detect collision in matlab

In order to detect collision in Matlab, we need to have a representation of the objects in space. One common representation is to use a 3D model, which defines the object as a set of vertices and faces.

One approach to detecting collision between two objects is to check if any of the vertices of one object lies within the other object. This can be done using the inpolyhedron function from the 3D modeling toolbox.

Here is an example code snippet:

main.m
% define two 3D objects as sets of vertices and faces
obj1_vertices = [...];
obj1_faces = [...];

obj2_vertices = [...];
obj2_faces = [...];

% create polyhedron objects from the vertices and faces
obj1_polyhedron = polyhedron(obj1_vertices, obj1_faces);
obj2_polyhedron = polyhedron(obj2_vertices, obj2_faces);

% check if any vertices of obj1 are inside obj2
collision_detected = any(inpolyhedron(obj2_polyhedron, obj1_vertices));

% if no collision detected, check if any vertices of obj2 are inside obj1
if (~collision_detected)
    collision_detected = any(inpolyhedron(obj1_polyhedron, obj2_vertices));
end

% display the result
if (collision_detected)
    disp('Collision detected!');
else
    disp('No collision detected.');
end

Note that this approach can be computationally expensive and may not be suitable for complex 3D models or real-time applications. Alternative approaches include bounding boxes or hierarchical collision detection algorithms.
