Structure

Grease Pencil object has three main basic components: points, edit lines and strokes.

Example of Grease Pencil structure.

Points

The main element used in editing Grease Pencil objects are points. Points represent a single point in 3D space.

Each point stores all the properties that define the final appearance of the strokes as its location, thickness, alpha, weight and UV rotation for textures.

Obs

Point (Grease Pencil) and Vertex (meshes) are equivalent names.

Edit Lines

Points are always connected by a straight line, which you see when you are editing in Edit Mode or when you look at a stroke in wireframe view. They are invisible on the rendered image and are used to construct the final stroke.

Strokes

The stroke is the rendered image of the points and edit lines, using a particular Grease Pencil material. (Grease Pencil materials are linked at stroke level.)
