Struct MeshFaceColorQuantity 

pub struct MeshFaceColorQuantity { /* private fields */ }

A face color quantity on a surface mesh.

Implementations

impl MeshFaceColorQuantity

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

Creates a new face color quantity (RGB, alpha defaults to 1.0).

pub fn new_with_alpha( name: impl Into<String>, structure_name: impl Into<String>, colors: Vec<Vec4>, ) -> Self

Creates a new face color quantity with explicit RGBA alpha values.

pub fn colors(&self) -> &[Vec4]

Returns the colors.

pub fn has_transparency(&self) -> bool

Returns true if any color has alpha < 1.0.

pub fn compute_vertex_colors( &self, faces: &[Vec<u32>], num_vertices: usize, ) -> Vec<Vec4>

Computes vertex colors by expanding face colors to all vertices of each face. For each vertex, uses the color of the last face it belongs to.

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

Builds the egui UI for this quantity.
