Matlab에서 2D avi 애니메이션 생성

Question

Matlab에서 2D AVI 애니메이션을 만들었습니다. 녹색 점 하나와 파란색 점 하나가 선을 따라 다른 방향으로 움직입니다. 하지만 이제는이 AVI 애니메이션 비디오에 다른 점을 추가하고 싶습니다.이 점은 다른 두 점과 함께 무작위로 이동하며, 여기에 코드를 작성해야합니까? 첨부 된 코드는 내 코드입니다. 도와 주셔서 대단히 감사합니다!

clc; clear; 
%time steps 

N=20; 
%start position of one moving object 

x_pos=10; 

y_pos=10; 

x1_pos=100; 

y1_pos=100; 
%speed of the moving object 

speed_x=3; 

speed_y=2; 

speed_x1=-4; 

speed_y1=-2; 
%ini white image with size 100 x 150 

image=ones(100,150,3); 
%initialization of videowriter 

outputVideo = VideoWriter('test.avi'); 

outputVideo.FrameRate = 5; %set frame rate of the image 

open(outputVideo) 
%drawing a moving object on an image plane and creating the video 

size=2; 

for i=1:N 
%update states of moving object 

x_pos=x_pos+speed_x; 

y_pos=y_pos+speed_y; 

x1_pos=x1_pos+speed_x1; 

y1_pos=y1_pos+speed_y1; 
%draw the measurement on the image using a green point with specific size size=4; 

image((x_pos-size/2):(x_pos+size/2),(y_pos-size/2):(y_pos+size/2),1)=0; 

image((x_pos-size/2):(x_pos+size/2),(y_pos-size/2):(y_pos+size/2),3)=0; 

image((x1_pos-size/2):(x1_pos+size/2),(y1_pos-size/2):(y1_pos+size/2),2)=0; 

image((x1_pos-size/2):(y1_pos+size/2),(y1_pos-size/2):(y1_pos+size/2),1)=0; 
%give the image to the video writer object 
writeVideo(outputVideo,image) 

end 

close(outputVideo);

%set the start point

%speed of the moving object 

speed_x=3;

speed_x1=-4; 

speed_y1=-2; 

%ini white image with size 100 x 150
