si tiene in considerazione una mappa ListOfDuplexVert<Key,int>, alla quale gli viene associato il seguente significato:
|
||||
Key:è una coppia (int,TexCoord) formata da un int che rappresenta l'indice del vettore nella mesh originale e la sua
|
||||
coordinata di texture. tale coppia rappresenta una chiave, essendo univoca in tutta la mesh. Non è possibile che
|
||||
si incontrino due vertici che hanno solito indice di vertice e solite coordinate di texture, se un vertice di
|
||||
questo tipo esistesse allora i due vertici rappresenterebbero lo stesso vertice.
|
||||
int:è l'indice del vertice inserito all'interno del vettore VectorOfVertexType<VertexType>
|
||||
|
||||
Nel vertice VectorOfVertexType vengono inseriti tutti i vertici appartenenti alla mesh + i k vertici dublicati. la scelta
|
||||
di tali vertici va in base alla seguente regola:
|
||||
se un vertice con indice x(originale) ha più di una coordinata di texture allora tale vertice viene duplicato e
|
||||
inserito in ListOfDuplexVert e in VectorOfVertexType(in VectorOfVertexType, l'inserimento del doppio vertice non
|
||||
sarebbe necessario, però viene fatto per comodità, in caso contrario dovremmo cercare il vertice dentro il vettore).
|
||||
|
||||
rappresentazione grafica:
|
||||
|
||||
ListOfDuplexVert VectorOfVertexType

||||

|
||||
|key1| -> index1 --------- |vertex1|

|

|

questo tipo di struttura permette di selezionare l'indice del vertice in VectorOfVertexType con costo O(1).
|
||||
|
||||
<<code:>>
|
||||
questo pezzo di codice itera su tutte le facce della mesh per riempire la mappa e il vettore.
|
||||
per ogni faccia e per ogni vertice di faccia costruisce la coppia (indice,texture), controlla se
|
||||
all'interno di ListOfDuplexVert esiste già in tal caso non fa niente, in caso contrario aggiunte la
|
||||
coppia in ListOfDuplexVert e l'oggetto VertexType in VectorOfVertexType associando al valore della
|
||||
chiave (indice,texture) l'indice del vertice a cui punta.
|
||||
|
||||
alla fine vengono duplicati solamente quei vertici che hanno più coordinate di texture.
|
||||
|
||||
c'e' da tenere presente che il codice appena descritto viene eseguito SOLAMENTE se la mesh contiene texture e
|
||||
se dalla dialog di exporter viene spuntato il salvataggio delle texture. In caso contrario non esegue niente e tratta
|
||||
solamente i vertici che sono presenti nella mesh senza creare duplicati. Le informazioni presenti in assenza di
|
||||
texture sono piu' che sufficienti.
