matlab - Set colormap on scatter3 plot -


i plotting depth image (rgbd) scatter graph, using scatter3(x,y,z) in matlab.

how can set colormap on scatter3 plot color dependent on z-value?

thanks

do want 3d-visuasation?

then use scatter3 follows:

scatter3(x,y,z,[],z)

where [] can number specifying size of circles, otherwise default 36 used.

if want use z definition color, use simple scatter

scatter(x,y,[],z)

you can set colormap usual:

colormap(hot)

example:

[x,y,z] = sphere(16); x = [0.5*x(:); 0.75*x(:); x(:)]; y = [0.5*y(:); 0.75*y(:); y(:)]; z = [0.5*z(:); 0.75*z(:); z(:)];  scatter3(x,y,z,[],z) colormap(hot)

enter image description here
