Detailed Description

Functions for working with attributes.

Function Documentation

HAPI_DECL HAPI_AddAttribute	(	const HAPI_Session *	session,
		HAPI_NodeId	node_id,
		HAPI_PartId	part_id,
		const char *	name,
		const HAPI_AttributeInfo *	attr_info
	)

Add an attribute.

Parameters

[in]	session	The session of Houdini you are interacting with. See HAPI_Sessions for more on sessions. Pass NULL to just use the default in-process session.
[in]	node_id	The SOP node id.
[in]	part_id	Currently not used. Just pass 0.
[in]	name	Attribute name.
[in]	attr_info	HAPI_AttributeInfo stores attribute properties.

HAPI_DECL HAPI_DeleteAttribute	(	const HAPI_Session *	session,
		HAPI_NodeId	node_id,
		HAPI_PartId	part_id,
		const char *	name,
		const HAPI_AttributeInfo *	attr_info
	)

Delete an attribute from an input geo.

Parameters

[in]	session	The session of Houdini you are interacting with. See HAPI_Sessions for more on sessions. Pass NULL to just use the default in-process session.
[in]	node_id	The SOP node id.
[in]	part_id	Currently not used. Just pass 0.
[in]	name	Attribute name.
[in]	attr_info	HAPI_AttributeInfo stores attribute properties.

HAPI_DECL HAPI_GetAttributeDictionaryArrayData	(	const HAPI_Session *	session,
		HAPI_NodeId	node_id,
		HAPI_PartId	part_id,
		const char *	name,
		HAPI_AttributeInfo *	attr_info,
		HAPI_StringHandle *	data_fixed_array,
		int	data_fixed_length,
		int *	sizes_fixed_array,
		int	start,
		int	sizes_fixed_length
	)

Get array attribute dictionary data. Each entry in an array attribute can have varying array lengths. Therefore the array values are returned as a flat array, with another sizes array containing the lengths of each array entry.

Dictionary data is serialized as JSON-encoded strings. Note that the string handles returned are only valid until the next time this function is called.

Parameters

[in]	session	The session of Houdini you are interacting with. See HAPI_Sessions for more on sessions. Pass NULL to just use the default in-process session.
[in]	node_id	The node id.
[in]	part_id	The part id.
[in]	name	Attribute name.
[in]	attr_info	HAPI_AttributeInfo used as input for the. totalArrayElements. Also contains some sanity checks like data type. Generally should be the same struct returned by HAPI_GetAttributeInfo().
[out]	data_fixed_array	An HAPI_StringHandle array at least the size of HAPI_AttributeInfo::totalArrayElements.
[in]	data_fixed_length	Must be HAPI_AttributeInfo::totalArrayElements.
[out]	sizes_fixed_array	An integer array at least the size of sizes_fixed_length to hold the size of each entry.
[in]	start	First index of range. Must be at least 0 and at most HAPI_AttributeInfo::count - 1.
[in]	sizes_fixed_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.

Warning

The string handles should be used to retrieve the strings immediately and are invalidated when another call to get this attribute's data is made.

[in]	session	The session of Houdini you are interacting with. See HAPI_Sessions for more on sessions. Pass NULL to just use the default in-process session.
[in]	node_id	The node id.
[in]	part_id	The part id.
[in]	owner	The HAPI_AttributeOwner enum value specifying the owner of the attribute.
[out]	attribute_names_array	Array of ints (string handles) to house the attribute names. Should be exactly the size of the appropriate attribute owner type count in HAPI_PartInfo.

Set unsigned 8-bit attribute integer data.

Parameters

[in]	session	The session of Houdini you are interacting with. See HAPI_Sessions for more on sessions. Pass NULL to just use the default in-process session.
[in]	node_id	The SOP node id.
[in]	part_id	Currently not used. Just pass 0.
[in]	name	Attribute name.
[in]	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().
[in]	data_array	An unsigned 8-bit integer array at least the size of length * HAPI_AttributeInfo::tupleSize.
[in]	start	First index of range. Must be at least 0 and at most HAPI_AttributeInfo::count - 1.
[in]	length	Must be at least 0 and at most HAPI_AttributeInfo::count - start.
