 * Convert standard camera intrinsic and extrinsic parameters to a vtkCamera instance for rendering

 * focal_len : camera focal length (units pixels)
 * nx,ny : image dimensions in pixels
 * principal_pt: camera principal point,
 *    i.e. the intersection of the principal ray with the image plane (units pixels)
 * camera_rot, camera_trans : rotation, translation matrix mapping world points to camera coordinates
 * depth_min, depth_max : needed to set the clipping range

xaliphostes

A small multi-threaded C++ library (so, does not include any main) compiled with emscripten and pthread running under the main thread in the browser, a web worker or using node.js.

Note: Emscripten will produce lib.js.

Using a web browser

Running this lib in the main thread is fine but, obviously, block the main thread. Running it using a web worker leads no error with modification of the worker script (see below)

Using node.js

Run fine except that it prevents Node app from ever exiting.

It appears links for later updates than 4.22.1 are currently (as of early Aug 2024) being kept up to date on https://docs.docker.com/desktop/release-notes, I'm not going to continuously update this but others may in the comments below, so check that link or the comments if you need a later version than 4.22.1.

The information may not be correct in all cases, or may have changed since archive.org archived the page. At time of posting, I spot-checked a few links and they appeared to be good, but really, all I've done is copied, pasted, and visually formatted the information I found on archive.org, so no warrantee that it's good.  

If the download links don't work, sometimes archive.org has the download archive, and you can try adding https://web.archive.org/web/20230911135706/ to the beginning of the URL. For instance, as of this writing, the 4.22.1 Windows download i
