Fragment shader environment.

This type contains everything you have access to when writing a fragment shader.

Fields

frag_coord: Expr<V4<f32>>

Fragment coordinate in the framebuffer.

front_facing: Expr<bool>

Whether the fragment is front-facing.

clip_distance: Expr<[f32]>

Clip distances to user planes.

This is an array giving the clip distances to each of the user clip planes.

cull_distance: Expr<[f32]>

Cull distances to user planes.

This is an array giving the cull distances to each of the user clip planes.

point_coord: Expr<V2<f32>>

Contains the 2D coordinates of a fragment within a point primitive.

primitive_id: Expr<i32>

ID of the primitive being currently rendered.

sample_id: Expr<i32>

ID of the sample being currently rendered.

sample_position: Expr<V2<f32>>

Sample 2D coordinates.

sample_mask_in: Expr<i32>

Contains the computed sample coverage mask for the current fragment.

layer: Expr<i32>

Layer the fragment will be written to.

viewport_index: Expr<i32>

Viewport index the fragment will be written to.

helper_invocation: Expr<bool>

Indicates whether we are in a helper invocation of a fragment shader.

frag_depth: Var<f32>

Depth of the fragment.

sample_mask: Var<[i32]>

Sample mask of the fragment.
