Struct ExtendedMaterial

pub struct ExtendedMaterial<B, E>
where
    B: Material,
    E: MaterialExtension,
{
    pub base: B,
    pub extension: E,
}

A material that extends a base Material with additional shaders and data.

The data from both materials will be combined and made available to the shader so that shader functions built for the base material (and referencing the base material bindings) will work as expected, and custom alterations based on custom data can also be used.

If the extension E returns a non-default result from vertex_shader() it will be used in place of the base material’s vertex shader.

If the extension E returns a non-default result from fragment_shader() it will be used in place of the base fragment shader.

When used with StandardMaterial as the base, all the standard material fields are present, so the pbr_fragment shader functions can be called from the extension shader (see the extended_material example).

Fields

base: B

extension: E

Trait Implementations

impl<B, E> AsBindGroup for ExtendedMaterial<B, E>

where B: Material, E: MaterialExtension,

type Data = (<B as AsBindGroup>::Data, <E as AsBindGroup>::Data)

Data that will be stored alongside the “prepared” bind group.

type Param = (<B as AsBindGroup>::Param, <E as AsBindGroup>::Param)

fn unprepared_bind_group( &self, layout: &BindGroupLayout, render_device: &RenderDevice, _: &mut <<ExtendedMaterial<B, E> as AsBindGroup>::Param as SystemParam>::Item<'_, '_>, ) -> Result<UnpreparedBindGroup<<ExtendedMaterial<B, E> as AsBindGroup>::Data>, AsBindGroupError>

Returns a vec of (binding index, OwnedBindingResource). In cases where OwnedBindingResource is not available (as for bindless texture arrays currently), an implementor may define as_bind_group directly. This may prevent certain features from working correctly.

Returns a vec of bind group layout entries
