From 1abdf8d61e1bdb99b5e2618d5556f170265e5679 Mon Sep 17 00:00:00 2001 From: dooglus Date: Thu, 12 Apr 2007 12:19:19 +0000 Subject: [PATCH] At last - a real change! I think this is the bug I've been looking for. Don't add positions into the mix when transforming tangents; keep positions and tangents separate. We still want to transform the tangents, like we do for positions, but don't add tangents to positions. git-svn-id: http://svn.voria.com/code@462 1f10aa63-cdf2-0310-b900-c93c546f37ac --- synfig-core/trunk/src/synfig/valuenode_bline.cpp | 16 ++++++---------- 1 file changed, 6 insertions(+), 10 deletions(-) diff --git a/synfig-core/trunk/src/synfig/valuenode_bline.cpp b/synfig-core/trunk/src/synfig/valuenode_bline.cpp index 2435814..05cb1e4 100644 --- a/synfig-core/trunk/src/synfig/valuenode_bline.cpp +++ b/synfig-core/trunk/src/synfig/valuenode_bline.cpp @@ -592,13 +592,13 @@ ValueNode_BLine::operator()(Time t)const #ifdef COORD_SYS_RADIAL_TAN_INTERP // this I don't understand. why add on this bit ---v - transform_coords(blp_here_on.get_tangent1() + blp_here_on.get_vertex(), trans_on_t1, on_coord_origin, on_coord_sys); - transform_coords(blp_here_off.get_tangent1() + blp_here_off.get_vertex(), trans_off_t1, off_coord_origin, off_coord_sys); + transform_coords(blp_here_on.get_tangent1(), trans_on_t1, Point::zero(), on_coord_sys); + transform_coords(blp_here_off.get_tangent1(), trans_off_t1, Point::zero(), off_coord_sys); if(blp_here_on.get_split_tangent_flag()) { - transform_coords(blp_here_on.get_tangent2() + blp_here_on.get_vertex(), trans_on_t2, on_coord_origin, on_coord_sys); - transform_coords(blp_here_off.get_tangent2() + blp_here_off.get_vertex(), trans_off_t2, off_coord_origin, off_coord_sys); + transform_coords(blp_here_on.get_tangent2(), trans_on_t2, Point::zero(), on_coord_sys); + transform_coords(blp_here_off.get_tangent2(), trans_off_t2, Point::zero(), off_coord_sys); } #endif // Convert current point @@ -614,15 +614,11 @@ ValueNode_BLine::operator()(Time t)const #ifdef COORD_SYS_RADIAL_TAN_INTERP untransform_coords(INTERP_FUNCTION(trans_off_t1,trans_on_t1,amount), - untrans_curr_t1, curr_coord_origin, curr_coord_sys); - untrans_curr_t1 -= untrans_curr_point; + untrans_curr_t1, Point::zero(), curr_coord_sys); if(blp_here_on.get_split_tangent_flag()) - { untransform_coords(INTERP_FUNCTION(trans_off_t2,trans_on_t2,amount), - untrans_curr_t2, curr_coord_origin, curr_coord_sys); - untrans_curr_t2 -= untrans_curr_point; - } + untrans_curr_t2, Point::zero(), curr_coord_sys); #endif blp_here_now.set_vertex(untrans_curr_point); -- 2.7.4
