trimesh.parent¶
parent.py¶
The base class for Trimesh, PointCloud, and Scene objects
Classes:

Helper class that provides a standard way to create an ABC using inheritance. 

Geometry is the parent class for all geometry. 
The Geometry3D object is the parent object of geometry objects which are three dimensional, including Trimesh, PointCloud, and Scene objects.

Geometry
¶ Bases:
abc.ABC
Geometry is the parent class for all geometry.
By decorating a method with abc.abstractmethod it just means the objects that inherit from Geometry MUST implement those methods.
Methods:
apply_scale
(scaling)Scale the mesh.
apply_transform
(matrix)apply_translation
(translation)Translate the current mesh.

class
trimesh.parent.
Geometry3D
¶ Bases:
trimesh.parent.Geometry
The Geometry3D object is the parent object of geometry objects which are three dimensional, including Trimesh, PointCloud, and Scene objects.
Methods:
Apply the oriented bounding box transform to the current mesh.
Attributes:
An axis aligned bounding box for the current mesh.
An oriented bounding box for the current mesh.
A minimum volume bounding cylinder for the current mesh.
The minimum volume primitive (box, sphere, or cylinder) that bounds the mesh.
A minimum volume bounding sphere for the current mesh.

apply_obb
()¶ Apply the oriented bounding box transform to the current mesh.
This will result in a mesh with an AABB centered at the origin and the same dimensions as the OBB.
 Returns
matrix – Transformation matrix that was applied to mesh to move it into OBB frame
 Return type
(4, 4) float

property
bounding_box
¶ An axis aligned bounding box for the current mesh.
 Returns
aabb – Box object with transform and extents defined representing the axis aligned bounding box of the mesh
 Return type

property
bounding_box_oriented
¶ An oriented bounding box for the current mesh.
 Returns
obb – Box object with transform and extents defined representing the minimum volume oriented bounding box of the mesh
 Return type

property
bounding_cylinder
¶ A minimum volume bounding cylinder for the current mesh.
 Returns
mincyl – Cylinder primitive containing current mesh
 Return type

property
bounding_primitive
¶ The minimum volume primitive (box, sphere, or cylinder) that bounds the mesh.
 Returns
bounding_primitive – Smallest primitive which bounds the mesh: trimesh.primitives.Sphere trimesh.primitives.Box trimesh.primitives.Cylinder
 Return type
object

property
bounding_sphere
¶ A minimum volume bounding sphere for the current mesh.
Note that the Sphere primitive returned has an unpadded exact sphere_radius so while the distance of every vertex of the current mesh from sphere_center will be less than sphere_radius, the faceted sphere primitive may not contain every vertex.
 Returns
minball – Sphere primitive containing current mesh
 Return type
