Utilities for working with the Universal Scene Description (USD) format.

Functions

convert_warp_type(v)	Determine the Warp type, e.g. wp.quat, wp.vec3, or wp.float32, from a USD value.
convert_warp_value(v[, warp_dtype])	Convert a USD value (such as Gf.Quat, Gf.Vec3, or float) to a Warp value.
get_attribute()	Get an attribute value from a USD prim, returning a default if not found.
get_attributes_in_namespace(prim, namespace)	Get all attributes in a namespace from a USD prim.
get_custom_attribute_declarations(prim)	Get custom attribute declarations from a USD prim, typically from a PhysicsScene prim.
get_custom_attribute_values(prim, ...)	Get custom attribute values from a USD prim and a set of known custom attributes.
get_float()	Get a float attribute value from a USD prim, validating that it's finite.
get_gprim_axis(prim[, name, default])	Get an axis attribute from a USD prim and convert it to an Axis enum.
get_mesh(prim[, load_normals, load_uvs, ...])	Load a triangle mesh from a USD prim that has the UsdGeom.Mesh schema.
get_quat()	Get a quaternion attribute value from a USD prim, validating that it's finite and non-zero.
get_scale(prim)	Extract the scale component from a USD prim's local transformation.
get_transform(prim[, local, invert_rotation])	Extract the transform (position and rotation) from a USD Xform prim.
has_attribute(prim, name)	Check if a USD prim has a valid and authored attribute.
