Geographx works closely with the developers of K2Vi, a fast rendering, real-time 3D visualisation virtual reality platform. Much of our data is optimised for use with this software, and the K2Vi Globe V3 Viewer has been used to create a number of the graphics featured on this site.
Interactive 3D

A cost-effective way to communicate a vision is to model a proposed development in a dynamic, interactive virtual environment. This technology is increasingly used as part of the environmental planning process and for community consultation. A 3D simulation can also prove a useful marketing aid

To build a simulation we need site-specific data which we then place into a 3D map of the wider area. Site data is usually provided by the client, and may consist of:

• A site survey with elevation values
• High resolution orthophotography
• CAD/GIS or other data detailing layout, planned site development and landscaping
• Plans or 3D object models for buildings and other key structures.

Once completed, it is possible to walk through or fly around an interactive 3D simulation at will.
Virtual Tours
A video clip of a virtual tour or fly-through may lack the power and flexibility of an interactive 3D simulation, however it does offer two clear advantages. One, you don't need a 3D Viewer and a smart computer. Two, the presenter need not learn to "fly".

We produce video footage by creating a flightpath in the K2Vi freeflight environment, and exporting sequential screenshots which are then stitched into a video clip. This can then be written to CD or DVD, and presented to an audience using standard video player software.

Videos can be optimised for datashow presentation or web viewing.

Oblique Images
Frequently we are asked to provide a still image - an aerial, oblique, panoramic view of a particular location or area.
These images can provide the base map for an outdoor interpretation panel, a routemap or flightpath for a company brochure, or, as in the example illustrated below, a companion 3D perspective to a conventional 2D plan map.

Geographx can supply, at short notice, aerial oblique images for any location in New Zealand.
