Usage ¶
setGroupMembership(session: hapi.Session, node_id: int, part_id: int, group_type: hapi.groupType, group_name: str, membership_array: list of int, start: int, length: int) → bool
Set group membership.
session
The session of Houdini you are interacting with. See hapi.Session for more on sessions. Pass None to just use the default in-process session.
node_id
The SOP node id.
part_id
Currently not used. Just pass 0.
group_type
The group type.
group_name
The group name.
membership_array
Array of ints that represent the membership of this
group. Should be the size given by
HAPI_PartInfo_GetElementCountByGroupType with
group_type and the hapi.PartInfo of part_id.
start
Start offset into the membership array. Must be less than HAPI_PartInfo_GetElementCountByGroupType.
length
Should be less than or equal to the size
of membership_array. When setting edge group membership,
this parameter should be set to the number of points (which
are used to implictly define the edges), not to the number
edges in the group.
