Agenda & Notes

Meeting Notes

Show all commits
  • Grease Pencil: New Fill Tool Algorithm
    • Casey has been making more progress on the new fill tool.
    • It’s now an option in the exiting tool called Exact (final name to be determined).
    • It handles holes and can also do inverted fill.
    • Try it out (download link in the PR)!
  • Grease Pencil: Draw Tool: Add option to create cyclic stroke
    • Option should not be by itself in the Stroke panel.
    • Could be next to the cap types in the tool bar?
      • Others disagree.
    • Casey: Thinks it belongs in the Advanced panel. Ideally this could be toggled with a modifier key while drawing.
    • Falk: Would be good to get more feedback on this from other artists on how they would use it.
  • Samuel: Could we get a setting in the draw tool to set the corner type (especially for when using the new Curve Type option)?
    • Falk: Currently, we don’t detect corners in the draw tool when converting the curve type. This is something we should add in the future. When this gets added, we can also add a corner type setting in the same PR.
  • Samuel: Would it make sense to have a new cap type thats a triangle?
    • Not sure how useful this is.
    • Current workaround is to add another point at the end with small (or zero) radius.
  • Geometry Nodes: Expose Grease Pencil Operators #157297
    • Quakers has been proposing new nodes for Grease Pencil exposing some of the built-in operators.
    • Set Stroke Type looks good!
    • Set Corner Type could use an input for the limit angle when setting the sharp corners.
    • Set Cap Shape should probably be named Set Cap Type for consistency. Makes sense otherwise.
    • Transform Texture
      • The Stroke mode should also expose the Translation (called offset) and Rotation (which is the per point uv rotation).
      • Casey: The Fill mode should have a way to select the coordinate space (Object/Stroke).
      • The inputs should be 2D vectors for the translation and scale.
    • Simplify Stroke
      • Falk: Some of these can be implemented into a (built-in) node group asset using a selection + delete points. E.g. the Fixed mode is a selection of every nth-point. The Adaptive mode could instead be a new selection input node to select points that are on a straight line (based on a threshold).
      • Falk: The Sample and Merge option should be generic curve nodes.

That sounds like something a node group should handle IMO.

This is about an attribute that controls the rendering of the strokes corner. See https://projects.blender.org/blender/blender/pulls/143688. I’m not sure what the node group would do that you have in mind?

Oh, I thought that was referring a node group input that would be used as a selection when writing attributes.
