Enum AlphaMode 

pub enum AlphaMode {
    Opaque,
    Mask(f32),
    Blend,
}

Controls how the alpha component of albedo is interpreted.

Variants

Opaque

Alpha is ignored; the surface is fully opaque.

Mask(f32)

Pixels whose alpha is below the stored cutoff are discarded (discard in GLSL). The inner f32 is the cutoff threshold in [0, 1].

Blend

Standard alpha blending — the surface is rendered with transparency.

Implementations

impl AlphaMode

pub fn cutoff(self) -> Option<f32>

Returns the alpha cutoff if the mode is Mask, otherwise None.

pub fn needs_sorting(self) -> bool

Returns true when the material requires depth-sorted rendering.

pub fn variant_tag(self) -> &'static str

Returns a short string tag suitable for shader variant selection.

Trait Implementations

impl Clone for AlphaMode

fn clone(&self) -> AlphaMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlphaMode

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

Formats the value using the given formatter.

impl Default for AlphaMode

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for AlphaMode

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

impl Copy for AlphaMode

impl StructuralPartialEq for AlphaMode
