How can I get the world coordinates of a point of a polygonal object? I mean, even if it is rotated, how can I get the global (world) coordinates of any point?
TIA

hi rui, you need to get the global matrix in coffee

var mat=op->GetMg();

then you need to multiply the points position by the global matrix:

var pos=mat->GetMulP(point);

if you then need to get a global points position but in local space what you need to do is invert the global matrix of the object first before you multiply the point so

var mat=op->GetMg();
mat->Invert();
var pos=mat->GetMulP(pointinglobalspace);

hope this helps.
