Struct Material 

pub struct Material {
    pub alpha: u8,
    pub mode: BlendMode,
}

One material: an opacity and a blend mode, indexed out of a MaterialTable by a per-voxel material id.

Fields

alpha: u8

Opacity for BlendMode::AlphaBlend / intensity scale for BlendMode::Additive; ignored for BlendMode::Opaque. 0 = fully transparent, 255 = fully opaque / full intensity.

mode: BlendMode

How the voxel composites with what is behind it.

Implementations

impl Material

pub const OPAQUE: Material

The reserved, fully-opaque material at table id 0 — the back-compat default for every voxel without explicit material data.

pub fn alpha_blend(alpha: u8) -> Material

An BlendMode::AlphaBlend material with opacity alpha.

pub fn additive(alpha: u8) -> Material

An BlendMode::Additive glow material scaled by alpha.

pub fn volumetric(alpha: u8) -> Material

A BlendMode::Volumetric (Beer–Lambert) material whose alpha is the per-voxel-unit absorption — opacity accrues with the ray’s path length through filled volumes (smoke/fog/murky water).

pub fn is_opaque(self) -> bool

True for BlendMode::Opaque — the first-hit, fully-occluding path.

Trait Implementations

impl Clone for Material

fn clone(&self) -> Material

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Material

impl Debug for Material

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

Formats the value using the given formatter.

impl Default for Material

fn default() -> Material

Returns the “default value” for a type.

impl Eq for Material

impl PartialEq for Material

fn eq(&self, other: &Material) -> 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.
