Next Week

More of the same mostly I suppose. I'm mainly using this in between time to try to fill in some gaps and make future work easier.

December 4 - December 10

This week I did a fair amount more performance and cleanup work in the sculpt module. I'm trying to approach it from both ends: improving existing code iteratively and planning some larger replacements like the rewritten brushes (starting with the draw brush in Sergey's branch). So far for the larger changes I'm focusing on operator code where I can more easily measure performance changes.

I also:

  • Made a bit of progress on curves custom normals calculation. Though I didn't finish it like I hoped.
  • Added matrix sockets and a custom data type in a branch. Besides the mixing, that's basically done.
  • Fixed a performance regression from quadratic performance in BMesh data copying. Funny to see something deep in my todo list raised to high priority with a report. A lesson in trusting my instincts maybe.

  • Mesh: Avoid calculating corner normals for drawing flat-shaded meshes c4446d7924
  • BMesh: Optimize copying attributes from many elements at once 0b1049b41d

Next Week

I'll make a PR for basic curves custom normals support, make a design for matrix sockets, and continue some sculpt refactoring.

November 13 - November 26

The DDoS attack made it hard to make last week's report, so this is a combination of the last two weeks.

Lots of stuff finished recently! The main thing I'm happy about is getting the number of branches on my repo from around 40 to 23. That means I have far fewer WIP projects, which is helpful for my sanity. I'm looking forward to getting that number even lower.

Apart from the commits listed below, I also worked on the start of a sculpt brush refactor with Sergey. We're trying to make the implementation of the draw brush nicer to start, then move on to other brushes and multires, and dynamic topology. The main difficulty is still measuring performance reliably though. It's hard to commit to a few key decisions without that.

This week was mainly spent discussing geometry nodes design in a workshop with Dalai, me, Jacques, Simon, and Lukas. I'm pretty happy with the results. We agreed on a direction for lots of important topics (except there's more discussion that needs to happen about appended-asset deduplication). There's a blog post about it here.

Next Week

Jacques will be here at the HQ, so we'll go through a bunch of design topics. And I still have a couple more things to fix for 4.0.

October 16 - October 22

This was a busy week!

  • I worked with Sergey on the next portion of the dynamic topology project, getting edge attribute interpolation working so we can maintain boundaries. Though I didn't have as much time for that as I would have hoped. I did get to do some cleanups to sculpt mode in general though.
  • I helped to review and design the grease pencil integration with geometry nodes.
  • I finished the face map changes for 4.0, including a change to versioning and a new operator to select elements based on a boolean attribute.
  • I worked on the slides for my conference presentation, though I still have a bit to do there.
  • And then, as always, various code reviews and bug fixes.
  • I landed the auto smooth conversion to geometry nodes, the idea being that it should land early in 4.1.
  • I tested an implementation of an index switch node which would support switching between an arbitrary number of items, like a dumb version of the menu switch.
  • I made progress on the bounding box refactors. That's another big one, but it's a nice simplification so far!

Next Week

I'll mostly be doing things related to the conference, but also trying to fix some remaining bugs for 4.0.

October 9 - October 15

This week I helped with the geometry nodes grease pencil support that a few others are working on, did some work in geometry nodes, and otherwise spent my time in sculpt mode, including fixes, cleanup, and code review for dynamit topology features.

Sergey and I talked about face maps for a while and made a plan to lessen the "breaking" aspects of the removal in 4.0. I regret forgetting about that for a while earlier, the situation would be much simpler if I had added a feature or two early on in the 4.0 process.

I also made a video with Pablo about node tools. It was pretty fun to share that project more publicly.

Next Week

I'd like to spend more time on sculpt mode, work on my Blender conference talk, and spend time on some geometry nodes topics.

October 2 - October 8

This week I arrived in Amsterdam, so super busy, but fewer commits since there were a lot of in person discussions. Sergey and I worked out a plan to start getting dynamic topology improved in smaller incremental steps, where each step is a more obvious improvement.

We also talked a fair amount about how volumes should work in geometry nodes, and I helped look into some developments for grease pencil, especially the integration with geometry nodes.

I worked on default field inputs to allow building node groups that act more like builtin nodes. That's necessary for this "Random Rotation" node group.

Next week I'm traveling to Amsterdam for six weeks! Besides that, I'm also planning to resolve a few limitations for node tools, and do some more work on ongoing projects.


September 18 - September 24

I'd mainly like to finish the to-dos for node tools.

September 4 - September 10

This week I worked on updating the modifier interface, the auto smooth replacement task (I had a meeting with Campbell and Bastien where we agreed to move it to 4.1), and some node tools tasks.

Other than that I started a rewrite of the triangulate node to use Mesh instead of BMesh. That's nearly finished except for the "Beauty" mode for quads which is surprisingly complicated.

Next Week

I'll mainly work on some node tools things but also spend a bit of time on the auto smooth node group task to make some progress on the todos here.


August 28 - September 3

This week I landed a bunch of mesh changes I had been working on for a while, I worked more on the auto smooth port to geometry nodes, and did a bunch of code review. Towards the end of the week I worked on changes to the modifier UI in order to make the auto smooth change work better.

I worked on integrating geometry node group assets with the add modifier menu. That will be really important as custom modifiers are used more and more.
I also worked on a design for remaking the modifier stack into a list. My work here is coming full circle to how my contracted work started years ago! I think this is pretty elegant, especially as the single-modifier workflow is used more for the more complex things.

Next Week

I'd really like to commit the auto smooth to geometry node group conversion, including the changes to the modifier add menu. I assume I'll spend time resolving some node tools limitations, and maybe doing more cleanup in sculpt mode code too.

August 21 - August 27

This week I mainly focused on mesh normals, with the goal of finishing the conversion of auto smooth to a geometry nodes modifier. I made a design task for an asset to replace auto smooth, called "Smooth by Angle". I also met with Pablo where we discussed asset integration to modifiers and a more general UI overhaul there. We also discussed a reorganizing the compositor add menu.

As part of the work on rotation nodes, I made a design task about a Swap Node Operator meant to be a proper implementation of the feature node wrangler had for a while.

Siggraph next week!

July 17 - July 23

This week I was mostly stalled on my main project the node group operators, but in the meantime I looked into some performance improvements for sculpt mode, focussing on decreasing the time to switch from object mode to sculpt mode. I also updated some patches for normals and worked more on rewriting the edge split node. Some meetings and related discussions about node tools took a fair amount of time too.

I renamed some mesh data and make a follow-up task about renaming "loops" too:

Next Week

I'd really like to get my existing node group operators patches landed.

July 10 - July 15

This week I mainly worked on bug fixes, node group operators, code review, and started adding support for face domain color attributes (in vertex paint and sculpt mode). One bug with the split edges node took a LOT of time and I'm not quite done with it yet. I'm much happier with the state of the code now though; it's a bit longer but easier to follow and doesn't have any intermediate states anymore.

Two new design tasks this week:

I have to respond to some valid points on the second one. I think it's probably not worth splitting up the color separate/combine nodes. I still think the math nodes are worth separating though, eventually.

Next Week

I'll be on vacation.


July 3 - July 9

This week I mainly worked on node group operators. I also did some code review-- mainly a PR to import and export generic attributes for USD, which is pretty exciting! I also worked on a few performance improvements in some random areas, and renamed Mesh "polys" to "faces" (in a PR for now).

Inputs are working for node group operators, though there are still a couple limitations.

The basics of the design for more object types for the operators is coming together. We won't use tags, but a more specialized UI in the node editor. That helps make things a bit easier to learn and a bit faster. You still have to open the asset browser to add the asset to a catalog though.

An initial UI for editing asset traits, to control how an operator can be used.

Next Week

More of the same, but also I'll implement face domain color attribute painting, because otherwise the USD color attribute import will have to become weirder and more complex.

June 26 - July 2

This week I worked on node group operators and made a prototype for a button in the modifier interface to switch modes for editing attributes.

I'm finding the node tools stuff pretty exciting. The possibility of letting geometry nodes work better interactively is really cool. The possibilities are endless, and the idea makes Blender much more easily customizeable and scalable.

A first set of nodes that are only available when geometry nodes is run as a tool/operator.

Next Week

More work on node group operators, and hopefully moving forward with rotation nodes. Maybe we'll decide more solidly on the "switch context" button so I can work more on that too.

June 19 - June 23

This week I spent most of my time fixing bugs for 3.6. It took a while but I finally have no more high priority reports assigned to me. I also worked on a few larger projects:

  • Mesh Normals and Auto Smooth in 4.0 #93551
  • Node group operators initial phase PR #108947

Rotation nodes are held up because we didn't agree yet about whether to have more than one node or combine a bunch of operations into some "Combine/Separate Rotation" node.

Next Week

I'd like to move on to the next phase of node group operators, and get some agreement about rotation nodes.

