November 21 - November 27

This week I started working on simulations, worked on bug fixing, and moved the rest of the interface directory to C++.

I got the simulation input and output nodes to a point where they worked in my very basic tests, but it turned out the branch was actually stable enough for people to do some really cool testing, we saw a lot of that this week. It's been motivating, but the next step of the project is harder.

My first test with the simulation branch was a bit boring! Luckily others made some more interesting things.

Next Week

The Blender conference! So, preparing for giving part of a talk about geometry nodes, and lots of other stuff. Hopefully I can find time to commit the add menu patch too, Julian has figured out dynamic menu redrawing in the last week.

October 9 - October 14

This week I worked on some performance improvements: bounding boxes, draw module data extraction, and BMesh to mesh conversion. I also worked a bit more on the node assets menu patch.

Hopefully I'll get to the point of committing the node editor add menu asset integration. Other than that, I'd like to make progress on some of the changes with bounding boxes, and I also started some experimental changes to mesh data extraction for drawing that I'd like to finish.

Next Week

I'll try to finish getting node group assets in the add menu, and I'll probably work more on the sample curve node, do more code review, and work more on various mesh data refactors.

September 19 - September 25

This week I committed a bunch of changes for 3.4 and did some code review and bug fixing. It was nice to commit some of the mesh refactor patches that have been around for a while. I worked on a few mesh topology access nodes too.

An initial set of topology access nodes for geometry nodes, aimed at 3.4. Since we don't have lists, we have to sort the connected elements in some cases and retrieve a specific index in the sorted values.

I also made these two design tasks:

• T101313: Add a selection input to the store named attribute node
• T101312: Splitting the "Object Info" node, access to object original geometry

Changes / Features

Next Week

I'll look into a bunch of high priority bugs that have come up recently, and work on adding assets to the node add menus.

September 12 - September 18

This week I looked into making sculpt mode hiding more consistent and found a couple other performance improvements there.

The result of splitting the "Transfer Attribute" node into three separate nodes.

I also converted the last curve node to the new data-block. I could finally remove the old curve implementation. 8 months later or so!

Next Week

Next week I'll try to finish some of the patches I've created recently, and hopefully commit the node editor assets in search menu patch. I'd also like to make progress on the mesh topology input nodes.

September 5 - September 11

This week I worked more on mesh data structure refactors, cleaning up the node editor, fixing bugs, and code review. I committed one change I've been working on for a couple months, removing custom data pointer usage from Mesh. It was great to finish that.

August 8 - August 28

The past few weeks I've been traveling and haven't been working full-time, so I gathered them all here. The work I've done has mostly been cleanups and refactors, and some code review. The mesh data structure refactors have come a long way though.

Next Week

Determine 3.4 priorities, update patches, code review, and finishing the "assets in search menu" patch.

Next Week

Probably more of the same. I'll be taking some time off at the end of the week though.

July 25 - July 31

This week I worked on some bug fixing, code review, and did the initial patch for adding node group assets to the node editor. I made a few design tasks as well:

• T99996: Remove object-linked materials
• T100010: Splitting the "Attribute Transfer" node
• T100004: Add an "Exists" boolean to the named attribute input node

One bug that took a while to investigate was a problem with mesh sculpt mode where normals weren't calculated and normalized properly on the boundaries between inconsistently tagged PBVH nodes. The fix ended up being nice in the end though.

The file from T96810 with the artifacts from the improper normals on the boundaries between PBVH nodes where vertices are shared.

Next Week

Probably mostly bug fixing, but hopefully making progress on various refactors: the custom data pointer removal, the add menu, and the field contexts.

July 4 - July 10

This week the main focus was moving the new curves object out of experimental. We had to make some compromises to do that in time for 3.3 (realistically there isn't that much we can still fit into that release), but I think the result is still pretty nice. Some other nice things like the refactored attribute API and the curves sculpt mode selection overlay landed this week too. I also joined the sculpt module meeting to talk about operators to store and load masks/selections as attributes.

I looked into adding support for the curves sculpt selection in the spreadsheet filter. It was relatively simple, actually.

Lately I've been focusing on finishing up existing smaller projects. I updated my two current mesh data structure refactors (D14077 and D14685), updated my design about how to deal with volume grids as attributes, sifted through all the char * members in DNA, and did some more cleanup.

Next Week

I think I'll be able to finish porting almost every node to the new type next week. Maybe some other things will come up though.

