Question

2. Write a Matlab program for bitmapped images and display any image on the surface of object in two ways b) In figure 2 the expected result is shown any image taken should rotate on sphere surface in 3 Dimensions File Edit View InsertTools Desktop Window Help Figure 2

Answer 1

clc
% read image
[I,map] = imread('kids.tif');
% rotate the image, as image gets autorotated in warp operation
% following command rotates the image 180 degrees, i.e. upside down
I = imrotate(I,180,'bilinear','loose');
% create dimensions for the surface
[X,Z] = meshgrid(-100:100,-80:80);
% create the surface equation
Y = Z.^2 + X.^2;
% figure 1
figure
% create the image on the surface
warp(X,Y,Z,I,map);
% second surface
[X1,Z1] = meshgrid(1:0.5:10,1:20);
Y1 = sin(X1)*3;
% figure 2
figure
warp(X1,Y1,Z1,I,map);
