images on the sides of the model. A drawback, on the other hand, is the absence of information about metric data, such 
as point co-ordinates or distance measurements. Therefore, this software can be used only to create images of 
landscapes and animations. 
For this experiment, the following hardware was used: computer PowerMac G3 a 300 MHz; 64 MB of RAM; hard disk 
7.8 GB; graphic accelerator 64 bit; 6 MB video SGRAM; audio-video in/out 24 bit; audio recording/reproduction 16 
bit; printer Epson Stylus Photo 700. 
A model was created as follows: 
Step 1 - radiometric calibrating and photo treatment of the rectified images of facades and roofs. The images were 
improved and elements, such as trees, hedges and cars were eliminated. PhotoShop 5.0 software was used. The images 
were in TIFF format (fig. 8); 
Step 2 - manipulating of the vector file of the area in DXF 12 format with MiniCAD 7 to be exported in OPT/DB 
format; 
Step 3 - importing the file as OPT/DB format into Art.lantis and projecting the rectified images on the corresponding 
sides of the vector model; 
Step 4 - setting various 3-D views and animation . 
The result is shown in figure 9-10.
