From c00d610e3e704efe27cf35cbfa2ae9d0a48274ec Mon Sep 17 00:00:00 2001 From: Nicholas Bishop Date: Mon, 17 Aug 2009 17:14:37 +0000 Subject: 2.5: * Added icons to viewport shading enum. On a side note, why do we have an icon called "ICON_POTATO" for texture mode? * Fixed clay brush at zero-strength bug, was dividing by zero. Still todo is fixing clay brush strength relative to other brushes. --- source/blender/editors/sculpt_paint/sculpt.c | 37 +++++++++++++++++----------- 1 file changed, 23 insertions(+), 14 deletions(-) (limited to 'source/blender/editors') diff --git a/source/blender/editors/sculpt_paint/sculpt.c b/source/blender/editors/sculpt_paint/sculpt.c index 2a4c553a94c..9931ae15f23 100644 --- a/source/blender/editors/sculpt_paint/sculpt.c +++ b/source/blender/editors/sculpt_paint/sculpt.c @@ -542,12 +542,27 @@ static void point_plane_project(float intr[3], float co[3], float plane_normal[3 VecAddf(intr, intr, p1); } +static int plane_point_side(float co[3], float plane_normal[3], float plane_center[3], int flip) +{ + float delta[3]; + float d; + + VecSubf(delta, co, plane_center); + d = Inpf(plane_normal, delta); + + if(flip) + d = -d; + + return d <= 0.0f; +} + static void do_flatten_clay_brush(Sculpt *sd, SculptSession *ss, const ListBase *active_verts, int clay) { ActiveData *node= active_verts->first; /* area_normal and cntr define the plane towards which vertices are squashed */ float area_normal[3]; float cntr[3], cntr2[3], bstr; + int flip = 0; calc_area_normal(sd, ss, area_normal, active_verts); calc_flatten_center(ss, node, cntr); @@ -558,31 +573,24 @@ static void do_flatten_clay_brush(Sculpt *sd, SculptSession *ss, const ListBase cntr2[0]=cntr[0]+area_normal[0]*bstr*ss->cache->scale[0]; cntr2[1]=cntr[1]+area_normal[1]*bstr*ss->cache->scale[1]; cntr2[2]=cntr[2]+area_normal[2]*bstr*ss->cache->scale[2]; + flip = bstr < 0; } while(node){ float *co= ss->mvert[node->Index].co; - float intr[3], val[3], d; + float intr[3], val[3]; - if(clay) { - float delta[3]; - - VecSubf(delta, co, cntr2); - d = Inpf(area_normal, delta); - - /* Check for subtractive mode */ - if(bstr < 0) - d = -d; - } - - if(!clay || d <= 0.0f) { + if(!clay || plane_point_side(co, area_normal, cntr2, flip)) { /* Find the intersection between squash-plane and vertex (along the area normal) */ point_plane_project(intr, co, area_normal, cntr); VecSubf(val, intr, co); if(clay) { - VecMulf(val, node->Fade / bstr); + if(bstr > FLT_EPSILON) + VecMulf(val, node->Fade / bstr); + else + VecMulf(val, node->Fade); /* Clay displacement */ val[0]+=area_normal[0] * ss->cache->scale[0]*node->Fade; val[1]+=area_normal[1] * ss->cache->scale[1]*node->Fade; @@ -592,6 +600,7 @@ static void do_flatten_clay_brush(Sculpt *sd, SculptSession *ss, const ListBase VecMulf(val, fabs(node->Fade)); VecAddf(val, val, co); + sculpt_clip(sd, ss, co, val); } -- cgit v1.2.3
