Tips for using the 3D Viewers

We are continually working on tuning the 3D viewers for better performance. Keep in mind that interactive 3D rendering can require memory and CPU resources on the browser, and that performance on underpowered computers or bad network connections might be less then optimal

The FaceBase 2 Data Browser includes interactive 3D viewing when datasets include 3D images.

Note that 3D viewing requires WebGL. It's enabled by default on the latest versions of browsers, but requires a certain amount of memory and bandwidth. See this page for more information if you're having issues viewing the images.

Here is a detail page of a dataset that includes some 3D images. We'll scroll down to and expand the Preview section...

The 3D viewer allows you to use your mouse and keys to manipulate the view:

Note that Internet Explorer 11 only supports the ability of using the mouse wheel to zoom in and out.

Tools and Tips

Here are some tools and tips:

Enable WebGL

Make sure WebGL is enabled for your browser. WebGL (Web Graphics Library) is a JavaScript API for rendering interactive 3D and 2D graphics within any compatible web browser without the use of plug-ins and is supported by recent browsers. However, sometimes you need to configure a particular setting (specifically for Safari) or upgrade your hardware.
