示例1: groupCurveLength
float BccWorld::groupCurveLength(GeometryArray * geos)
{
float sum = 0.f;
const unsigned n = geos->numGeometries();
unsigned i = 0;
for(;i<n;i++) {
BezierCurve * c = static_cast<BezierCurve *>(geos->geometry(i));
sum += c->length();
}
return sum;
}示例2: createCurveGeometryFromFile
bool BccWorld::createCurveGeometryFromFile()
{
if(!readCurveDataFromFile()) return false;
m_allGeo = new GeometryArray;
m_allGeo->create(m_curves->numCurves());
const unsigned n = m_curves->numCurves();
m_allGeo = new GeometryArray;
m_allGeo->create(n);
unsigned * cc = m_curves->counts();
Vector3F * cvs = m_curves->points();
m_totalCurveLength = 0.f;
CurveBuilder cb;
unsigned ncv;
unsigned cvDrift = 0;
unsigned i, j;
for(i=0; i< n; i++) {
ncv = cc[i];
for(j=0; j < ncv; j++)
