I have been experiencing a difficulty in designing a room with 4 walls to be preseted in 3D .a help would be much appreciated as I'm stuck in my middle of thesis.

With regards ,

A cube has 6 walls, if you consider floor and ceiling.

The example you are showing contains much more details than "4 walls". It is not clear what "design a room" exactly means. Adding "furnature" can be implemented as complicated as you want. You cannot expect, that the forum writes you a 3D modelling software. So please post, what you have tried so far. I've asked already, how your inputs are defined. But your current explanations are far too abstract to allow to help you.

I'm sorry for being too vague in my information,i need to design a room with 6 walls as you have said for testing refractions,reflections caused in a closed room with increasing complications as the process goes on like 1st only a cube with 6 walls,later with some windows and cupboards etc.

I'm sorry once again, Thank you so much for the help i have received from this forum .it has really taken me a step near to my goal.

> can you help in finding the patch

I can help you understand the concept so you can apply it to your thesis work.

There are multiple ways to draw 2D rectangles or 3D cubes within 3D axes. I'll use patch but also see surf which isn't much different from patch.

First read through the documentation page for the patch function and look at the examples. If you want to show only the edges of the rectangles/cubes, then set the FaceColor of surf/patch objects to None.

Example

% 2D wall
x = [-5 5 5 -5];
y = [6 6 6 6];
z = [0 0 3 3];

Just by looking at the [x,y,z] coordinates above, imagine where this wall will be in 3D axes. If you can't imagine where it will be then you don't understand a 3D coordinate systems and you'll need to fill that gap before you're able to move on.

figure()

patch(x,y,z,[1 1 1],'FaceColor','none','EdgeColor','m','LineWidth',2)

view(3)

xlabel('x')

ylabel('y')

zlabel('z')

grid on

axis equal % important

xlim([-6 6])

ylim([-6 6])

zlim([-1 6])
