CreateSerializedRequestMessage()

std::string open3d::io::rpc::CreateSerializedRequestMessage

(

const std::string &

msg_id

)

Creates a serialized Request message for testing purposes.

	)

Sets the object with the specified path as the active camera.

Parameters

path	Path descriptor defining a location in the scene tree. E.g., 'mygroup/mycam'.
connection	The connection object used for sending the data. If nullptr a default connection object will be used.

SetLegacyCamera()

bool open3d::io::rpc::SetLegacyCamera	(	const camera::PinholeCameraParameters &	camera,
		const std::string &	path = "",
		int	time = 0,
		const std::string &	layer = "",
		std::shared_ptr< ConnectionBase >	connection = std::shared_ptr< ConnectionBase >()
	)

Function for sending Camera data.

Parameters

camera	The PinholeCameraParameters object.
path	Path descriptor defining a location in the scene tree. E.g., 'mygroup/mycam'.
time	The time point associated with the object.
layer	The layer for this object.
connection	The connection object used for sending the data. If nullptr a default connection object will be used.

SetMeshData()

bool open3d::io::rpc::SetMeshData	(	const core::Tensor &	vertices,
		const std::string &	path = "",
		int	time = 0,
		const std::string &	layer = "",
		const std::map< std::string, core::Tensor > &	vertex_attributes = std::map< std::string, core::Tensor >(),
		const core::Tensor &	faces = core::Tensor({0}, core::Dtype::Int32),
		const std::map< std::string, core::Tensor > &	face_attributes = std::map< std::string, core::Tensor >(),
		const core::Tensor &	lines = core::Tensor({0}, core::Dtype::Int32),
		const std::map< std::string, core::Tensor > &	line_attributes = std::map< std::string, core::Tensor >(),
		const std::map< std::string, core::Tensor > &	textures = std::map< std::string, core::Tensor >(),
		std::shared_ptr< ConnectionBase >	connection = std::shared_ptr< ConnectionBase >()
	)

Function for sending general mesh data.

Parameters

vertices	Tensor with vertices of shape [N,3]
path	Path descriptor defining a location in the scene tree. E.g., 'mygroup/mypoints'.
time	The time point associated with the object.
layer	The layer for this object.
vertex_attributes	Map with Tensors storing vertex attributes. The first dim of each attribute must match the number of vertices.
faces	Tensor with vertex indices defining the faces. The Tensor is of rank 1 or 2. A rank 2 Tensor with shape [num_faces,n] defines num_faces n-gons. If the rank is 1 then polys of different lengths are stored sequentially. Each polygon is stored as a sequence 'n i1 i2 ... in' with n>=3. The type of the array must be int32_t or int64_t
face_attributes	Map with Tensors storing face attributes. The first dim of each attribute must match the number of faces.
lines	Tensor with vertex indices defining the lines. The Tensor is of rank 1 or 2. A rank 2 Tensor with shape [num_lines,n] defines num_lines linestrips. If the rank is 1 then linestrips of different lengths are stored sequentially. Each linestrips is stored as a sequence 'n i1 i2 ... in' with n>=2. The type of the array must be int32_t or int64_t
line_attributes	Map with Tensors storing line attributes. The first dim of each attribute must match the number of lines.
textures	Map of Tensors for storing textures.
connection	The connection object used for sending the data. If nullptr a default connection object will be used.

SetPointCloud()

bool open3d::io::rpc::SetPointCloud	(	const geometry::PointCloud &	pcd,
		const std::string &	path = "",
		int	time = 0,
		const std::string &	layer = "",
		std::shared_ptr< ConnectionBase >	connection = std::shared_ptr< ConnectionBase >()
	)

Function for sending a PointCloud.

Parameters

pcd	The PointCloud object.
path	Path descriptor defining a location in the scene tree. E.g., 'mygroup/mypoints'.
time	The time point associated with the object.
layer	The layer for this object.
connection	The connection object used for sending the data. If nullptr a default connection object will be used.

SetTime()

bool open3d::io::rpc::SetTime	(	int	time,
		std::shared_ptr< ConnectionBase >	connection = std::shared_ptr< ConnectionBase >()
	)

Sets the time in the external visualizer.

Parameters

time	The time value
connection	The connection object used for sending the data. If nullptr a default connection object will be used.

SetTriangleMesh()

bool open3d::io::rpc::SetTriangleMesh	(	const geometry::TriangleMesh &	mesh,
		const std::string &	path = "",
		int	time = 0,
		const std::string &	layer = "",
		std::shared_ptr< ConnectionBase >	connection = std::shared_ptr< ConnectionBase >()
	)

Function for sending a TriangleMesh.

Parameters

pcd	The TriangleMesh object.
path	Path descriptor defining a location in the scene tree. E.g., 'mygroup/mypoints'.
time	The time point associated with the object.
layer	The layer for this object.

UnpackStatusFromReply()

std::shared_ptr< messages::Status > open3d::io::rpc::UnpackStatusFromReply	(	const zmq::message_t &	msg,
		size_t &	offset,
		bool &	ok
	)

Helper function for unpacking the Status message from a reply.

Parameters

msg	The message that contains the Reply and the Status messages.
offset	Byte offset into the message. Defines where to start parsing the message. The offset will be updated and will point to the first byte after the parse messages. If unpacking fails offset will be set to the end of the message.

Returns

The extracted Status message object. Check

Parameters

ok	to see if the returned object is valid.
