I am trying to convert 3D coordinates of a point in plane object to 2D coordinates considering viewport width and height. I am writing the code in c++.
While going through 3Ds max documentation I found function "MapViewToScreen", Will this function be enough? If so how to implement it. If there are any other methods too please suggest.
Check the link map-world-point-to-viewport-coordinates
Basically what you need to do is
//get Transfromation matrix of the plane
Matrix3 tmMatrix = inode->GetObjectTM( GetCOREInterface()->GetTime() );
ViewExp& vpt = GetCOREInterface()->GetActiveViewExp();
GraphicsWindow *gwindow= vpt.getGW();
gwindow->setTransform( Matrix3(1) );
//Your required point, consider only the X and Y part
IPoint3 out; // X and Y from the bottom left corner
Point3 in( your_3d_point * tmMatrix );
gwindow->hTransPoint(&in, &out);
