Struct Material 

pub struct Material {
    pub id: String,
    pub density: Option<f64>,
}

Material stamped on a Terminal by a Mat("...") grammar op.

Carries an asset identifier (used by downstream renderers to look up textures / shaders) and an optional mass density in kg/m³ used to derive MassProperties for physics, LOD, and IK pipelines.

Fields

id: String

Identifier the renderer uses to resolve textures / shaders.

density: Option<f64>

Mass density in kg/m³. When Some, the interpreter computes MassProperties for every terminal stamped with this material. When None, the terminal’s Terminal::mass_properties stays None.

Implementations

impl Material

pub fn new(id: impl Into<String>) -> Self

Creates a material with no density (purely a renderer-side identifier).

pub fn with_density(id: impl Into<String>, density: f64) -> Self

Creates a material with a mass density in kg/m³.
