From fe066069d79bd5e7e419373fd8d801792befc857 Mon Sep 17 00:00:00 2001 From: Mads Buvik Sandvei Date: Sun, 25 Sep 2022 21:19:03 +0200 Subject: [PATCH 1/2] /components/ code should not access the stereo manager without checking whether or not stereo is enabled first. Stereo component code should not read settings itself, but rather take settings as parameters. --- apps/openmw/engine.cpp | 52 ++++++++++++++++- apps/openmw/mwrender/pingpongcanvas.cpp | 2 +- apps/openmw/mwrender/sky.cpp | 2 +- apps/openmw/mwrender/transparentpass.cpp | 2 +- apps/openmw/mwrender/water.cpp | 2 +- components/sceneutil/rtt.cpp | 13 +++-- components/sceneutil/shadow.cpp | 7 ++- components/sceneutil/statesetupdater.cpp | 9 +-- components/shader/shadervisitor.cpp | 2 +- components/stereo/multiview.cpp | 25 +++++---- components/stereo/multiview.hpp | 4 +- components/stereo/stereomanager.cpp | 71 +++++------------------- components/stereo/stereomanager.hpp | 31 +++++++++-- components/terrain/material.cpp | 2 +- 14 files changed, 130 insertions(+), 94 deletions(-) diff --git a/apps/openmw/engine.cpp b/apps/openmw/engine.cpp index 3b90f60a0b..f00c40017e 100644 --- a/apps/openmw/engine.cpp +++ b/apps/openmw/engine.cpp @@ -155,7 +155,51 @@ namespace void operator()(osg::GraphicsContext* graphicsContext) override { - Stereo::Manager::instance().initializeStereo(graphicsContext);
