Struct ColorBuf 

pub struct ColorBuf { /* private fields */ }

Implements Accumulate for RGB(A) color with f32 components, and conversion to Rgba.

In addition to its use in constructing images, this type is also used as an intermediate format for surface colors presented to any other Accumulate implementation.

Implementations

impl ColorBuf

pub fn opacity_category(self) -> OpacityCategory

Returns the opacity of the contents of this buffer.

Trait Implementations

impl Accumulate for ColorBuf

type BlockData = ()

Data precomputed for each distinct block or other type of visible object.

fn opaque(&self) -> bool

Returns whether self has recorded an opaque surface and therefore will not be affected by future calls to Self::add.

fn add(&mut self, hit: Hit<'_, <ColorBuf as Accumulate>::BlockData>)

Adds the light from a surface or volume, and its opacity, to the accumulator. This surface is positioned behind/beyond all previous add()ed surfaces.

fn mean<const N: usize>(items: [ColorBuf; N]) -> ColorBuf

Combine multiple completed buffers into one, such as multiple samples for antialiasing.

fn enter_block(&mut self, block_data: &Self::BlockData)

Called before the ray traverses any surfaces found in a block; that is, before all add() calls pertaining to that block.

fn paint( color: Rgba, options: RtOptionsRef<'_, <Self::BlockData as RtBlockData>::Options>, ) -> Self

where Self: Sized + Default,

Creates an accumulator already containing the given color.

impl Clone for ColorBuf

fn clone(&self) -> ColorBuf

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ColorBuf

impl Debug for ColorBuf

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

Formats the value using the given formatter.

impl Default for ColorBuf

fn default() -> ColorBuf

Returns the “default value” for a type.

impl From<Rgba> for ColorBuf

fn from(value: Rgba) -> ColorBuf

Converts the given Rgba color value, interpreted as the reflectance and opacity of a surface lit by white light with luminance 1.0, into a ColorBuf.

impl PartialEq for ColorBuf

fn eq(&self, other: &ColorBuf) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
