As part of the Xtrad Editor WordPress plugin I have made available the enhanced three.js editor for standalone use. Although the editor is used by Xtrad Editor to create 3D Scenes for use on WordPress Pages the standalone editor is meant to show the functionality only, but I thought people might like to see the enhanced editor:
Feel free to play with it.
I have just added fire to the editor for use with 2D Text and standalone. The standalone fire can be added from the menu, Add Other/Complex Object. Its parameters can be changed on the GEOMETRY TAB.
If you read this Mr doob would it be possible to add your sketches as templates for people to play with. I will credit you.
