Need an addition to current website. Currently using Joomla CMS with two Joomlabamboo templates plus a Freelance extension by Joombri. I would like to have an add-on platform to my website using three.js. A good example of what I need created is at https://sketchfab.com. This will not be a home page but an addition to my site. Guests will be allowed to view but have to register to upload and download. I currently already have registration on my website and the addition will need to run through this. I would also like the ability for registered users to drag and drop files on upload. I will also need the ability to change or add file types for upload as there are many file types for 3D design. STL being the main file type but would like to add newer ones if needed. My site is not completed yet and am still working on other aspects of it.
