emitGlslFragment()

구문

function emitGlslFragment(
  m: ModuleDecl,
  stage?: 'vertex' | 'fragment',
  opts?: GlslEmitOptions & { entryPoints?: boolean },
): EmitFragment

매개변수

m ModuleDecl

the module to emit.

stage선택 사항 'vertex' | 'fragment'

which stage’s scope to emit; omit for the whole module.

opts선택 사항 GlslEmitOptions & { entryPoints?: boolean }

the GlslEmitOptions, plus entryPoints to keep the entries.

반환값

EmitFragment

the fragment: its source, preamble, declares and requires.

예외

Error

the same errors as emitGlslModule.

설명

The host splices the returned source into a program it assembles itself.

What the header would have carried comes back as data in EmitFragment.preamble: the #version line, any #extension … : require a declared capability needs, and the precision lines, including the ones for the integer and array sampler types derived from the module’s texture bindings. A host merges and de-duplicates those across the fragments it assembles.

Entry points are omitted unless opts.entryPoints is true. They are listed in declares.entryPoints either way, and they still decide the stage scope, so the fragment carries exactly the helpers, structs and bindings the stage’s entry reaches.

예제

import { emitGlslFragment } from 'typeshade'

const frag = emitGlslFragment(MODULE, 'fragment')
// frag.preamble: ['#version 300 es', 'precision highp float;', 'precision highp int;']
// frag.source: the declarations and helpers, ready to splice into a host program
