From 1a05365812a8245cab7ef4778253ededa7dbfbb8 Mon Sep 17 00:00:00 2001 From: divverent Date: Fri, 15 Jun 2012 08:08:38 +0000 Subject: [PATCH] rename a macro with misleading name, as TriangleOverlapsBox doesn't check for actual triangle/box overlap, but just whether an overlap is possible at all using a bbox check. No functional changes, just search/replace. git-svn-id: svn://svn.icculus.org/twilight/trunk/darkplaces@11829 d7cf8633-e32d-0410-b094-e92efae38249 ::stable-branch::merge=0b2c6dc3a54096a71cc68961e27a486862408b06 --- collision.c | 2 +- gl_rsurf.c | 4 ++-- mathlib.h | 2 +- portals.c | 2 +- r_shadow.c | 8 ++++---- 5 files changed, 9 insertions(+), 9 deletions(-) diff --git a/collision.c b/collision.c index b20e0c34..af0758f5 100644 --- a/collision.c +++ b/collision.c @@ -1036,7 +1036,7 @@ void Collision_TraceBrushTriangleMeshFloat(trace_t *trace, const colbrushf_t *th { for (i = 0;i < numtriangles;i++, element3i += 3) { - if (TriangleOverlapsBox(vertex3f + element3i[0]*3, vertex3f + element3i[1]*3, vertex3f + element3i[2]*3, segmentmins, segmentmaxs)) + if (TriangleBBoxOverlapsBox(vertex3f + element3i[0]*3, vertex3f + element3i[1]*3, vertex3f + element3i[2]*3, segmentmins, segmentmaxs)) { VectorCopy(vertex3f + element3i[0] * 3, points[0].v);
