Enum FrameTexture 

#[non_exhaustive]
pub enum FrameTexture {
    SceneDepth,
    SceneColour,
    ShadowMap,
    ScreenSpaceShadows,
    AmbientOcclusion,
    ReflectionProbe,
    LightProbeVolume,
    DecalBuffer(u8),
}

An image of the frame being drawn that a program reads: the consumer supplies it from its own frame, as it supplies a view or frame constant.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SceneDepth

The depth the frame’s depth pass wrote, the hardware depth in x: a program that reads it linearises it with the scene constants’ depth parameters (soft edges of fog, foam and water against the geometry behind).

SceneColour

The colour image of what the frame has drawn so far behind the surface (the opaque scene, or the screen as it stands): what a refracting or see-through surface samples.

ShadowMap

The depth image rendered from a shadow-casting light (the main light’s, its cascades side by side where it has them): a program compares a surface’s depth in that light’s space with it.

ScreenSpaceShadows

The shadow term of the main light gathered per screen pixel: a program samples it at its own screen position, 1 where the light reaches and 0 where it is shadowed.

AmbientOcclusion

The ambient occlusion the frame computed per screen pixel (1 unoccluded).

ReflectionProbe

The cube image of the environment around the surface as the nearest reflection probe, or the sky where there is none, captured: what a reflection samples along the reflected view direction.

LightProbeVolume

The volume image of the light probes’ lighting around the surface (a 3D image of spherical-harmonic coefficients the surface samples at its position).

DecalBuffer(u8)

Image n of the decal buffer the frame’s decal step draws before the surfaces are lit (Unity’s DBuffer: 0 the decals’ albedo, 1 their normal, 2 their metallic, occlusion and smoothness, each with the decals’ coverage in alpha): a lit draw reads it at its own screen position and blends the decals into its surface.

Implementations

impl FrameTexture

pub fn spatial_kind(self) -> SpatialKind

How the frame’s image moves into a program frame.

impl FrameTexture

pub fn dim(self) -> TextureDim

The dimension of the image: a probe’s is a cube, the light probes’ a volume, every other a plane.
