trimesh.parent¶

parent.py¶

The base class for Trimesh, PointCloud, and Scene objects

Classes:

`ABC`()	Helper class that provides a standard way to create an ABC using inheritance.
`Geometry`()	Geometry is the parent class for all geometry.
`Geometry3D`()	The Geometry3D object is the parent object of geometry objects which are three dimensional, including Trimesh, PointCloud, and Scene objects.

class trimesh.parent.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.
`copy`()
`crc`()
`is_empty`()
`md5`()
`show`()

Attributes:

`bounds`
`extents`

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 crc()¶

abstract property extents¶

abstract is_empty()¶

abstract md5()¶

abstract show()¶

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_obb()

Apply the oriented bounding box transform to the current mesh.

Attributes:

`bounding_box`	An axis aligned bounding box for the current mesh.
`bounding_box_oriented`	An oriented bounding box for the current mesh.
`bounding_cylinder`	A minimum volume bounding cylinder for the current mesh.
`bounding_primitive`	The minimum volume primitive (box, sphere, or cylinder) that bounds the mesh.
`bounding_sphere`	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: trimesh.primitives.Box

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: trimesh.primitives.Box

property bounding_cylinder¶

A minimum volume bounding cylinder for the current mesh.

Returns: mincyl – Cylinder primitive containing current mesh
Return type: trimesh.primitives.Cylinder

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: trimesh.primitives.Sphere
