3dViewMeasurement

This repository is an update of 3DView.Measurements with the last threejs library (release 143)

conversion process :

* convert class to es6

* change deprecated method 

Advanced JavaScript 3D models viewing control with interactive measurements

Description

3D viewing control with interactive measurements based on Three.js.

Supports:

• All modern browsers (including mobile)
• WebGL or Canvas rendering
• all type of loader (ply and stl tested, show example html file)
• Point info and distance measurements (feel free to develop thickness, angle and radius measurements 💪 🙏 😃 💥)
• Getting information about selected point on a 3D model (coordinates, face, normal)

This code creates a renderer; loads the STL file; request the user to add a measurement and listens to measurement events.
