I can apply the winding number to xy /yz/ zx projection and if are all ok
, the point is inside the 3D Polygon ?
is it as simple ?
For example: i have the point P(Xa,Yb,Zc) and the polygon Pi(Xi,Yi,Zi)
0<=i=>n . I had to do only this :
if ( winding2D(Pi(Xi,Yi),P(Xa,Yb)) &&
return true ;
It will be fantastic ?
