From ba0396abf2259b73e83a5871e1fbb4c26f90764d Mon Sep 17 00:00:00 2001 From: havoc Date: Thu, 1 Mar 2007 20:07:20 +0000 Subject: [PATCH] implemented r_shadow_culltriangles cvar (on by default), this improves lighting performance by reducing the amount of geometry to render, it does not add any additional cpu w ork because similar forms of culling were already used on shadow casting triangles (which are now replaced by this), this just applies the same already computed culling to the lighting as well as the shadowing git-svn-id: svn://svn.icculus.org/twilight/trunk/darkplaces@6927 d7cf8633-e32d-0410-b094-e92efae38249 --- client.h | 13 ++ gl_rsurf.c | 217 +++++++++++------- model_shared.c | 21 ++ model_shared.h | 9 +- portals.c | 45 ++-- portals.h | 2 +- r_shadow.c | 589 ++++++++++++++++++++++++++----------------------- r_shadow.h | 3 +- todo | 1 + 9 files changed, 526 insertions(+), 374 deletions(-) diff --git a/client.h b/client.h index 2af844a2..31018173 100644 --- a/client.h +++ b/client.h @@ -126,6 +126,19 @@ typedef struct rtlight_s // surfaces seen by light int static_numsurfaces;
