From 26fc44aa32f4e821302f8b9cf577439963b40e1a Mon Sep 17 00:00:00 2001 From: ehofman <ehofman> Date: Mon, 18 Jul 2005 16:58:52 +0000 Subject: [PATCH] Harald JOHNSEN: Changes ======= - shadowvolume.cxx, renderer.cxx : - reduced the polygon offset a bit to eliminate some artifact ; - changed again the cleanup code for objects inside a tile because it could crash on rare occasion ; - the culling of shadow casters has been rewritten to traverse the scene graph, it should be a bit faster when there is a lot of objects ; - the range selector was not correctly handled, sometimes the wrong LOD was casting shadows. - added the option to display aircraft's transparent objects after the shadows, this will reduce the problem of shadows being hidden by the transparent object (propeller disk, rotor, etc). A side effect is that aircraft's transparent objects won't receive shadows anymore. This is usually a good thing except when the aircraft use a 'transparent' texture where it should not. A transparent texture in the plib context is a texture with an alpha channel or a material with alpha <= 0.99. - model.cxx, animation.cxx, shadowvolume.cxx : - added an optional <condition> under the <noshadow> animation - tower.cxx - correct a rare bug where all occurences of the aircraft are not deleted from the departure list causing a crash in FGTower::CheckDepartureList function. --- gui/dialogs/rendering.xml | 11 +++++++++++ preferences.xml | 1 + 2 files changed, 12 insertions(+) diff --git a/gui/dialogs/rendering.xml b/gui/dialogs/rendering.xml index a59b34c37..1864ddf29 100644 --- a/gui/dialogs/rendering.xml +++ b/gui/dialogs/rendering.xml @@ -203,6 +203,8 @@ </group> <group> <layout>vbox</layout> + <group> + <layout>hbox</layout> <checkbox> <halign>left</halign> <label>Aircraft</label> @@ -211,6 +213,15 @@ <command>dialog-apply</command> </binding> </checkbox> + <checkbox> + <halign>left</halign> + <label>Transparency</label> + <property>/sim/rendering/shadows-ac-transp</property> + <binding> + <command>dialog-apply</command> + </binding> + </checkbox> + </group> <checkbox> <halign>left</halign> <label>Scenery objects</label> diff --git a/preferences.xml b/preferences.xml index 9ee56cbab..8518b3be2 100644 --- a/preferences.xml +++ b/preferences.xml @@ -51,6 +51,7 @@ Started September 2000 by David Megginson, david@megginson.com <distance-attenuation type="bool">false</distance-attenuation> <draw-otw type="bool">true</draw-otw> <shadows-ac type="bool">false</shadows-ac> + <shadows-ac-transp type="bool">false</shadows-ac-transp> <shadows-ai type="bool">false</shadows-ai> <shadows-to type="bool">false</shadows-to> <shadows-debug type="bool">false</shadows-debug>
