Presumably two corresponding portals are not actually linked to each other;
each of their warp transforms just happens to point to the other's
position. So it is possible to connect a portal to a position where there
is no corresponding portal, to create a "one-way" portal, or to have a
corresponding portal point somewhere else entirely, for all sorts of
confusing game mechanics. :)
I don't know, but I would try something like this:
portal1->SetWarp(csMatrix3(), movable1->GetFullPosition(),
movable2->GetFullPosition());
portal2->SetWarp(csMatrix3(), movable2->GetFullPosition(),
movable1->GetFullPosition());
And if the portals are differently oriented to each other:
csMatrix3 portal1toportal2 (movable2->GetFullTransform()->GetO2T() *
movable1->GetFullTransform()->GetT2O());
csMatrix3 portal2toportal1 (portal1toportal2.GetInverse());
portal1->SetWarp(portal1toportal2, movable1->GetFullPosition(),
movable2->GetFullPosition());
portal2->SetWarp(portal2toportal1, movable2->GetFullPosition(),
movable1->GetFullPosition());
Let us know when you get a "hall of mirrors" effect working. :)
