OBJ

class compas.files.OBJ(filepath, precision=None)[source]

Bases: object

Read and write files in OBJ format.

Currently, reading is only supported for polygonal geometry. Writing is only supported for meshes.

Examples

Reading and writing of a single mesh.

from compas.datastructures import Mesh
from compas.files import OBJ

mesh = Mesh.from_polyhedron(12)

# write to file
obj = OBJ('mesh.obj')
obj.write(mesh)

# read from file
obj = OBJ('mesh.obj')
obj.read()

mesh = Mesh.from_vertices_and_faces(obj.vertices, obj.faces)

Reading and writing of multiple meshes as separate objects in a single OBJ file.

from compas.geometry import Pointcloud, Translation
from compas.datastructures import Mesh
from compas.files import OBJ

meshes = []
for point in Pointcloud.from_bounds(10, 10, 10, 100):
    mesh = Mesh.from_polyhedron(12)
    mesh.transform(Translation.from_vector(point))
    meshes.append(mesh)

# write to file
obj = OBJ('meshes.obj')
obj.write(meshes)

# read from file
obj = OBJ('meshes.obj')
obj.read()

meshes = []
for name in obj.objects:
    mesh = Mesh.from_vertices_and_faces(* obj.objects[name])
    mesh.name = name
    meshes.append(mesh)
