This is a web tool for easily creating 3D meshes from greyscale images. It was designed to be a free and portable way to view and create 3D models without the need to download software or use complex tools.
Much of the underlying 3D functionality is provided by the excellent Babylon.js engine, which provides functions for heightmapping, rendering and file creation.
You can generate a random model or upload a greyscale image from your phone, tablet or computer. Images can be dragged and dropped onto the canvas, if you prefer. After an image is added, it will automatically be converted into a 3D model.
The way the model is rendered can be controlled, with toggles for
turntable, wireframe and show grid, as well as colouring.
Models can be rotated by dragging over the model with the left mouse button or by swiping on a touchscreen. Zooming is controlled using a scroll-wheel or by pinching on a touchscreen. Panning can be achieved by dragging with the right mouse button. Arrow keys can also be used to control the camera as long as the model is focused (i.e., it has been clicked).
Currently the models can be exported to .stl, .obj and .glb formats.
When tested with Blender, all models were imported in the correct
orientation.
In other software models may need to be rotated into place.

Ephtracy's aerialod is an amazing piece of software for rendering high quality 3D models from images and offers a high degree of customisation. The software is Windows-only and does not support mobile devices.
I obtained some of the example heightmaps from the internet and assume they are free to use. If you recognise an image of yours that you would like me to credit or remove please let me know.
I plan on replacing some or all of them with original images.
