The basic categories of software programs designed for clients and potential customers include: home planning aids, interior design packages, CD-ROM marketing tools, Internet sources, and virtual reality models.
Since visualizing the completed structure from a set of constructional drawings is difficult for most people, hand-drawn pictorials and three-dimensional models were commonly used. However, these methods frequently failed to provide enough detailed information for decision making. With the computer that is no longer the case. Now designers can show clients photo-quality representations that display every detail of a building plan. Besides,numerous easy-to-use software programs help customers select home furnishings, arrange them in a living space, and see the arrangement in a realistic fashion.
The most impressive part of virtual reality models is that a person can ‘walk’ through a house and ‘see’ its finished appearance before any construction begins. The client can enter any room and even look out a window. Another advantage of the virtual model is that the computer can modify elements in the interior, such as removing a wall or changing carpet colors, with the click of the mouse.
