From bf47fb40fd6f0ee9386e9936cf213a1049c55b61 Mon Sep 17 00:00:00 2001 From: Jacques Lucke Date: Thu, 9 Sep 2021 12:54:20 +0200 Subject: Geometry Nodes: fields and anonymous attributes This implements the initial core framework for fields and anonymous attributes (also see T91274). The new functionality is hidden behind the "Geometry Nodes Fields" feature flag. When enabled in the user preferences, the following new nodes become available: `Position`, `Index`, `Normal`, `Set Position` and `Attribute Capture`. Socket inspection has not been updated to work with fields yet. Besides these changes at the user level, this patch contains the ground work for: * building and evaluating fields at run-time (`FN_fields.hh`) and * creating and accessing anonymous attributes on geometry (`BKE_anonymous_attribute.h`). For evaluating fields we use a new so called multi-function procedure (`FN_multi_function_procedure.hh`). It allows composing multi-functions in arbitrary ways and supports efficient evaluation as is required by fields. See `FN_multi_function_procedure.hh` for more details on how this evaluation mechanism can be used. A new `AttributeIDRef` has been added which allows handling named and anonymous attributes in the same way in many places. Hans and I worked on this patch together.
