How to use this web site

The media panel

Most images, videos and other multimedia elements on this web site are displayed in the media panel in the right half of the browser window. Whenever you click a link that points to a multimedia element, the media panel will show up. Except for browser window widths below 800 pixels, it will not cover the text area of the page, so that you can continue to read while you view complementary multimedia elements. To hide the media panel again, click the close button in it's upper left corner.

The 3D point cloud viewer

This web site features a 3D point cloud viewer. It allows interactive exploration of the laser scan data sets which were produced in the course of this project.

To use the 3D point cloud viewer, your computer needs a reasonably fast 3D graphics acceleration chip and a web browser that supports WebGL. Also, JavaScript must be enabled. We recommend an up-to-date version of Google Chrome or Mozilla Firefox. Microsoft Internet Explorer is currently not supported.

To open the 3D point cloud viewer in the media panel, click on a link that features the eye symbol, like this one , or select "3D Point Cloud Viewer" from the "Media" menu at the top of the page.

Navigating the point cloud

You can control the point cloud viewer using your keyboard and mouse.

To move around, click the viewer area with your mouse once and then press and hold one or multiple of the following keys:

Your viewing direction will not change when you do this.

To rotate your view, move your mouse over the point cloud viewer area, hold the left mouse button pressed and move the mouse

You can also move around and rotate your view simultaneously. Keep in mind that when you change your viewing direction while moving around, your movement direction will change, too. This is because all movement is relative to your current "forward" direction. When you look around, "forward" becomes something different - and so will your direction of movement.

Confused? Open the point cloud viewer and practice a bit!

The Google Maps Plug-In

Another useful feature of this web site is the Google Maps plug-in. It provides a map that can be panned and zoomed. The hard- and software requirements for the map plug-in are much lower than those for the point cloud viewer. It will probably work fine even in older or less capable browsers like Internet Explorer, as long as JavaScript is available and enabled.

Watch out for links with the map symbol, like this one. Clicking them will open the map and show points of interest. Alternatively, you can open the map by selecting "Google Maps" from the "Media" menu.

You can pan the map by holding the left mouse button pressed and moving the mouse around. To zoom in and out, scroll the mouse wheel.
