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

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