June 12 - June 18

This week I worked on node group operators and rotation sockets. The basics of both are working now.

Dynamic menus built from the asset catalogs of node group operators. I'd like to add point cloud edit mode, and use it as experiment of a node group only mode, that could be really cool.
Some initial rotaiton socket nodes, mostly just for separating and combining at this point.

I also worked on some mesh cleanups and moved more code to C++. And did a bunch of code review.

Next Week

I'll post a design task about mesh normals, update the initial node group operators patch, and work more on rotation sockets.


May 30 - June 4

This week I worked on the delete geometry node, code review, splitting out a small change from the node group operators branch, and on rotation sockets. I also did code review and looked into fixing some high priority bugs I caused in the last few weeks. Monday was a holiday here, and I was moving to a new appartment later in the week, so I wasn't able to work full days.

Next Week

I'd like to finish rotation sockets and the first iteration of node group operators, and fix more of the high priority bugs.

May 23 - May 28

A 4.5 day week here-- I took most of Monday off. I spent a fair amount of time this week unifying things after the index mask refactor landed, which gave some nice improvements to the delete geometry node (I'm also looking at simplifying that for meshes locally). Besides that, I looked into bugs, did some code review, kept some PRs up to date, and spent a bit of time with the node group operators branch (kept getting distracted from that though!)

I'd like to split some changes from the node group operators branch and make it a bit more generic so it's not just for curves. Besides that, I'd like to make progress on rotation sockets and the auto smooth replacement.

Next Week

Hopefully I can finish some of the things I started this week, and maybe make some progress on node group operators.

May 8 - May 14

This week I finished adding some more features to simulation nodes-- making caching optional and subframe mixing, and worked more on mesh topology caching. I refactored the existing topology maps to all use the same implementation, and added a few cached maps to Mesh. The tricky part there is figuring out which topology maps to cache, all of them would be way too much, but only one or two seem to miss some significant performance improvement opportunities. Both of the changes are still in review but I hope I can make more progress next week.

Next Week

The rest of the team is having a workshop on node group operators and node tools. I'm not sure how much I'll be able to participate remotely, so I might have to find something else that can occupy a fair amount of time. I think that might be rotation sockets, or more work on my branch that replaces mesh auto smooth (for 4.0).


May 1 - May 7

A 4 day week, I took Friday off.

We committed the simulation nodes branch! I did a bunch of cleanup there to get it into a mergeable state, and helped implement a couple of the remaining features. I also finished some performance improvements to face corner normal calculation with custom normals, just reducing memory usage and doing things like using indices instead of pointers.

Suzanne is spinning about twice as fast as a few versions ago, in this test file from Brad Clark.

After simulations landed, I started implementing a cache toggle for simulation nodes so it could work more efficiently in a realtime context that isn't concerned with the cache. I also started working on simulation subframe mixing, but stopped when I didn't understand the context or the big picture of why it would work the way I was doing it. I'll have to look into that again next week.

Next Week

I hope to finish adding the cache checkbox early on Monday or Tuesday. Beyond that it depends on the team's priorities I think, not sure where we'll head right now. I might look into caching mesh topology maps again too.

April 24 - April 30

This week I helped to finish parts of the simulation branch, including moving some of the changes to main. I did some bug fixing, and looked into mesh face corner normal calculation again. I've mostly been looking at it from the perspective of reducing memory usage, which has been enough for a 50% improvement so far at least, I'd say. I also looked into the performance of the new Index of Nearest node a bit.

Next Week

Hopefully we can merge the simulation branch. Beyond that, I hope to just get closer to finishing a bunch of the things I've been working on, no particular focus yet.


April 17 - April 23

This week I finally finished the mesh struct of arrays refactor I started a year and a half ago (#95965). A big project! But not really bigger than I expected, I actually sort of expected it to take longer. I learned a lot in the process. And the benefits can still trickle into other places, but with the file-format impacting changes over with, there's no urgency.

I tried to help with some of the simulation nodes changes, taking some of the tangentially related topics and finishing them up for main. I did plenty of code review too, mainly for simulation things. And we spent some time discussing the baking UI (#107181).

Along with that I committed a cache for loose vertices, aiming to make viewport drawing of large geometry-nodes-generated meshes faster.

Next Week

I plan to do more bug fixing and help with merging the simulation nodes branch (late for Bcon1 unfortunately).

