From 78b5d66af8e29ddfd234fb07bd36be785702901e Mon Sep 17 00:00:00 2001 From: Alexander Romanov Date: Fri, 14 Apr 2017 18:13:44 +0300 Subject: Object Info node support for GLSL mode and the internal render Object Info node can be useful to give some variation to a single material assigned to multiple instances. This patch adds support for Viewport and BI. {F499530} Example: {F499528} Reviewers: merwin, brecht, dfelinto Reviewed By: brecht Subscribers: duarteframos, fclem, homyachetser, Evgeny_Rodygin, AlexKowel, yurikovelenov Differential Revision: https://developer.blender.org/D2425 --- source/blender/blenkernel/intern/object_dupli.c | 17 ++++++ source/blender/blenlib/BLI_hash.h | 66 ++++++++++++++++++++++ source/blender/gpu/GPU_material.h | 5 +- source/blender/gpu/intern/gpu_codegen.c | 2 + source/blender/gpu/intern/gpu_draw.c | 23 +++++++- source/blender/gpu/intern/gpu_material.c | 14 ++++- source/blender/gpu/intern/gpu_shader.c | 1 + .../blender/gpu/shaders/gpu_shader_material.glsl | 10 ++-- source/blender/makesdna/DNA_object_types.h | 2 + source/blender/makesrna/intern/rna_object.c | 4 ++ .../nodes/shader/nodes/node_shader_object_info.c | 12 +++- source/blender/render/extern/include/RE_pipeline.h | 2 +- .../blender/render/extern/include/RE_shader_ext.h | 4 ++ .../blender/render/intern/include/render_types.h | 2 + .../blender/render/intern/source/renderdatabase.c | 9 +++ source/blender/render/intern/source/shadeoutput.c | 10 ++++ source/blenderplayer/bad_level_call_stubs/stubs.c | 1 + source/gameengine/Ketsji/BL_BlenderShader.cpp | 2 +- 18 files changed, 175 insertions(+), 11 deletions(-) create mode 100644 source/blender/blenlib/BLI_hash.h (limited to 'source') diff --git a/source/blender/blenkernel/intern/object_dupli.c b/source/blender/blenkernel/intern/object_dupli.c index e3b801b3193..eb7abc2f004 100644 --- a/source/blender/blenkernel/intern/object_dupli.c +++ b/source/blender/blenkernel/intern/object_dupli.c @@ -64,6 +64,7 @@ #include "BLI_strict_flags.h" +#include "BLI_hash.h" /* Dupli-Geometry */ @@ -180,6 +181,22 @@ static DupliObject *make_dupli(const DupliContext *ctx, if (ob->type == OB_MBALL) dob->no_draw = true; + /* random number */ + /* the logic here is designed to match Cycles */ + dob->random_id = BLI_hash_string(dob->ob->id.name + 2); + + if (dob->persistent_id[0] != INT_MAX) { + for(i = 0; i < MAX_DUPLI_RECUR*2; i++) + dob->random_id = BLI_hash_int_2d(dob->random_id, (unsigned int)dob->persistent_id[i]); + } + else { + dob->random_id = BLI_hash_int_2d(dob->random_id, 0); + } + + if (ctx->object != ob) { + dob->random_id ^= BLI_hash_int(BLI_hash_string(ctx->object->id.name + 2)); + } + return dob; } diff --git a/source/blender/blenlib/BLI_hash.h b/source/blender/blenlib/BLI_hash.h new file mode 100644 index 00000000000..551143f5d72 --- /dev/null +++ b/source/blender/blenlib/BLI_hash.h @@ -0,0 +1,66 @@ +/* + * ***** BEGIN GPL LICENSE BLOCK ***** + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version 2 + * of the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
