Development

Animated cartoon loco with particle sim running on the realtime clock

Calendar Week 14

Apr 3 - Apr 9

Calendar Week 15

Apr 10 - Apr 16

Development

  • Copy support for simulation zone nodes #106812
  • Added task to unify copy operators #106852

Code Review

  • Node add searches missing context-based poll #106829
  • Initialize socket value by declaration callback if value is data block #106816

Calendar Week 16

Apr 17 - Apr 23

  • Postponed copy operator unification. Should be supported by python tests and is more work than can be justified atm #106852
  • Finished attribute field type propagation in simulation zones #107133
  • Finished UI for simulation zone items in the node editor #106919
  • Started work on attribute propagation support in simulation zones #107219

Calendar Week 17

Apr 24 - Apr 30

  • Working on baking operators and general cache info panel for simulation nodes #107290
  • Vacation Apr 27 - May 2

Calendar Week 18

May 1 - May 7

  • Moved weekly notes into a yearly subfolder LukasTonne/WeeklyReports/2023
  • Calculate-to-frame operator for setting simulation nodes up to the current frame without baking #107627
  • Fix for crashes due to unsafe simulation node cache access by editors #107621
  • Fix for crash when connecting viewer in a pinned node tree without object context #107737
  • Documenting LOD system in geometry nodes (WIP, further work needed to solve normal continuity)

Calendar Week 19

May 8 - May 14

  • Added support for simulation zones in node group operators (make group, ungroup, insert, separate) #107807
  • Removed versioning code for older geonodes simulation zones #107781
  • Wrote proposal for adding "function socket" as a concept: Node graphs get wrapped as closures, can be passed around node trees, and evaluated at a later stage. This will allow much greater customization of node assets without user having to tweak complex node trees. #107842

Calendar Week 20

May 15 - May 21

  • Mo-We: Workshop for node-based tools and brushes design with Dalai, Jacques, Andy, Simon
  • Working on a prototype for a fracturing system in geometry nodes

Calendar Week 21

May 22 - May 28

  • Fix to prevent creation of unnecessary cache folders (simulation zone exists but is not in use) #108278
  • Add user warning to detect when caches might overwrite existing data on disk #108288
  • Updated Embree test branch and started discussion about benefits and potential issues of replacing Blender's BVH implementation #108148

Calendar Week 22

May 29 - Jun 4

  • Fix for socket shape when copying between different node tree types #108412
  • Sub-panel support for node group socket categories:
 - Add categories to node tree interfaces for organizing large numbers of inputs
 - Support instancing of child panels (remove hidden assumption that child panels are always type-based)
 #108565

Calendar Week 23

Jun 5 - Jun 11

  • Splitting PR for socket sub-panels into manageable pieces:
 - Category declaration in node trees and sockets #108649
 - Return bit arrays as persistent expand flags for panels [8https://projects.blender.org/blender/blender/pulls/108648 #108648]
   _Dropped after changes were postponed until callbacks could support BitVector (c++)_
 - Use instanced child panels to display node socket categories #108565
   _(depends on and includes both PRs above)_
  • Fix for socket display shapes #108412
  • Bug report: assert failure when working within large asset libraries #108703

Calendar Week 24

Jun 12 - Jun 18

  • Panel declaration experimental feature #108649
  • Committed C++ RNA for object, curves, nodes rna-cpp branch

Calendar Week 25

Jun 19 - Jun 25

  • Published preliminary API design for new group interface data structure
  • Discussion on containers, socket/panel ordering, backward compatibility
 #109158
  • Implementing tree view for the new data structure
  • PR for cleaning up color access API of node sockets
 #109288
  • Finished warnings for bake operator when writing to the same directory
 #108263


Calendar Week 26

Jun 26 - 2 Jul

  • After discussion with Brecht, Jacques, and Hans decided to change DNA design of the node group interfaces to a hierarchical structure. Takes a bit longer than anticipated ...
 #109158
  • Review: Serial loop PR by Jacques
 #109164


Calendar Week 27

Jun 3 - 9 Jul

  • Vacation 5-9
  • Working on node socket panels

Calendar Week 28

Jul 10 - 16 Jul

  • Vacation 10-12
  • Working on node socket panels

Calendar Week 29

Jul 17 - Jul 23

  • Still working on node socket panels
 Discussed how forward compatibility can be implemented, settled on doing write-time versioning in 4.0 so older versions have data to read.
 Decided with Brecht to discard the old RNA API to make things easier.
 Todo list: #110272

Calendar Week 30

Jul 24 - Jul 30

Node panels:

  • Implemented backward + forward compatibility for node group interfaces.
  • Deprecated old bNodeTree sockets DNA, RNA
  • Replaced uses of old node group interface.
  • Added custom socket type support for new node group interface items.
  • Discovered that the interface_init_socket API method is no longer used, this may have been an unintended breaking change introduced by node declarations. -> Discussion

Calendar Week 31

Jul 31 - Aug 6

  • Finished most remaining work on socket panels #110272
  • Added python tests for the new node group interfaces
  • Started splitting into parts for easier review, part 1: #110272

Calendar Week 32

Aug 7 - Aug 13

  • Finished and committed part 1/3 of the node socket panels patch #110885
  • Vacation from Aug 10

Calendar Week 33

Aug 14 - Aug 20

  • Vacation until Aug 16
  • Finished and committed part 2/3 of the node socket panels patch #110952

Calendar Week 34

Aug 21 - Aug 27

  • Final part 3/3 of the node socket panels patch in review #111348
 Fixed tests, UI drawing, and other issues found during code review.

Calendar Week 35

Aug 28 - Sep 3

Bug fixes for node panels

Also fixed related issues in Node Wrangler addon caused by breaking API changes

Calendar Week 36

Sep 4 - Sep 10

More bug fixes for node panels

Added a new test to finally have some checks on complicated node versioning.


Calendar Week 37

Sep 11 - Sep 17

More bug fixes for node panels

Support for panels in built-in nodes

Calendar Week 38

Sep 18 - Sep 24

Reverted the "inline sockets" feature after it was decided that this feature would break Blender UI conventions

And some final fixes for node panels
