From 1ea97e5552bfb9c9845a7cfc5e0a2ce5ecf23cb4 Mon Sep 17 00:00:00 2001 From: Martin Poirier Date: Sun, 1 Oct 2006 19:45:37 +0000 Subject: Patch: [ #5036 ] IPO Curve Mirroring by Joshua Leung (aligorith) This patch adds the feature of IPO curve mirroring. It mirrors the selected keyframes in the active ipo curves over a user-nominated mirror-line. Options are: - Mirror over current frame - Mirror over vertical axis (X = 0) - Mirror over horizontal axis (Y = 0) Functionality can be accessed from: - Hotkey M in IPO editor - Submenu in header of IPO editor --- source/blender/include/BSE_editipo.h | 2 + source/blender/src/editipo.c | 86 ++++++++++++++++++++++++++++++++++++ source/blender/src/header_ipo.c | 31 +++++++++++++ source/blender/src/space.c | 4 ++ 4 files changed, 123 insertions(+) (limited to 'source') diff --git a/source/blender/include/BSE_editipo.h b/source/blender/include/BSE_editipo.h index 8ae27f26e7d..2f98c047dc9 100644 --- a/source/blender/include/BSE_editipo.h +++ b/source/blender/include/BSE_editipo.h @@ -96,6 +96,8 @@ void join_ipo_menu(void); void join_ipo(int mode); void ipo_snap_menu(void); void ipo_snap(short event); +void ipo_mirror_menu(void); +void ipo_mirror(short event); void mouse_select_ipo(void); void sethandles_ipo(int code); void select_ipo_bezier_keys(struct Ipo *ipo, int selectmode); diff --git a/source/blender/src/editipo.c b/source/blender/src/editipo.c index d51c17c3b63..0ea16bb64cb 100644 --- a/source/blender/src/editipo.c +++ b/source/blender/src/editipo.c @@ -100,6 +100,7 @@ #include "BDR_drawobject.h" #include "BDR_editobject.h" +#include "BDR_editcurve.h" // for bezt_compare #include "BSE_trans_types.h" #include "BSE_editipo_types.h" @@ -3073,6 +3074,91 @@ void ipo_snap(short event) BIF_undo_push("Snap Ipo"); } +void ipo_mirror_menu(void) +{ + int mode = 0; + mode= pupmenu("Mirror Over%t|Current Frame%x1|Vertical Axis%x2|Horizontal Axis%x3"); + + if (mode == -1) return; + + ipo_mirror(mode); +} + +void ipo_mirror(short mode) +{ + EditIpo *ei; + BezTriple *bezt; + + int a, b; + int ok, ok2; + float diff; + + /* what's this for?
