When drawing in a 3d space with grease pencil, is there a way to fill a curved / endless plane. for example, If I draw a rectangle, with 2 square corners on one end and a radius on the other. And then Duplicate and drag over. is it possible to fill The gap between the 2 grease pencil objects? I have not yet found if this is possible.
(1) First we have to get all the individual polygon (face) vertices using Mesh Object Node and Separate Polygons Node. Separate Polygons Node is needed because all polygons are joined i.e., they are sharing some vertices,
(2) then convert a polygon vertices to a close (cyclic) grease pencil stroke with fill using GPencil Stroke Output Node.
(3) Because a mesh has many polygons (faces) so we are going to use the Loop Group Node (Loop Input) to convert all polygons to fill grease pencil strokes (cyclic).
(4) Now we have all strokes as output from the Loop Node, with GPencil Object Output Node we can convert them to a grease pencil object.
