A type of shading.

Variants

FunctionBased

A function-based shading.

Fields

domain: [f32; 4]

The domain of the function.

matrix: Affine

A transform to apply to the shading.

function: ShadingFunction

The function that should be used to evaluate the shading.

RadialAxial

A radial-axial shading.

Fields

coords: [f32; 6]

The coordinates of the shading.

For axial shadings, only the first 4 entries are relevant, representing the x/y coordinates of the first point and the coordinates for the second point.

For radial shadings, the coordinates contain the x/y coordinates as well as the radius for both circles.

domain: [f32; 2]

The domain of the shading.

function: ShadingFunction

The function forming the basis of the shading.

extend: [bool; 2]

The extends in the left/right direction of the shading.

axial: bool

Whether the shading is axial or radial.

TriangleMesh

A triangle-mesh shading.

Fields

triangles: Vec<Triangle>

The triangles making up the shading.

function: Option<ShadingFunction>

An optional function used for calculating the sampled color values.

CoonsPatchMesh

A coons-patch-mesh shading.

Fields

patches: Vec<CoonsPatch>

The patches that make up the shading.

function: Option<ShadingFunction>

An optional function used for calculating the sampled color values.

TensorProductPatchMesh

A tensor-product-patch-mesh shading.

Fields

patches: Vec<TensorProductPatch>

The patches that make up the shading.

function: Option<ShadingFunction>

An optional function used for calculating the sampled color values.

Dummy

A dummy shading that should just be drawn transparent.

Trait Implementations
