Struct MeshFaceVectorQuantity 

pub struct MeshFaceVectorQuantity { /* private fields */ }

A face vector quantity on a surface mesh.

Implementations

impl MeshFaceVectorQuantity

pub fn new( name: impl Into<String>, structure_name: impl Into<String>, vectors: Vec<Vec3>, ) -> Self

Creates a new face vector quantity.

pub fn vectors(&self) -> &[Vec3]

Returns the vectors.

pub fn length_scale(&self) -> f32

Gets the length scale.

pub fn set_length_scale(&mut self, scale: f32)

Sets the length scale.

pub fn radius(&self) -> f32

Gets the radius.

pub fn set_radius(&mut self, r: f32)

Sets the radius.

pub fn color(&self) -> Vec4

Gets the color.

pub fn set_color(&mut self, c: Vec3)

Sets the color.

pub fn auto_scale(&mut self, structure_length_scale: f32)

Auto-scales length and radius based on the structure’s bounding box diagonal and the average vector magnitude, so arrows are proportionally visible.

Target: effective arrow length ≈ 2% of bbox diagonal, radius = 1/10 of length.

pub fn init_gpu_resources( &mut self, device: &Device, bind_group_layout: &BindGroupLayout, camera_buffer: &Buffer, base_positions: &[Vec3], )

Initializes GPU resources for this vector quantity.

pub fn render_data(&self) -> Option<&VectorRenderData>

Returns the render data if initialized.

pub fn update_uniforms(&self, queue: &Queue, model: &Mat4)

Updates GPU uniforms with the given model transform.

pub fn build_egui_ui(&mut self, ui: &mut Ui) -> bool

Builds the egui UI for this quantity.
