I am trying to get the edge vertices of objects (from a certain view), but it is giving me trouble, can anyone point me in the right direction? (the variable outlineVertices is always 0)

+ Code Snippet

        int outlineVertices = 0;
        dbLoadObject("box.X",1);

	dbMakeMeshFromObject(1,1);

	dbAddMeshToVertexData(1);

	dbLockVertexDataForMesh(1);

        dbMakeVector3(1);
	dbSetVector3(1,-100,100,0); // LIGHT POSITION !!!

	for(int i = 0; i < dbGetVertexDataVertexCount(); i++) {
		dbMakeVector3(2);
		dbSetVector3(2, dbGetVertexDataNormalsX(i),dbGetVertexDataNormalsY(i),dbGetVertexDataNormalsZ(i));
		if(dbACOS(dbDotProductVector3(1,2)) <= 0) {
			outlineVertices++;
		}

	}

	dbUnlockVertexData();