June 13 - June 19

This week was a bit light in terms of time, and I didn't accomplish too much. But I did get a fair amount of cleanup done, mostly in attribute extraction in the draw module. I'm happy with that change anyway.

I figured out some of the boilerplate for drawing the sculpt selection for curves, nothing visual yet though.

I also made a design task for a "Field on Domain" building block node: T98943

Changes / Features

Next Week

Next week I'll be back in the US. Apart from taking some time to get things settled there, I'll be working on basically the same things I suppose, maybe with a bit of "geometry nodes as an operator" sprinkled in. But the main goal is still getting selection drawing figured out.

June 6 - June 10

This was my last week in Amsterdam. I mostly spend time on code review, moving some nodes to the new curves type, and preparing a presentation about the current state of the hair project, which should become a blog post relatively soon. I also did some fixing and cleanup in the attribute C API.

Next Week

Next week I'll be visiting Berlin. I'll also try to make progress on the curves sculpt selection drawing task.

May 30 - June 6

This week was full of lots of code review, cleanup, and bug fixes. We also had a geometry nodes sub-module meeting on Wednesday (meeting notes here), and had design discussions about curves sculpt mode, and some initial discussions about how we should progress with the development of simulations.

I also committed the curves sculpt mode selection patch I've been working on for a bit and worked a bit more on porting nodes to the new curves type.

I was also involved in various design tasks, including one about enum names, more conversation about my mesh SoA refactor, and another about various socket and node names. I also closed the task for the "mesh screw node", and created two tasks:

• T98533: Writing to 8 bit integer "enum" attributes in geometry nodes

Next Week

Next week I'll try to get the selection drawing for curves working as an overlay. Since I don't know how much work that will be I won't plan too much more besides the usual bug fixing and code review.

May 16 - May 22

This week I started by doing a bunch of documentation/manual work from the backlog, mainly for 3.2 features: rBM9284, rBM9285

I also focused on finishing up the selection brush and related tools for curves sculpt mode. It should be mainly ready here: D14934. We also spent time discussing/planning/reviewing render engine support for the curves data-block: T96455.

Other than that, I spent time on bug fixing, plenty of planning, and some miscellaneous work on curves sculpt mode.

Next Week

Next week is mostly vacation for me, I'm taking the time to explore the Amsterdam area.

May 9 - May 15

This week I did general work in the curves/hair area, especially the sculpt mode. The main thing I finished was some UI changes I did some work adjusting the UI layouts in the brush header and tool settings, but I also mostly finished a patch to add selection and masking (which at this point is mostly missing drawing in the viewport). We also made some progress on that front by solidifying the plan for drawing the old hair particle system with the new curves object.

We also ran into some design difficulties with how to attach curves to the surface mesh, but I think the result of that will end up in a simpler system actually.

The layout doesn't fit in the tool header

We can use specialized popovers for a specific brush type to make the UI more organized.

The start of a tool to paint a selection in sculpt mode, using a design where the selection is painted, rather than the opposite

Next Week

I'll port more curve nodes to the new data-block, do more code review, and maybe some continued struct-of-array refactoring for mesh code.

March 28 - April 3

This week I finished the patches for converting nodes to the new data structure that I started last week.

I spent a lot of time on code review, mainly for the sculpt colors patch and two Alembic import patches, but also for a fair amount of smaller changes.

I also made a design task for improvements to bounding boxes (T96968) that should be relevant to instancing performance improvements (T92963). And another code architecture topic I looked into a bit was curve evaluation on the GPU (T96455). It looks like it's important that GPU evaluation is implemented for performance in the viewport.

Adding attribute search that changes the node's output type and the links properly based on what you click.

Next Week

I'll have to spend some time solving the current issue with curve object updates (T96498). Beyond that, next week will probably look pretty similar.

March 21 - March 27

This week I spent most of my time working on porting more nodes to the new curve data structure, and on bug fixes. The performance improvements I get when porting nodes are satisfying, and it's really important to make sure we don't have three separate curve types in Blender's code, but I'm getting a bit burnt out working on constant refactoring, so I might take a break from that next.

Next Week

Bug fixing and code review (though I guess that goes without saying by now). I'll finish up the node conversions I started last week, but I may start working on updating the drawing code next week.

March 14 - March 20

This week I committed the first curves evaluation and used in a few nodes, and also ported plenty more nodes to the new data structure. Some of the conversions unlocked a lot of performance. I observed a 150x improvement in the duplicate elements node, as a nice example.

