From b73dc36859e03845f702a3e985b536ac9afef63a Mon Sep 17 00:00:00 2001 From: Antonio Vazquez Date: Sat, 3 Jul 2021 17:33:13 +0200 Subject: GPencil: Add weight factor to Offset randomize Now, The weight is used in the randomize parameters of the offset modifier. This is useful to generate effects like explosions. Related to the new Vertex Weight modifiers. --- .../gpencil_modifiers/intern/MOD_gpenciloffset.c | 23 ++++++++++++++-------- 1 file changed, 15 insertions(+), 8 deletions(-) (limited to 'source/blender/gpencil_modifiers') diff --git a/source/blender/gpencil_modifiers/intern/MOD_gpenciloffset.c b/source/blender/gpencil_modifiers/intern/MOD_gpenciloffset.c index cd29a006aae..1a38b91a18b 100644 --- a/source/blender/gpencil_modifiers/intern/MOD_gpenciloffset.c +++ b/source/blender/gpencil_modifiers/intern/MOD_gpenciloffset.c @@ -129,14 +129,6 @@ static void deformStroke(GpencilModifierData *md, } } } - /* Calculate Random matrix. */ - float mat_rnd[4][4]; - float rnd_loc[3], rnd_rot[3]; - float rnd_scale[3] = {1.0f, 1.0f, 1.0f}; - mul_v3_v3v3(rnd_loc, mmd->rnd_offset, rand[0]); - mul_v3_v3v3(rnd_rot, mmd->rnd_rot, rand[1]); - madd_v3_v3v3(rnd_scale, mmd->rnd_scale, rand[2]); - loc_eul_size_to_mat4(mat_rnd, rnd_loc, rnd_rot, rnd_scale); bGPdata *gpd = ob->data; @@ -150,6 +142,21 @@ static void deformStroke(GpencilModifierData *md, if (weight < 0.0f) { continue; } + + /* Calculate Random matrix. */ + float mat_rnd[4][4]; + float rnd_loc[3], rnd_rot[3], rnd_scale_weight[3]; + float rnd_scale[3] = {1.0f, 1.0f, 1.0f}; + + mul_v3_v3fl(rnd_loc, rand[0], weight); + mul_v3_v3fl(rnd_rot, rand[1], weight); + mul_v3_v3fl(rnd_scale_weight, rand[2], weight); + + mul_v3_v3v3(rnd_loc, mmd->rnd_offset, rnd_loc); + mul_v3_v3v3(rnd_rot, mmd->rnd_rot, rnd_rot); + madd_v3_v3v3(rnd_scale, mmd->rnd_scale, rnd_scale_weight); + + loc_eul_size_to_mat4(mat_rnd, rnd_loc, rnd_rot, rnd_scale); /* Apply randomness matrix. */ mul_m4_v3(mat_rnd, &pt->x); -- cgit v1.2.3
