I need to use (not implement) an array based version of Dijkstras algo .The task is that given a set of line segments(obstacles) and start/end points I have to find and draw the shortest path from start/end point.I have done the calculating part etc..but dont know how to use dijkstras with my code.My code is as follows
class Point
{
public:
int x;
int y;
Point()
{
}
void CopyPoint(Point p)
{
this->x=p.x;
this->y=p.y;
}
};
class NeighbourInfo
{
public:
Point x;
Point y;
double distance;
NeighbourInfo()
{
distance=0.0;
}
};
class LineSegment
{
public:
Point Point1;
Point Point2;
NeighbourInfo neighbours[100];
LineSegment()
{
}
void main()//in this I use my classes and some code to fill out the datastructure
{
int NoOfSegments=i;
for(int j=0;j<NoOfSegments;j++)
{
for(int k=0;k<NoOfSegments;k++)
{
if( SimpleIntersect(segments[j],segments[k]) )
{
segments[j].neighbours[k].distance=INFINITY;
segments[j].neighbours[k].x.CopyPoint(segments[k].Point1);
segments[j].neighbours[k].y.CopyPoint(segments[k].Point2);
cout<<"Intersect"<<endl;
cout<<segments[j].neighbours[k].distance<<endl;
}
else
{
segments[j].neighbours[k].distance=
EuclidianDistance(segments[j].Point1.x,segments[j].Point1.y,segments[k].Point2.x,segments[k ].Point2.y);
segments[j].neighbours[k].x.CopyPoint(segments[k].Point1);
segments[j].neighbours[k].y.CopyPoint(segments[k].Point2);
}
}
}
}
Now I have the distances from each segmnets to all other segments, amd using this data(in neighbourinfo) I want to use array based Dijkstras(restriction ) to trace out the shortest path from start/end points.There is more code , but have shortened the problem for the ease of the reader
Please Help!!Thanks and plz no .net lib/code as I am using core C++ only..Thanks in advance
But I need the array based version(strictly..) I am not suppose to use any other implemntation.
