From: ehofman Date: Sun, 22 May 2005 08:09:08 +0000 (+0000) Subject: Harald JOHSNEN: X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=7b5d49ef60733314a280b766a34f9ca448b956f6;p=simgear.git Harald JOHSNEN: Changes ======= - correct the transparency probleme when old 3d clouds were enabled (rendering context with an alpha channel) - changed rain cone orientation, it can now be viewed from helicopter or chase view (still not tower view) - clouds are a bit more yellow/red at dawn/dusk - weather data is now correctly propagated to the interpolator, this correct visibility, wind, etc - the 'metar' weather scenario now immedialty reuse the real metar data - real metar no more overwrite custom weather scenario --- diff --git a/simgear/environment/visual_enviro.cxx b/simgear/environment/visual_enviro.cxx index 0c5192eb..8855689a 100644 --- a/simgear/environment/visual_enviro.cxx +++ b/simgear/environment/visual_enviro.cxx @@ -388,14 +388,14 @@ void SGEnviro::DrawCone2(float baseRadius, float height, int slices, bool down, } // TODO:check alt vs layer -void SGEnviro::drawRain(double pitch, double roll, double speed, double rain_norm) { +void SGEnviro::drawRain(double pitch, double roll, double heading, double speed, double rain_norm) { glBindTexture(GL_TEXTURE_2D, 0);
