You can use the bounding box with the Lattice node to create a deformation cage for the input geometry.
Subset of geometry to bound.
The type of elements referenced in the Group field.
Keep the input geometry.
Create When Bounds Empty
If there is no input geometry or the specified group is empty, a zero sized bounding box will be created at the origin. Turning this off will cause an empty geometry to be created instead.
Specifies whether to create a bounding box, sphere, or rectangle.
Oriented Bounding Box (points only)
Orients the bounding box to the axes of the input geometry instead of the world axes.
This algorithm is based on points and so requires primitives with vertex hulls. It will not work with, for example, a primitive sphere or packed geometry. To get the bounding box of a primitive sphere, first convert it to polygons.
Number of divisions for the bounding box, along the xyz axes.
Places diagonal crossbars in the divisions of the box.
Poles of sphere align with orientation axis.
Use a more accurate (but slower) bounding sphere calculation.
Specifies the minimum radius of the bounding sphere.
Oriented Bounding Rectangle
Specifies whether to compute an oriented or axis-aligned bounding rectangle.
Origin of the projection plane used when computing the bounding rectangle.
Distance to translate the bounding rectangle’s projection plane along its normal.
The normal vector of the projection plane for the bounding rectangle.
Lower, Upper Padding
The computed bounding box or sphere is enlarged by these padding values. Note that in the case of spheres, non-uniform padding values will not guarantee the resulting sphere still contains the input geometry.
Output Bounds Group
Toggles whether the Bounds Group is added to the geometry. The Bounds Group can be used to identify primitives in the bounding shape when Keep Original is enabled.
Creates a primitive group with this name, containing the primitives representing the bounding shape.
Output Transform Attribute
Toggles whether the Transform Attribute is added to the geometry.
Creates a detail attribute with this name, containing a 4×4 matrix representing the bounding shape’s translation and rotation. You can this with, for example, Transform By Attribute to apply or reverse the transformation elsewhere.
Output Radii Attribute
Toggles whether the Radii Attribute is added to the geometry.
Creates a detail attribute with this name, describing the extents of the bounding shape. For a sphere this contains the X, Y, and Z radii, and for a bounding box or rectangle this contains the half-length along each axis.
