Usage ¶
getAttributeUInt8DataAsync(session: hapi.Session, node_id: int, part_id: int, name: str, attr_info: hapi.AttributeInfo, stride: int, start: int, length: int) → (list of HAPI_UInt8, int)
Get attribute unsigned 8-bit integer data asynchronously.
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 node id.
part_id
The part id.
name
Attribute name.
attr_info
hapi.AttributeInfo used as input for what tuple size. you want. Also contains some sanity checks like data type. Generally should be the same struct returned by hapi.getAttributeInfo.
stride
Specifies how many items to skip over for each element. With a stride of -1, the stride will be set to attr_info->tuple_size. Otherwise, the stride will be set to the maximum of attr_info->tuple_size and stride.
start
First index of range. Must be at least 0 and at most hapi.AttributeInfo.count - 1.
length
Must be at least 0 and at most
hapi.AttributeInfo.count - start.
Note, if 0 is passed for length, the function will just
do nothing and return hapi.result.Success.
Returns a tuple of (data_array, job_id).
