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/llcharacter/llbvhloader.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'indra/llcharacter/llbvhloader.cpp') diff --git a/indra/llcharacter/llbvhloader.cpp b/indra/llcharacter/llbvhloader.cpp index 532a2c1b0d..a340bab6d3 100644 --- a/indra/llcharacter/llbvhloader.cpp +++ b/indra/llcharacter/llbvhloader.cpp @@ -1196,7 +1196,7 @@ void LLBVHLoader::optimize() if (ki_prev == ki_last_good_pos) { joint->mNumPosKeys++; - if (dist_vec(LLVector3(ki_prev->mPos), first_frame_pos) > POSITION_MOTION_THRESHOLD) + if (dist_vec_squared(LLVector3(ki_prev->mPos), first_frame_pos) > POSITION_MOTION_THRESHOLD * POSITION_MOTION_THRESHOLD) { pos_changed = TRUE; } @@ -1209,12 +1209,12 @@ void LLBVHLoader::optimize() LLVector3 current_pos(ki->mPos); LLVector3 interp_pos = lerp(current_pos, last_good_pos, 1.f / (F32)numPosFramesConsidered); - if (dist_vec(current_pos, first_frame_pos) > POSITION_MOTION_THRESHOLD) + if (dist_vec_squared(current_pos, first_frame_pos) > POSITION_MOTION_THRESHOLD * POSITION_MOTION_THRESHOLD) { pos_changed = TRUE; } - if (dist_vec(interp_pos, test_pos) < POSITION_KEYFRAME_THRESHOLD) + if (dist_vec_squared(interp_pos, test_pos) < POSITION_KEYFRAME_THRESHOLD * POSITION_KEYFRAME_THRESHOLD) { ki_prev->mIgnorePos = TRUE; numPosFramesConsidered++; -- cgit v1.2.3
