Do I need to install any software on my device to use the interactive viewer?

No. We’re using technologies called WebGL and X3DOM (pronounced X-Freedom) that are designed to work in modern web browsers without special software. However, It’s possible that some web browsers won’t display the content in 3D-viewable format automatically. Try using later versions of Firefox or Chrome, if possible; if that doesn’t work, contact us at 3Dprint@nih.gov and we can help you to troubleshoot so you can manipulate the models on the screen.
