@kroxilon/usda-parser



Allows parsing of USDA files in NodeJS and the browser.

``bash
yarn install @kroxilon/usda-parser
`

Getting Started

`ts
import {parse} from "@kroxilon/usda-parser";

const file = #usda 1.0
(
defaultPrim = "hello"
)

def Xform "hello"
{
custom double3 xformOp:translate = (4, 5, 6)
uniform token[] xformOpOrder = ["xformOp:translate"]

def Sphere "world"
{
float3[] extent = [(-2, -2, -2), (2, 2, 2)]
color3f[] primvars:displayColor = [(0, 0, 1)]
double radius = 2
}
};

const parseResult = parse(inputFile);

console.log(parsedResult, null, ' ');

`



This should produce:
