示例1: getClosestPointUtil
//----------------------------------------------------------
// http://local.wasp.uwa.edu.au/~pbourke/geometry/pointline/
static ofPoint getClosestPointUtil(const ofPoint& p1, const ofPoint& p2, const ofPoint& p3, float* normalizedPosition) {
// if p1 is coincident with p2, there is no line
if(p1 == p2) {
if(normalizedPosition != NULL) {
*normalizedPosition = 0;
}
return p1;
}
float u = (p3.x - p1.x) * (p2.x - p1.x);
u += (p3.y - p1.y) * (p2.y - p1.y);
// perfect place for fast inverse sqrt...
float len = (p2 - p1).length();
u /= (len * len);
// clamp u
if(u > 1) {
u = 1;
} else if(u < 0) {
u = 0;
}
if(normalizedPosition != NULL) {
*normalizedPosition = u;
}
return p1.getInterpolated(p2, u);
}示例2: drawPointOnLine
