node-occ

OpenCascade nodejs extension for solid modeling.

This nodejs extension provides solid construction to nodejs. It provides a simple yet powerful javascript api to construct 3D geometry models.

This project comes with a set of V8 wrappers around OpenCascade API and a sample web application.

quick example

var occ = require('occ')

// construct a box
var box = occ.makeBox([0,0,0],[100,100,50])

// construct a cylinder
var cyl = occ.makeCylinder([50,50,-10],[50,50,60],40)

// cut the box with cylinder
box = occ.cut(box,cyl)

// save result to a STEP file
occ.writeSTEP("somefile.step",box)
