From d4d292258e31eee6d639106147758f39deae63e3 Mon Sep 17 00:00:00 2001 From: Ricky Curtice Date: Thu, 10 Mar 2011 22:07:06 -0800 Subject: Squared all dist_vec() based comparisons and other dist_vec() operations where sensible. Not all instances of dist_vec() were squared, only those where it wouldn't (hopefully) change the functionality. --- indra/newview/llworld.cpp | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'indra/newview/llworld.cpp') diff --git a/indra/newview/llworld.cpp b/indra/newview/llworld.cpp index 8f7197c607..a21a7eac9e 100644 --- a/indra/newview/llworld.cpp +++ b/indra/newview/llworld.cpp @@ -1446,6 +1446,8 @@ static LLVector3d unpackLocalToGlobalPosition(U32 compact_local, const LLVector3 void LLWorld::getAvatars(uuid_vec_t* avatar_ids, std::vector* positions, const LLVector3d& relative_to, F32 radius) const { + F32 radius_squared = radius * radius; + if(avatar_ids != NULL) { avatar_ids->clear(); @@ -1463,7 +1465,7 @@ void LLWorld::getAvatars(uuid_vec_t* avatar_ids, std::vector* positi for (S32 i = 0; i < count; i++) { LLVector3d pos_global = unpackLocalToGlobalPosition(regionp->mMapAvatars.get(i), origin_global); - if(dist_vec(pos_global, relative_to) <= radius) + if(dist_vec_squared(pos_global, relative_to) <= radius_squared) { if(positions != NULL) { @@ -1491,7 +1493,7 @@ void LLWorld::getAvatars(uuid_vec_t* avatar_ids, std::vector* positi if(uuid.isNull()) continue; LLVector3d pos_global = pVOAvatar->getPositionGlobal(); - if(dist_vec(pos_global, relative_to) <= radius) + if(dist_vec_squared(pos_global, relative_to) <= radius_squared) { bool found = false; uuid_vec_t::iterator sel_iter = avatar_ids->begin(); -- cgit v1.2.3
