I have the following question regarding getting the positions of a particular edge of a 3D object.
Example, I have a track (car game) and I want to calculate, through a C # script, both sides of the track. See image:
I have the positions of all the vertices (which also exist in the center of the track), however I want the vertices that are only at the edge of the track.
Does anyone know which calculation to use?
With the data you provided, it seems impossible to solve the problem, however if the track has constant width (or you can know the width of the track at a particular vertex) there is a solution.
At each vertex you will check if there is any other vertex that is a distance from a track . Here is an example:
Vertices[] arrayVertices;
float larguraDaPista = 5;
for(int i = 0; i < arrayVertices.size(); i++){
Vertice verticeATestar = arrayVertices[i];
for(int j = i; j < arrayVertices.size(); j++){
Vertice verticeParaComparar = arrayVertices[j];
if (Vector3.Distance(verticeATestar, verticeParaComparar) == larguraDaPista){
//São ambos limites
}
}
}
