About

Interactive 3D simulators.

SimulatorsIn3D explains a subject with a model you can turn and inspect. One page, one simulator.

Each page is one model. You can turn it, look at the parts, and read what the model is showing, in ordinary language.

There is no reader account. Pages are added one at a time, and the ones already published stay in the catalog.

If a visit counter is switched on, every public page loads the same snippet, either Google Analytics or Matomo, from a single file. Nothing is counted until that is switched on. The admin pages are marked so search engines do not index them.
