trimesh.parent#
parent.py#
The base class for Trimesh, PointCloud, and Scene objects
- class trimesh.parent.Geometry#
Bases:
ABC
Geometry is the parent class for all geometry.
By decorating a method with abc.abstractmethod it means the objects that inherit from Geometry MUST implement those methods.
- apply_scale(scaling)#
Scale the mesh.
- Parameters:
scaling (float or (3,) float) – Scale factor to apply to the mesh
- abstract apply_transform(matrix)#
- apply_translation(translation)#
Translate the current mesh.
- Parameters:
translation ((3,) float) – Translation in XYZ
- abstract property bounds#
- abstract copy()#
- abstract export(file_obj, file_type=None)#
- abstract property extents#
- abstract is_empty() bool #
- abstract show()#
- class trimesh.parent.Geometry3D#
Bases:
Geometry
The Geometry3D object is the parent object of geometry objects which are three dimensional, including Trimesh, PointCloud, and Scene objects.
- apply_obb(**kwargs)#
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.
- Parameters:
kwargs – Passed through to bounds.oriented_bounds
- 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:
