compas-plotter 1.0.0

2D visualisation of COMPAS geometry and data structures with matplotlib.

COMPAS Plotter

2D visualisation of COMPAS geometry and data structures, powered by matplotlib.

compas_plotter provides a lightweight, dependency-free (other than matplotlib) way to draw COMPAS objects in 2D. It is the COMPAS 2.x successor of the compas_plotters package that shipped inside COMPAS up to version 1.17, rebuilt on top of the modern compas.scene system. It registers a "Plotter" visualisation context, so any COMPAS object with a registered plotter scene object can be drawn with a single plotter.add(...).

Installation

pip install compas_plotter

Quick start

from compas.geometry import Point, Line, Polygon
from compas.datastructures import Mesh
from compas_plotter import Plotter

plotter = Plotter(figsize=(8, 5))

mesh = Mesh.from_polyhedron(8)
plotter.add(mesh, show_vertices=True, show_edges=True)
plotter.add(Polygon([[0, 0, 0], [3, 0, 0], [3, 3, 0]]), facecolor=(0.9, 0.9, 1.0))
plotter.add(Line(Point(0, 0, 0), Point(3, 3, 0)), linecolor=(1, 0, 0))
plotter.add(Point(1.5, 1.5, 0))

plotter.zoom_extents()
plotter.show()

Supported objects

Category	Objects
Geometry	Point, Vector, Line, Polyline, Polygon, Circle, Ellipse, Frame
Shapes (drawn as XY projections)	Box, Sphere, Cylinder, Cone, Capsule, Torus, Polyhedron
Data structures	Mesh, Graph

Brep, Surface, NurbsCurve, VolMesh and Plane are not yet supported — see the roadmap.

Roadmap

Planned additions, most likely drawn as XY projections following the existing ShapeObject:

• Brep and Surface (tessellate to a mesh, then project; Brep needs an optional backend such as compas_occ)
• NurbsCurve (sampled to a polyline)
• VolMesh and Plane
