This project is part of the @thi.ng/umbrella monorepo.
Customizable JS code generator, compiler & runtime for @thi.ng/shader-ast.
Due to the lack of native vector operations in JS, this compile target is much more involved than the @thi.ng/shader-ast-glsl code gen and uses a pluggable backend to perform all math ops. The default backend delegates all ops to @thi.ng/vectors and @thi.ng/matrices, which altogether provide ~750 optimized vector/matrix functions.
- texture lookups (see texture tunnel demo for a monkey-patched solution)
- derivatives (
dFdx,dFdy,fwidth) - probably never supported in this env out/inoutfunction args (see #96 for discussion)
STABLE - used in production

Several demos in this repo's /examples directory are using this package.
A selection:
// AST node functions from main shader-ast pkg
import {
mul,
defn,
float,
ret,
vec3
} from "@thi.ng/shader-ast";
// codegen / compiler
import { targetJS } from "@thi.ng/shader-ast-js";
const js = targetJS();
const hello = defn("vec4", "hello", ["float"], (n) => [
ret(vec4(mul(vec3(1, 2, 3), n), -1))
]);
js(hello)
const Module = js.compile(hello);
Module.hello(10);
