Struct GltfData 

pub struct GltfData {
    pub triangles: BTreeMap<RGBA, Vec<[Vec3; 3]>>,
    pub lines: BTreeMap<RGBA, Vec<[Vec3; 2]>>,
    pub texts: Vec<TextLabel>,
    pub unlit_colors: BTreeSet<RGBA>,
}

Intermediate geometry for glTF export: colored triangles, colored line segments, and text labels, accumulated before serialization to a glTF model.

Fields

triangles: BTreeMap<RGBA, Vec<[Vec3; 3]>>

Filled triangles grouped by color.

lines: BTreeMap<RGBA, Vec<[Vec3; 2]>>

Line segments grouped by color.

texts: Vec<TextLabel>

Positioned text labels.

unlit_colors: BTreeSet<RGBA>

Face colors displayed without diffuse shading, for module ownership.

Implementations

impl GltfData

pub fn scale_face_opacity(&self, scale: f32) -> GltfData

Returns a copy with every triangle color’s alpha multiplied by scale (clamped to opaque). Lines and labels are unchanged.

pub fn pop_faces_at_directions(self, directions: &[Direction]) -> GltfData

Removes filled faces whose outward normal matches one of directions.

Line geometry is retained so the opened graph keeps its silhouette.

pub fn extend(&mut self, other: GltfData)

Merges another data set into this one, combining geometry of matching colors.

pub fn swap_yz(self) -> GltfData

Swaps the y and z axes of all geometry, converting from the graph’s time-up (z) convention to the exporter’s y-up convention.

Triangle winding is flipped to keep front faces oriented after the swap.

pub fn map_points(self, f: impl Fn(Vec3) -> Vec3) -> GltfData

Applies f to every vertex, line endpoint, and text-label position.

Triangle winding is preserved as-is; this does not re-orient normals, so only use it for orientation-preserving transforms such as translations, rotations, and positive scales.

pub fn to_file(&self, path: impl AsRef<Path>) -> Result<(), BlockGraphError>

Writes the scene to a .gltf file.

Vertex colors bake the editor’s diffuse response into unlit materials. Lighting stays fixed; the host viewer does not relight the graph.

Errors

Returns BlockGraphError::Io if the file cannot be written, or BlockGraphError::GltfSerialize if serialization fails.

pub fn to_html_str(&self) -> Result<String, BlockGraphError>

Renders an HTML page with the glTF scene embedded as a base64 data URI.

Vertex colors bake the editor’s diffuse response into unlit materials. Lighting stays fixed; the viewer does not relight the graph. The model-viewer renderer is pulled from a CDN, so the page needs network access to display; the model data itself is inlined.

Errors

Returns BlockGraphError::GltfSerialize if glTF serialization fails.

Trait Implementations

impl Clone for GltfData

fn clone(&self) -> GltfData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GltfData

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

Formats the value using the given formatter.

impl Default for GltfData

fn default() -> GltfData

Returns the “default value” for a type.
