x,y]= meshgrid(1:size(img,2),1:size(img,1));
z = double(img);
min_x = min(min(x));
min_y = min(min(y));
max_x = max(max(x));
max_y = max(max(y));
figure; hold on;
surface(x,y,z,'edgecolor','none');
imgzposition = -100;
surf([min_x max_x],[min_y max_y],repmat(imgzposition, [2 2]),...
img,'facecolor','texture','edgecolor','none')
view(45,30);
xlabel('x');
ylabel('y');
zlabel('z');
