Hello All, Jay T -
I am currently building a solution for text-commands to a 3dmodel.stl. It is a way out, what i have here is super beta.....I use python to run flask and subprocess to run a script. viewer.py runs solidstl.py with visualization by Open3d. Open3d is to broadcast the part.stl with
WEBRTC.....
so I have begun however cannot finish yet...
CODE:
Viewer.py

from subprocess import Popen, PIPE, STDOUT
from flask import Flask, Response, request, render_template, redirect, url_for
app = Flask(__name__, static_folder='fishvid')
app.url_map.strict_slashes = False
@app.route('/stl')
def out():
def output():
yield """<html><head>
