示例1: vec
// Calculate (normalized) edge vectors.
// edges[i] gives edge between point i+1 and i.
Foam::tmp<Foam::vectorField> Foam::faceTriangulation::calcEdges
(
const face& f,
const pointField& points
)
{
tmp<vectorField> tedges(new vectorField(f.size()));
vectorField& edges = tedges();
forAll(f, i)
{
point thisPt = points[f[i]];
point nextPt = points[f[f.fcIndex(i)]];
vector vec(nextPt - thisPt);
vec /= mag(vec) + VSMALL;
edges[i] = vec;
}示例2: ePrev
// Test face for (almost) convexeness. Allows certain convexity before
// complaining.
// For every two consecutive edges calculate the normal. If it differs too
// much from the average face normal complain.
bool Foam::combineFaces::convexFace
(
const scalar minConcaveCos,
const pointField& points,
const face& f
)
{
// Get outwards pointing normal of f.
vector n = f.normal(points);
n /= mag(n);
// Get edge from f[0] to f[size-1];
vector ePrev(points[f.first()] - points[f.last()]);
scalar magEPrev = mag(ePrev);
ePrev /= magEPrev + VSMALL;
forAll(f, fp0)
{
// Get vertex after fp
label fp1 = f.fcIndex(fp0);
// Normalized vector between two consecutive points
vector e10(points[f[fp1]] - points[f[fp0]]);
scalar magE10 = mag(e10);
e10 /= magE10 + VSMALL;
if (magEPrev > SMALL && magE10 > SMALL)

const DynamicList<point>& u,
const scalarField& dist,
scalarField& weights
) const
{

// recompute theta, the theta computed previously are not robust