April 11 - April 16

This week I worked on implicit sharing for mesh and curve offsets, a few random mesh related improvements, and made progress with node group operators. I started to look into how to register the input properties, but didn't make much progress after that. I ended up being very busy with bug fixing recently. That figures considering the large changes I've been making across mesh stuff though. I also did some cleanups to the geometry nodes simulation branch.

Next Week

Next week I'll hopefully have more visible results for node group operators, and I'll fix a bunch of the bugs that have been piling up.


March 27 - April 1

This week I fixed bugs, worked on mesh optimizations including a 4-6x improvement in time for extracting mesh data for Cycles and some improvements for skipping calculation of loose edges and vertices for rendering.

Next Week

More node group operators work and more bug fixing.

March 20 - March 26

This week I worked on landing the final mesh struct-of-array refactors (two still to land, but everything is finished), more bug fixing for 3.5, and helped with some final manual updates for 3.5 (not sure how to link those on my weekly report though).

I also worked on a slightly longer-term improvement to Mesh normals calculation that I also mentioned last week, PR #105920. This week I did some performance testing. Long story short, it's going to need some more work, at least for the final goal of proper determinism.

I helped Jacques with the refactor to IndexMask from PR #104629 by replacing a trivial implementation of the function to convert a bit mask to an IndexMask with something that should take advantage of the new design. It still needs a bit of work though.

Next Week

Actually final commits to 3.5 if necessary, and I'll try to work on node group operators and help on simulation where I can.

March 13 - March 19

This week I worked on the simulation nodes branch (mainly 3bad7a51cb), finishing my mesh refactoring, and some final bug fixing for 3.5.

Next Week

I'll have to take a couple days off I think, but I hope to be nearly done with the mesh refactoring, and make some more progress on simulation nodes, and hopefully start some work on node group operators.

March 6 - March 12

This week was a bit slower because of nodes and physics workshop going on in Amsterdam. I still found things to work on though-- bug fixes, performance improvements, the subtype selector for node group inputs/outputs, mesh refactors, and of course code review. So I think it was actually a productive week!

I also added the first infrastructure for multiple inputs and outputs to the simulation nodes branch.

I worked on caching for loose vertices too (PR #105567), but there are two definitions of "loose vertices" and both are used:

  • Vertices not connected to any faces (may be used by loose edges)
  • Vertices not connected to any edges

Maybe caching both would be fine, it's only a bitmap anyway. But I'll put that one on hold for now.

Next Week

I'd like to keep making progress on the two remaining mesh refactors, and work o node operators, or maybe simulation nodes.

February 27 - March 5

This week I mainly focused on mesh cleanups, with the goal of making my two remaining large patches (corners and faces refactors) simpler. I want them to look more like "find and replace" than complex changes, since the diffs are massive.

I also did the regular code review and bug fixing as things came up. I also made some design tasks for planned breaking changes in 4.0:

  • #105316 Particle system removal for 4.0

Next Week

Next week I'll hopefully get closer to finishing the mesh changes, and maybe start on node group operators if the design is a bit more settled. I'll also probably take part in some design discussions happening at the HQ, at least a bit.


February 20 - February 23

Next Week

Same thing as last week basically!


January 23 - February 5

Combined the last two weeks since some unexpected personal stuff came up and I had to travel a bit. Besides a bit of distraction (probably only really did a week of work or so) I still got some things done, though mostly unplanned things and a bit more simple work like refactors and triaging than usual.

I made two new tasks also, two interesting (IMO) performance topics. I've made a fair amount of progress on the first, I'm down to 83 uses of MPoly now from over 1000 before. Still a ways from getting the branch to compile though (refactor-mesh-face-generic for those curious).

Next Week

I have quite a few high priority reports stacked up so I'll really have to start with those. Then there's some code review I can get to, and the remainder of my most recent to-do list looks like this:

  • Duplicate entries in node search for assets with local ID
  • Grab curves sculpt brush
  • Root ID use in shaders for randomization
  • Field status toggle
  • Subtype editing

January 16 - January 22

This week I worked on various fixes, performance improvements, smaller new features, code review, and updating some existing patches. I also moved 50 files to C++, in preparation for another mesh data structure refactor. This time I'd like to replace MPoly with offset indices like we did for curves. There's no need to store the size of a polygon when it can be calculated from the next offset integer in the array. Storing the size is like caching the result of a subtraction, which doesn't really make sense. Jacques also added a nice abstraction for that this week, the OffsetIndices class, which I used in more places.

I still have two high priority bugs to look into, but I was able to close a few this week.
