Snap support for Grease Pencil objects
Confirmed, NormalPublicTO DO

Description

Description

Big picture: Make it possible for the snap options: Vertices, Edges and Face, to work on Grease Pencil objects

Use cases:

  • Precisely positioning a Grease Pencil object on a Mesh in the 3DView
  • More flexibility in positioning the 3D Cursor

Design:

  • Will work in conjunction with 3DView's snap system (no new interface required)

Engineer plan:

  • Since Grease Pencil objects can be 3D, a BVHTree system may have to be implemented to snap to faces and occlusion test.
  • Another option is to work with a depth buffer.
