What's the best way to import STL files in Three.js?

Currently, I am developing an application tailored for mechanical design and simulation tasks. Our goal is to incorporate Three.js for loading and visualizing parts created in Solidworks, most commonly exported as STL files in text or binary format.

Although Meshlab can convert STL files to OBJ or other formats, I find this extra conversion step to be an unnecessary burden on the workflow.

While Three.js offers support for Collada, OBJ, UTF-8, VTK, and JSON loading solutions, it lacks a clean example of STL support. I have come across some past solutions like https://github.com/tbuser/thingiview.js/blob/master/javascripts/thingiloader.js which I wish to avoid due to licensing, and https://github.com/tbuser/three.js/blob/master/utils/stl_geometry.js which does not seem fully integrated.

Could there be a solution that I have overlooked?

Answer №1

In the world of Three.js, there exists an incredible tool known as the STLLoader, along with a fascinating example demonstrating how to utilize it. It's worth noting that these additions were made to Three.js in August of 2012, shortly after the original posting of this question. Subsequently, there have been numerous commits related to the STLLoader.
