How to change the color of model obtained from pcfitsphere

Hello everyone,

I am beginner to Matlab and would like some suggestion on how to change the colour of the model (obtained form [model,inlierIndices,outlierIndices] = pcfitsphere(ptCloudIn,maxDistance)) as it is making the analysis of the point cloud and the sphere extremely difficult.

Thanks in advance

load('object3d.mat');

figure
pcshow(ptCloud)
xlabel('X(m)')
ylabel('Y(m)')
zlabel('Z(m)')
title('Original Point Cloud')

maxDistance = 0.01;

roi = [-inf,0.5,0.2,0.4,0.1,inf];
sampleIndices = findPointsInROI(ptCloud,roi);


[model,inlierIndices] = pcfitsphere(ptCloud,maxDistance,...
            'SampleIndices',sampleIndices);
globe = select(ptCloud,inlierIndices);


hold on
plot(model)

Now if you want to change the color of figure and axis just wirte

i am setting it to white, you can chose your color

set(gcf,'Color','w')
set(gca,'Color','w')

Thanks. But I want to make the color of the sphere uniform from a multi-coloured sphere.

[Mehmed Saad]

obj_1 = findobj(gca,'type','Surface')

obj_1 =

Surface with properties:

EdgeColor: [0 0 0]

LineStyle: '-'

FaceColor: 'flat'

FaceLighting: 'flat'

FaceAlpha: 1

XData: [31×31 single]

YData: [31×31 single]

ZData: [31×31 single]

CData: [31×31 single]

Show all properties

You can change its properties.

set(findobj(gca,'type','Surface'),'FaceColor','y')
