From 28fe1dc0042c6998dacdfd271991b3ba1964f1c4 Mon Sep 17 00:00:00 2001 From: Ragnvald Maartmann-Moe IV Date: Sun, 9 Sep 2001 19:37:07 +0000 Subject: [PATCH] Tweak rocket trails. Uglier, but don't bog down rocket snipers. Also a couple tiny optimizations and cleanups. --- libs/video/renderer/gl/gl_dyn_lights.c | 2 +- libs/video/renderer/gl/gl_dyn_part.c | 6 +- libs/video/renderer/gl/gl_rmain.c | 102 ++++++++++++------------- libs/video/renderer/gl/gl_rsurf.c | 2 +- libs/video/targets/vid_common_gl.c | 73 ++++++++---------- 5 files changed, 88 insertions(+), 97 deletions(-) diff --git a/libs/video/renderer/gl/gl_dyn_lights.c b/libs/video/renderer/gl/gl_dyn_lights.c index 4f40b867d..a9e32731b 100644 --- a/libs/video/renderer/gl/gl_dyn_lights.c +++ b/libs/video/renderer/gl/gl_dyn_lights.c @@ -62,7 +62,7 @@ R_InitBubble () bub_cos = bubble_costable;
