resource()

구문

function resource<T extends ShaderType>(
  name: string,
  type: T,
  at: { group: number; binding: number; space?: AddressSpace },
): Resource<T>

매개변수

name string

the emitted binding name, which is also the name a host binds by.

type T extends ShaderType

the resource’s type, such as texture2dfT, texture2dArrayfT or samplerT.

at { group: number; binding: number; space?: AddressSpace }

the group and binding slot, and optionally the address space.

반환값

Resource<T>

the Resource handle, .binding and .node.

설명

The binding declaration and the access node come from this one call.

.node keeps the specific key of the type you passed: Node<'texture_2d<f32>'>, Node<'sampler'>, Node<'texture_2d_array<u32>'>. That is what makes the texture calls type-checked at the authoring line: textureSample takes a sampled 2D texture and a sampler in that order, so swapping them is a tsc error, an integer texture is rejected where filtering has no meaning, and an array texture requires its layer argument.

.binding goes in module({ bindings }), or pass the handle in uses. The address space defaults to 'uniform', the texture and sampler convention.

예제

import { resource, textureSample, texture2dfT, samplerT } from 'typeshade'

const tex = resource('tex', texture2dfT, { group: 0, binding: 1 })
const smp = resource('tex_sampler', samplerT, { group: 0, binding: 2 })
const c = textureSample(tex.node, smp.node, uv)
