POLYDATA message for 3D polygon/mesh data

OpenIGTLink Specification

• Message type: “POLYDATA”
• Format: Points + Vertices + Lines + Polygons + Triangle Strips + Attributes
• Complex variable-length structure

Fields

points: Vec<[f32; 3]>

3D points (x, y, z)

vertices: Vec<u32>

Vertex indices

lines: Vec<u32>

Line connectivity (first element = count, followed by indices)

polygons: Vec<u32>

Polygon connectivity (first element = count, followed by indices)

triangle_strips: Vec<u32>

Triangle strip connectivity

attributes: Vec<Attribute>

Attribute data

Implementations

impl PolyDataMessage

pub fn new(points: Vec<[f32; 3]>) -> Self

Create a new POLYDATA message

pub fn with_vertices(self, vertices: Vec<u32>) -> Self

Add vertices

pub fn with_lines(self, lines: Vec<u32>) -> Self

Add lines

pub fn with_polygons(self, polygons: Vec<u32>) -> Self

Add polygons

pub fn with_triangle_strips(self, strips: Vec<u32>) -> Self

Add triangle strips

pub fn add_attribute(&mut self, attr: Attribute)

Add attribute

pub fn num_points(&self) -> usize

Get number of points

Trait Implementations

impl Clone for PolyDataMessage

fn clone(&self) -> PolyDataMessage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PolyDataMessage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Message for PolyDataMessage

fn message_type() -> &'static str

Returns the message type name (e.g., “TRANSFORM”, “IMAGE”)

fn encode_content(&self) -> Result<Vec<u8>>

Encode message content to bytes

fn decode_content(data: &[u8]) -> Result<Self>

Decode message content from bytes

impl PartialEq for PolyDataMessage

fn eq(&self, other: &PolyDataMessage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
