How to load 3D CAD data into three.js. Part 2.

1. Using GLTF as an interim format

In addition to OBJ, STL and VRML mentioned in the previous blog, there is also GLTF (GL Transmission Format). The GLTF format is a “JPEG of 3D” format standardized and promoted by the Khronos group.

2. More details on the .cdxfb format used in CAD Exchanger Cloud

When working on CAD Exchanger Cloud we had to design our own format that we could use to save the data in on a server and restore from on a client. We obviously could not use any of the above motioned formats supported by three.js (STL, VRML, OBJ, GLTF) as they are much more limited than what CAD files can generally contain. For instance, none of them is capable to contain B-Rep information, PMI or layers.

3. Detailed example of CAD Exchanger Web Toolkit

After publication of the previous post we had been working on updating our web-site and adding more relevant details on each product we offer. With that, we added a dedicated page on CAD Exchanger Web Toolkit (which we formerly referred to as “Web SDK” but decided to rename it to avoid confusion with “CAD Exchanger SDK”).
