Used to debug shaders by early exiting the shader and attempting to display the value as shaded colors.

Variants

None = 0

UvCoords0 = 1

Displays the first set of UV coordinates as a color.

UvCoords1 = 2

Displays the second set of UV coordinates as a color.

Normals = 3

Displays normals after normal mapping, in world space

VertexColor = 4

Displays only the vertex color for the fragment.

VertexNormals = 5

Displays vertex normals.

UvNormals = 6

Displays uv normals. These are normals coming from a normal map texture. These are the normals in tangent space.

Tangents = 7

Displays vertex normals.

Bitangents = 8

Displays bitangents as calculated from normals and tangents.

DiffuseIrradiance = 9

Displays only the diffuse irradiance value.

SpecularReflection = 10

Displays only the specular reflection value.

Brdf = 11

Displays only the BRDF value for the fragment.

Albedo = 12

Displays only the albedo color for the fragment.

Roughness = 13

Displays only the roughness value for the fragment.

Metallic = 14

Displays only the metallic value for the fragment.

Occlusion = 15

Displays only the occlusion color for the fragment.

Emissive = 16

Displays only the calculated emissive effect (emissive_tex_color * emissive_factor * emissive_strength) of the fragment.

UvEmissive = 17

Displays only the emissive color (from the emissive map texture) of the fragment.

EmissiveFactor = 18

Displays only teh emissive factor of the fragment.

EmissiveStrength = 19

Displays only the emissive strength of the fragment (KHR_materials_emissive_strength).

Trait Implementations

impl Clone for DebugChannel

fn clone(&self) -> DebugChannel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DebugChannel

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

Formats the value using the given formatter.

impl Default for DebugChannel

fn default() -> DebugChannel

Returns the “default value” for a type.

impl PartialEq for DebugChannel

fn eq(&self, other: &DebugChannel) -> 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 PartialOrd for DebugChannel

fn partial_cmp(&self, other: &DebugChannel) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl SlabItem for DebugChannel

const SLAB_SIZE: usize = 1usize

The number of u32s this type occupies in a slab of &[u32].

fn read_slab(index: usize, slab: &[u32]) -> Self

Read the type out of the slab at index.

fn write_slab(&self, index: usize, slab: &mut [u32]) -> usize

Write the type into the slab at starting index and return the new index.

impl Copy for DebugChannel
