[dfelinto]

Attending: Dalai Felinto, Hans Goudey, Jacques Lucke, Pablo Vazquez, Simon Thommes.

Agenda:

• Sprint planning

Sprint Planning

Jacques won’t attend Wednesday (15/Apr) meeting.

Goal: Curves and initial volume support in preparation to upcoming projects. Also leaving room to see if there are any pressing bugs reported as part of the Beta.

• Remaining 2.93 tasks
  • Create Workspace for Geometry Nodes
  • Join Node remaining issues
  • Spreadsheet tasks (rule filter, hide/reveal columns)
  • User Interface for attribute search
• Sprites Fright features
  • T87421: Attribute Transfer Node initial version
    • Further details in design task: T86843
• Curves initial support
  • Curves to Mesh node
  • Curves to Point node
  • Point attributes for curves
  • Curve “geometry nodes” modifier
• Volume “geometry nodes” modifier

Note, other tasks were left for the module contributors to help, such as spreadsheet navtree.

Design Discussions

Week starting 2021-04-12

Monday

• Can we close D4960: New Voxel Mesher Modifier? (Hans)
  • This should be implemented in geometry nodes rather than as a modifier
  • • Hans will close it.
• Basic design sign-off for
  • T87315: Convex Hull Node (Hans)
    • Output name → Geometry. Hans will follow up
  • D10951: A Mesh Smooth node, as designed in T86903.
    • Perfect. Hans will follow up
• D10931 Node context pinning (Jacques)
  • Breadcrumbs
    • Ob > Node
    • Ob > Modifier > Node Group > Node Group > Node Group > Node (ellipsis) [full path on tooltip]
  • Toggling behaviour and how it changes other editors.

Tuesday

• Present final Point/Vertex domain proposal (Dalai).
  • Accepted.
• Proposal for active modifier visualization change (Hans)
  • The poposals are (arguably) an improvement but they are also far from ideal, so it’s hard to get excited about them.
  • We talk about it on thursday again.
• 14:30 CEST Wrapping up attribute and texture painting design.

Thursday

• I/O and instancing (Dalai)
  • I want to present to the team the currently challenges Andy is facing when exporting Geometry Nodes to USD.
  • Not much a design section, but more food for thought.
• Proposal for active modifier visualization change (Hans)
  • The extra icon in the header is far from ideal
  • A way to highlight the panel under the cursor could be a bit better

Friday

• Mode presentation

Week starting 2021-04-19

Monday

• Curves use case presentation: Procedural modeling with curves

Tuesday

• Spreadsheet
  • Single column lable for vec2, vec3 and color components (centralized).
  • This can be for 2.93.
  • Try using .x, .y, .z for row filtering.
• 14:30 to 15:30: Use case Meetings for the modes HQ

Wednesday

• Show warning in Attribute Transfer node?
  • Might be enough to not show any attributes in the source attribute name dropdown.
  • Always showing (and printing) a warning in the default state could be quite annoying.

Thursday

• Present use cases from Tuesday (Dalai).

Friday

• Erindale’s feedback on procedural modeling.
• Validate the row filtering design
• Retrospective

Note: This will be updated throughout the next two weeks with the day to day design discussions.

Next planning meeting: 2021-04-26 at 14:00 CEST on geometry-nodes on blender.chat.
