MATLAB颤动3色彩地图

Question

我有一个MATLAB的颤抖3情节与代码和情节如下，我希望行接近中心点（这是青色蓝色）颜色变化，以便我可以visulize他们距离中心的距离。任何想法我怎么能这样做？非常感谢！

hold on; 
grid on; 
scatter3(frame_cur.xyz_cam(1,:),frame_cur.xyz_cam(2,:),frame_cur.xyz_cam(3,:),'MarkerFaceColor',[0 .75 .75]); 
quiver3(frameGT_cur.xyz_cam(1,:),     ... 
     frameGT_cur.xyz_cam(2,:),     ... 
     frameGT_cur.xyz_cam(3,:),     ... 
     C(1,:)-frame_cur.xyz_cam(1,:),  ... 
     C(2,:)-frame_cur.xyz_cam(2,:),  ... 
     C(3,:)-frame_cur.xyz_cam(3,:),  ... 
     0,'b','ShowArrowHead','off');* 

Answer 1

它不使用quiver3但结果却是接近你的要求是什么。这个答案受this answer的启发。

我用surf的名称值参数'FaceColor','none','EdgeColor','interp'创建具有插色线：

% generate random 3D points 
n = 10; 
x = 2*rand(n,1)-1; 
y = 2*rand(n,1)-1; 
z = 2*rand(n,1)-1; 
% the color is the distance of each point 
c = sqrt(x.^2 + y.^2 + z.^2); 
% plot the points 
scatter3(x,y,z,40,c,'filled'); 
hold on 
% add zeros (the center point) between points 
xx = [zeros(1,numel(x));x(:)'];xx = xx(:); 
yy = [zeros(1,numel(y));y(:)'];yy = yy(:); 
zz = [zeros(1,numel(z));z(:)'];zz = zz(:); 
cc = [zeros(1,numel(c));c(:)'];cc = cc(:); 
% plot the lines 
h = surf([xx,xx],[yy,yy],[zz,zz],[cc,cc],... 
    'FaceColor','none','EdgeColor','interp','LineWidth',1); 
colorbar;
