From c3e1fce77552b5626d2939710cb6d0020891d218 Mon Sep 17 00:00:00 2001 From: Brecht Van Lommel Date: Mon, 21 May 2012 12:52:28 +0000 Subject: Cycles: add Object Info node, with outputs object location, object/material pass index, and a random number unique to the instance of the object. This can be useful to give some variation to a single material assigned to multiple instances, either manually controlled through the object index, based on the object location, or randomized for each instance. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Object_Info --- source/blender/nodes/CMakeLists.txt | 1 + source/blender/nodes/NOD_shader.h | 1 + .../nodes/shader/nodes/node_shader_object_info.c | 61 ++++++++++++++++++++++ 3 files changed, 63 insertions(+) create mode 100644 source/blender/nodes/shader/nodes/node_shader_object_info.c (limited to 'source/blender/nodes') diff --git a/source/blender/nodes/CMakeLists.txt b/source/blender/nodes/CMakeLists.txt index 772ce376cb8..f7e0fd57ff6 100644 --- a/source/blender/nodes/CMakeLists.txt +++ b/source/blender/nodes/CMakeLists.txt @@ -158,6 +158,7 @@ set(SRC shader/nodes/node_shader_volume_isotropic.c shader/nodes/node_shader_light_path.c shader/nodes/node_shader_light_falloff.c + shader/nodes/node_shader_object_info.c shader/nodes/node_shader_mix_shader.c shader/nodes/node_shader_add_shader.c shader/nodes/node_shader_output_lamp.c diff --git a/source/blender/nodes/NOD_shader.h b/source/blender/nodes/NOD_shader.h index 3d93f41cfe5..dd6d25380b4 100644 --- a/source/blender/nodes/NOD_shader.h +++ b/source/blender/nodes/NOD_shader.h @@ -74,6 +74,7 @@ void register_node_type_sh_attribute(struct bNodeTreeType *ttype); void register_node_type_sh_geometry(struct bNodeTreeType *ttype); void register_node_type_sh_light_path(struct bNodeTreeType *ttype); void register_node_type_sh_light_falloff(struct bNodeTreeType *ttype); +void register_node_type_sh_object_info(struct bNodeTreeType *ttype); void register_node_type_sh_fresnel(struct bNodeTreeType *ttype); void register_node_type_sh_layer_weight(struct bNodeTreeType *ttype); void register_node_type_sh_tex_coord(struct bNodeTreeType *ttype); diff --git a/source/blender/nodes/shader/nodes/node_shader_object_info.c b/source/blender/nodes/shader/nodes/node_shader_object_info.c new file mode 100644 index 00000000000..ee356dbb3b3 --- /dev/null +++ b/source/blender/nodes/shader/nodes/node_shader_object_info.c @@ -0,0 +1,61 @@ +/* + * ***** 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.
