Structures

#
Used by 8 shaders
struct PbrInput {
material: PbrTypes,
occlusion: f32,
frag_coord: vec4<f32>,

Functions

prepare_normal

#
Used by 8 shaders

NOTE: This ensures that the world_normal is normalized and if vertex tangents and normal maps then normal mapping may be applied.

fn prepare_normal (
standard_material_flags: u32,
world_normal: vec3<f32>,
world_tangent: vec4<f32>,
uv: vec2<f32>,
is_front: bool
) -> vec3<f32>

calculate_view

#
Used by 8 shaders

NOTE: Correctly calculates the view vector depending on whether the projection is orthographic or perspective.

fn calculate_view (
world_position: vec4<f32>,
is_orthographic: bool
) -> vec3<f32>

pbr_input_new

#
Used by 8 shaders

Creates a PbrInput with default values

fn pbr_input_new () -> PbrInput

pbr

#
Used by 8 shaders
fn pbr (
in: PbrInput
) -> vec4<f32>

tone_mapping

#
Used by 8 shaders
fn tone_mapping (
in: vec4<f32>
) -> vec4<f32>
