[Bug 10435] New: Portal 1.0: Portals don't always appear correctly ( clipping plane / frustum not being respected?)

http://bugs.winehq.org/show_bug.cgi?id=10435

Summary: Portal 1.0: Portals don't always appear correctly
                    (clipping plane / frustum not being respected?)
           Product: Wine
           Version: 0.9.49.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: wine-directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Often in Portal, instead of seeing through a pair of portals, you end up seeing
what's behind the destination portal - but this depends on the viewing angle
and distance.

It would appear that the clipping plane/frustum (whatever) when the portal is
rendered is modified with respect to the player's position in Portal; or
perhaps it *isn't* modified and is instead rendered with the same clipping
frustum as the main viewpoint.

Confirming that I see this too, although I was never sure if this was a Wine
thing or a Portal thing (having never played that game in Windows).

Same here too. Might be game's bug. Need to test this on windows.

This is not the game's bug, the portals work correctly in Windows (tested on a
friend's machine with very similar hardware)

Might have something to do with these messages:

If it draws the portal onto a texture then blits it.

I don't think it has to do with those messages, that's probably a different
bug/missing feature - the problem here seems to be that the clipping frustrum
is incorrect when rendering the portal contents - the z clipping happens behind
the point it should... I'd look myself if I had any knowledge of Direct3D or
the Wine code-base at all... And more time... :)

I see this as well, especially when you put the portals on the something that
can move, such as the parts of the wall that move during the momentum trials
near the beginning of the game.

Is this still an issue in current (1.0-rc5 or newer) wine?

Troublesome portal in wine-1.0-rc5

Yes the problem remains in the latest Wine, see attached screenshot showing a
broken portal in wine-1.0-rc5.

Here too.
Not only that but from time to time the background or terrain where portals
can't be added are showed purple. Maybe the purple bug is a copy of
http://bugs.winehq.org/show_bug.cgi?id=11948 but just wanted to confirm the
portal-angle-view bug.

Just did a quick test on a couple of levels with portals in various directions
and this seems to be fixed.  This was with default Wine and game settings (if I
recall correctly, different settings caused noticable breaking/fixing of
various glitches in the past).
