Grease Pencil 3: TODO List

List of things to do:*

12/5/2023
Grease Pencil Rendering Meeting

Is there a good reason for having a separate renderer for Grease Pencil ? Is this to the question “how do we do NPR rendering in Blender” ?

12/4/2023
Grease Pencil Eraser

Go through all the curves and check each segment for intersections with the eraser (circle)

7/10/2023
Grease Pencil Dopesheet Meeting

Mockup of keyframes in Grease Pencil 3.0 GP Keyframes are not a single point in time. They start, are held for 1 or more frames and then end. Is "Keyframe" even the right word? (Static? Block? Discrete?) Cel!Probably needs its own eAnim_KeyType. In general: how do we deal with animation channels that do not have (or cannot be represented by) an FCurve? What about Annotations? Plan is to keep using the current grease pencil data-block (bGPdata). Could be moved to their own Dopesheet maybe?
