示例1: ceil
float WaterElevationLayer::WaterElevationCurveData::getCapLength(NodePtr p, vec2d q)
{
vec2d o = p->getPos();
float capLength = 0;
bool largeRiver = false;
for (int i = 0; i < p->getCurveCount(); ++i) {
CurvePtr ipath = p->getCurve(i);
if ((ipath->getAncestor()->getId() == id) == false) {
if (ipath->getType() == LAKE && ipath->getWidth() > 12) {
largeRiver = true;
}
vec2d r = ipath->getXY(p, 1);
if (abs(angle(q - o, r - o) - M_PI) < 0.01) {
continue;
}
float pw = flattenCurve->getType() == RIVER ? 2 * flattenCurve->getWidth() : flattenCurve->getWidth();
