For many years, there was simply no solution to a single problem that plagued many property builders. The problem was that there was not a central database that could show all of the house designs using a single program or application. This meant that a potential property buyer would need to go from location to location to look at all of the different homes for sale. However, a technical solution appeared that finally addressed this pressing need.

The name of the new software was Unrealty and it had a specific purpose that no other program was capable of delivering. Unrealty allowed a person to create a 3D model of a neighborhood or area where all of the properties could have a full resolution where a buyer could view everything from a single computer terminal. This took much of the work out of home buying and made it easier for the potential buyer to narrow down their selections to a small number and then visit these properties to see them first hand.

The way that Unrealty worked was that it was the first to put a first person view onto a landscape. Where previous programs used CAD as the model, Unrealty wanted to show that a real life experience was possible from a computer. However, the real estate market was not where Unrealty gained its largest usage.

Although many people realized the value that Unrealty could bring to the real estate market, it was the game developers that quickly customized the program to fit their own needs. For years, they had been looking for a way to model a game design in a first person view, but with little success. The elegant solution of Unrealty finally made this possible. The rendering engine for Unrealty used a "what you see is what you get" perspective, making it perfect for gaming operations. This includes different levels of lighting, placement of textures, and geometrical operations. The advantage of Unrealty over competing layout programs is that it was able to render the images much faster than Quake or other similar applications. In this way, the game would not suffer from lag due to rendering issues. However, it was not this improved rendering that was the main attraction of the program.

What drew many designers and developers to Unrealty was the realism that was part of the software package. Developers were able to add photorealistic textures up to a certain resolution to the existing layout. This means that instead of having a static computer generated image, a programmer could use a photo as the actual texture, giving a more lifelike experience for the end user. In addition, all of the elements are not inherent in the program, meaning that furniture and other items can easily be added in real time and do not have to be hard coded into the application's source code.

As the advancements in computer processor speed have rapidly progressed, the ability to use Unrealty as a design engine has also improved. Unrealty was actually well ahead of its time, only being suitable for a state of the art computer with 64 mb of RAM and a 200 mHz processor. The new computer designs are more than capable of running Unrealty and thus more designers are using the program to its maximum potential. With the new high powered computers developers are working together in real time to create realistic and highly detailed maps and landscape layouts that can be much larger than in previous times. The architectural and gaming uses of Unrealty have brought it to the forefront of layout rendering and it is now being used in many different ways.
