Help for plotting a moving object
显示 更早的评论
Dear all,
I am doing a project about multi-lanes highway simulation, and to get starting, I am looking for some literatures to guide me how to draw/plot moving objects, like cars, in Matlab or does someone have the code ? Please help me ! Thanks a lot

hi every one, how can I model a moving train scenario that move linearly from point 1 to point 2

It may sound complicated but it's really easy to draw/plot moving object in MATLAB.
h=[];
for j=1:TimeSteps
delete(h)
h=plot (x.position(1,j), y.position(1,j))
drawnow;
end
TimeSteps: being duration of the simulation, x, y are the x and y position of your vehicle for each timestep.
I have experience building traffic simulator in MATLAB, so if you have any more questions don't hesitate to ask.

Hi, You are very welcome! I tried sending you my email through private message but it didn't work. :( Maybe you can send me your email address or you can just ask me any questions you have here. Cheers.

And what is the point of "h"? You probably want h=plot(.....

"how to move the vehicles in a specific direction with speed"
Given a direction as an angle, and given a speed, you can use pol2cart to convert the angle and speed to x and y offsets. You would add those offsets to the coordinates of your objects at each step and update the coordinates in the plot.

What are you observing when you implemented the strategy I described in https://www.mathworks.com/matlabcentral/answers/77140-help-for-plotting-a-moving-object#comment_525848 ?

You should consider creating one hgtransform for each object to be drawn, and then set the Parent of the object to be drawn to be the hgtransform. Then when you need to move or rotate the object, change the transform matrix of the hgtransform; you might find hgmaketform() handy for that.
