示例1: calculatePolylineFromCP
void calculatePolylineFromCP(const std::vector<Vector2d> &aCPs)
{
// build a polyline from our control points, for visible.
polyline.clear();
polyline.setPosition(Vector2d(400, 400) );
for (unsigned int i = 0; i < aCPs.size(); ++i)
polyline.addVertex( aCPs[i] );
// to do the evaluation of the curve, get an array pos on the curve
std::vector<Vector2d> aPos;
for (int i = 0; i <= 200; ++i)
aPos.push_back( evaluateCubicBezier_deCasteljau(aCPs, i * 1.0f / 200) );
// we use those pos on the curve to simulate a curve by a polyline, for visible.
curvePolyline.clear();
curvePolyline.setPosition(Vector2d(400, 400) );
for (unsigned int i = 0; i < aPos.size(); ++i)
curvePolyline.addVertex( aPos[i] );
