The WYSIWYG app allows very elaborate 3D objects to be created. HTML and CSS code are developed on the fly and can be edited using Tridiv.
The editor offers a four-pane interface traditionally found in 3D modelling apps, as well as an interactive preview pane of the final design.
Shading, dynamic lighting and shadows can be added very simply.
The web app currently runs on Chrome, Safari and Opera.
