Jacques Lucke	4599cea15d	Geometry Nodes: refactor instances component ... The main goal of this refactor is to not store Object/Collection pointers for every individual instance. Instead instances now store a handle for the referenced data. The actual Object/Collection pointers are stored in a new `InstanceReference` class. This refactor also allows for some better optimizations further down the line, because one does not have to search through all instances anymore to find what data is instanced. Furthermore, this refactor makes it easier to support instancing `GeometrySet` or any other data that has to be owned by the `InstancesComponent`.

Jacques Lucke	7eb9b7976f	Fix T85889: recursive instances result in crash ... Generally, it would be good to not allow this from happening in the first place but that is quite tricky because an object does not know which other object instances it. Similar checks might be necessary in other places, but this fixes the bug already. Differential Revision: https://developer.blender.org/D11086	2021-04-27 12:33:40 +02:00
Hans Goudey	1e8a808910	Cleanup: Use C++ types in object_dupli.cc ... Using alloca in C++ is not recommended, especially when we have the blender::Array type that can contain an inline buffer.	2021-04-12 16:24:51 -05:00

Hans Goudey	c5d9968392	Cleanup: Remove unecessary part of instances component C API ... Now that object_dupli.cc is a C++ file, we don't have to have a specific function to retrieve the instance data from the geometry set.	2021-04-01 16:23:16 -05:00
Hans Goudey	3ca1cf2b51	Cleanup: Move object_dupli.cc to C++ ... This will hopefully allow more refactoring in the future to improve the instancing system, especially how it relates to geometry nodes instances.	2021-04-01 15:54:48 -05:00
