## Since the Last Meeting
* Performance Improvements.
* Eye dropper for object input in modifier.
* Modifier execution time exposed in Python API.
* (WIP) Overlay for sculpting.
* (WIP) Surface collision.
* (WIP) Output smooth normals from Distribute Points on Faces node.
* (WIP) Bundle assets.
* Simon has been working on finishing the hair node group assets for 3.5
* Jacques worked on a couple of UX improvements
* The modifier no longer shows a warning with multiple geometry inputs ([commit](https://developer.blender.org/rBae80a6696fe))
* Object modifier inputs now have eye-dropper support ([commit](https://developer.blender.org/rB19fe5caf872))
* The menu location of the sample nodes has been tweaked for consistency ([commit](https://developer.blender.org/rB789e549dbae))
* The material from guides is propagated in the Interpolate Curves node ([commit](https://developer.blender.org/rB813425877b6))
* Some performance improvements landed last week
* Curves performance when using cached evaluated data can be much better ([commit](https://developer.blender.org/rB7f958217ada))
* Edit mesh to evaluated mesh conversion has been parallelized ([commit](https://developer.blender.org/rBebe8f8ce719))
* And the duplicate elements node should be a bit faster (more parallel) ([commit](https://developer.blender.org/rB3d6ceb737d8))

## General Discussion
* Falk mentions that he'll continue working on curves edit mode-- mainly selection, and gives a demo of box selection and selection picking.
* Jacques mentions a new node that he added when working on the smooth normals for the distribute points on faces node.
* It's called "Axis to Euler", like "Align Euler to Vector" but faster and simpler.
* The node is technically redundant now already, but is easier to understand and more convenient.
* The node could be replaced with matrix nodes eventually if that ends up being helpful.

## Patch Review & Decision Time

## Next Meeting

The next meeting will be on Tuesday February 21, 15:00-16 CET (Your local time: [date=2023-02-21 time=15:00:00 timezone="Europe/Amsterdam"]), which is 2 weeks from this meeting. The provisional meeting agenda will be linked in the [#geometry-nodes ](https://blender.chat/channel/geometry-nodes) channel before the meeting.
