Delete Branch "casey-bianco-davis/blender:GPv3-Curve-Geometry-Overlay"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
This is for rendered geometry and does not apply for edit mode overlays.
Note: This is hard to test without #122966
Sorry if this is dumb question, but when recently Bezier drawing and editing was implemented for Curves type I thought it was for grease pencil too? Don't they share CurvesGeometry?
They do share
CurvesGeometry
but the evaluated geometry was not being sent to the GPU, nor the triangulation; that's what this PR does.@ -314,3 +314,3 @@

It's important to avoid allocating a separate array for points if there are only poly curves in the drawing.
For that I suggest passing the array as a reference argument and returning a VArray that either references the original or the newly allocated and filled array.

This change is unrelated, best to just leave it out. Personally I choose to increment variables on separate lines just so the order is more obvious at a glance.
Code looks good to me. Nice that this is such a small change.
I'm getting some memory leaks when I tried this out:
@casey-bianco-davis anything you wouldn't expect here?
With this change, loading files from GPv2 that used curve editng with bezier curves look correct now :)
I could not get memory errors to occur.
@filedescriptor The log you got appears to be mentioning code unrelated to this PR, but as I cannot replicate the error I am not sure.
