If you have an interest in real time 3D ( or low cost 3D perspectives ) you should take a moment to check out this truly amazing new concept in 3D.
This solution that has been created using a proprietory software solution that has taken 4 years to develop.
Basically you start with either selecting a stylized room template or have a model of a specific building created for you, and then you create a fully interactive 3D walk through model where you can explore hundreds of colours, materials, objects even design landscaping to suit the project - most importantly its inexpensive and any anyone can do it.