I did some miscellaneous code review. Not that much bug fixing though, I'll have to catch up on that next week.

Also, I removed the code for the old legacy geometry nodes from before 3.0. A ~13000 line reduction! That means fewer areas to refactor to the new curves type.

February 21 - February 27

Another very similar week! I worked a bit on the conversion of the curve geometry component, splitting off some initial changes to master.

Next Week

More similar work: curves evalaluation, and a bit of code review and bug fixing.

February 14 - February 18

Another very similar week, only a couple things really different from last week. On Friday Jacques and I discovered a threading issue with the new lazy normal calculation that I had to fix: T95839

Part of the work on the curve data structure sent me on a tangent of reworking the newly added C++ templated math operations to add support for basic types like float and int, in addition to the vector types like float3. That's useful for sharing very type-agnostic code.

Similar plan: I'll do a bit more bug fixing for 3.1, work on curves evaluation and the refactor to change nodes to the new data structure, and do code review.

February 7 - February 13

This week I worked more on implementing the curves data-block, lots of miscellaneous code review, some bug fixes, and had some meetings.

Next Week

The same as last week's plan: code review and a bit of work for 3.2 targets, continue building the new curves data structure, and bug fixing.

January 31 - February 6

This week I mainly worked on bug fixing, code review, and starting to refactor the new curves data structure.

I also organized a 3.2 targets list for geometry nodes, and created tasks where necessary. There were some design discussions about 2D vector sockets, which I suppose I'll continue next week.

One interesting bug I ran into was T93245, where it turns out that creating over 2047 instances overrides point cloud object's color!

Next Week

I plan to basically continue the same things, code review for 3.2 targets, continue building the new curves data structure, and bug fixing.

January 24 - January 30

This was a bit of a duller week. I finished up the necessary manual pages for all of the new geometry nodes features in 3.1, and worked on bug fixing. Plus a little bit of code review. There were no daily meetings since Jacques was in Amsterdam.

Next Week

I'll probably spend a fair amount of time working on bug fixes, and hopefully start refactoring the curves data structure. I also wanted to make a proposal about how to improve caching of object bounding boxes in the code.

January 17 - January 23

This week my main goal was finishing up the extrude node, which I thankfully did finish. I also worked on lots of other relatively random things that came up, including some bug fixes, code review, and cleanup (like usual), and updated the Nodes & Physics module page to fit in with the new organization.

All of the new code should be quite well tested at this point. Many of the tests deal with attribute interpolation, which is probably the more complicated aspect of the node.

I ported the weld modifier to the merge by distance node, hopefully we can get that into 3.1.

Next Week

Just bug fixing and work on the manual for all the new 3.1 features. I'll try to get the merge by distance node into 3.1 as well, and on Monday I'll start by moving my extrude node test file to become regression tests.

January 10 - January 14

This week the most exciting thing is that I landed the vertex normal refactor I've been working on. Apart from some issues with an OBJ test that I hadn't tested since it was added, it went well I think, though I do see a couple of bug reports now. I did some performance testing, and it made some observable gains in real files, which was a nice surprise, since I was mostly approaching it from the "understandable code" perspective.

We had some longer meetings talking about patches and other design topics this week. The meeting notes are pretty lengthy here: https://devtalk.blender.org/t/2022-1-10-2022-01-14-geometry-nodes-sub-module-meetings/22405

I spent quite a while reviewing a patch that exposes color painting in sculpt mode (previously "sculpt vertex colors") in master, and had a bit of a discussion about it afterwards.

Next Week

Now that I've had a break and some time to think about it, I'll come back to the "extrude regions" case for the extrude node. Then some code review, and hopefully merge by distance for meshes (looking into porting the weld modifier again).

January 3 - January 9

This week I didn't really finish anything notable. Mostly it was a big time vacuum with lots of work on various branches and discussions about "random" things like GPU acceleration, performance bottlenecks, and patches.

Next Week

I want to finish the larger things that I think could actually make it to 3.1: the extrude node, the mesh normals refactor, and the merge by distance node. Beyond that, I'll plan patch review and bug fixing, but I think I'll be realistic and keep it at that.

December 27 - January 3

This was a relatively relaxed week, with not many people around. Besides bug fixing and code review, I mainly worked on a mesh extrude node. I'm almost done with that, and happy with how it's turning out.

The work-in-progress extrude node in individual face mode, showing the transfer of the material index attribute, with the vertex mode on the right.
