HAPI_DECL HAPI_CreateHeightFieldInput	(	const HAPI_Session *	session,
		HAPI_NodeId	parent_node_id,
		const char *	name,
		int	xsize,
		int	ysize,
		float	voxelsize,
		HAPI_HeightFieldSampling	sampling,
		HAPI_NodeId *	heightfield_node_id,

	)

Creates the required node hierarchy needed for heightfield inputs.

Note that when saving the Houdini scene using HAPI_SaveHIPFile() the nodes created with this method will be green and will start with the name "input".

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]	parent_node_id	The parent node network's node id or -1 if the parent network is the manager (top-level) node. In that case, the manager must be identified by the table name in the operator_name.
[in]	name	Give this input node a name for easy debugging. The node's parent OBJ node and the Null SOP node will both get this given name with "input_" prepended. You can also pass NULL in which case the name will be "input#" where # is some number.
[in]	xsize	size of the heightfield in X
[in]	ysize	size of the heightfield in y
[in]	voxelsize	Size of the voxel
[in]	sampling	Type of sampling which should be either center or corner.
[out]	heightfield_node_id	Newly created node id for the heightfield node. Use HAPI_GetNodeInfo() to get more information about the node.
[out]	height_node_id	Newly created node id for the height volume. Use HAPI_GetNodeInfo() to get more information about the node.
[out]	mask_node_id	Newly created node id for the mask volume. Use HAPI_GetNodeInfo() to get more information about the node.
[out]	merge_node_id	Newly created merge node id. The merge node can be used to connect additional input masks. Use HAPI_GetNodeInfo() to get more information about the node.

HAPI_DECL HAPI_CreateHeightfieldInputVolumeNode	(	const HAPI_Session *	session,
		HAPI_NodeId	parent_node_id,
		HAPI_NodeId *	new_node_id,
		const char *	name,
		int	xsize,
		int	ysize,
		float	voxelsize
	)

Creates a volume input node that can be used with Heightfields.

Note that when saving the Houdini scene using HAPI_SaveHIPFile() the nodes created with this method will be green and will start with the name "input".

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]	parent_node_id	The parent node network's node id or -1 if the parent network is the manager (top-level) node. In that case, the manager must be identified by the table name in the operator_name.
[out]	new_node_id	Newly created node id for the volume. Use HAPI_GetNodeInfo() to get more information about the node.
[in]	name	The name of the volume to create. You can also pass NULL in which case the name will be "input#" where # is some number.
[in]	xsize	size of the heightfield in X
[in]	ysize	size of the heightfield in y
[in]	voxelsize	Size of the voxel
