From 08884d258b02e9929919a1913aa763a2eabef285 Mon Sep 17 00:00:00 2001 From: Paramat Date: Thu, 6 Dec 2018 03:56:35 +0000 Subject: [PATCH] Draw all horizons and sky base, in front of stars (#7932) Move star draw to before sun glow texture draw and before sun draw, not currently essential but the logical order. Will be necessary if a 'no far ground' option is added, to draw stars behind the sun. --- src/client/sky.cpp | 200 +++++++++++++++++++++++---------------------- 1 file changed, 102 insertions(+), 98 deletions(-) diff --git a/src/client/sky.cpp b/src/client/sky.cpp index 766f08b1a..ff968444d 100644 --- a/src/client/sky.cpp +++ b/src/client/sky.cpp @@ -228,7 +228,7 @@ void Sky::render() driver->drawIndexedTriangleFan(&vertices[0], 4, indices, 2); } - // Draw far cloudy fog thing + // Draw far cloudy fog thing at and below all horizons for (u32 j = 0; j < 4; j++) { video::SColor c = cloudyfogcolor; vertices[0] = video::S3DVertex(-1, -1.0, -1, 0, 0, 1, c, t, t); @@ -252,22 +252,96 @@ void Sky::render() driver->drawIndexedTriangleFan(&vertices[0], 4, indices, 2); } - // Draw bottom far cloudy fog thing - video::SColor c = cloudyfogcolor; - vertices[0] = video::S3DVertex(-1, -1.0, -1, 0, 1, 0, c, t, t); - vertices[1] = video::S3DVertex( 1, -1.0, -1, 0, 1, 0, c, o, t); - vertices[2] = video::S3DVertex( 1, -1.0, 1, 0, 1, 0, c, o, o); - vertices[3] = video::S3DVertex(-1, -1.0, 1, 0, 1, 0, c, t, o); - driver->drawIndexedTriangleFan(&vertices[0], 4, indices, 2); - // If sun, moon and stars are (temporarily) disabled, abort here if (!m_bodies_visible) return; - driver->setMaterial(m_materials[2]); + // Draw stars before sun and moon to be behind them + do { + driver->setMaterial(m_materials[1]); + // Tune values so that stars first appear just after the sun + // disappears over the horizon, and disappear just before the sun + // appears over the horizon. + // Also tune so that stars are at full brightness from time 20000 to + // time 4000. + float starbrightness = MYMAX(0, MYMIN(1, + (0.25 - fabs(wicked_time_of_day < 0.5 ?
