示例1: SetFromFaces
void Box::SetFromFaces(FaceSet& faces) {
if (faces.Size() == 0) return;
// initialize max and min with the first member of the face set
FaceList::iterator itr = faces.begin();
Vector<3,float> max((*itr)->vert[0]);
Vector<3,float> min(max);
// find the boundary values
for (; itr != faces.end(); itr++) {
for (int i=0; i<3; i++) {
Vector<3,float> v = (*itr)->vert[i];
for (int j=0; j<3; j++)
if (v[j] < min[j]) min[j] = v[j];
else if (v[j] > max[j]) max[j] = v[j];
}
}
// set box center
center = (max - min) / 2 + min;
// set corner vector
corner = max - center;
// compute the corners
float x = corner[0];
float y = corner[1];
float z = corner[2];
SetCorner(1,1,1, center+Vector<3,float>( x, y, z));
SetCorner(1,1,0, center+Vector<3,float>( x, y,-z));
