The above picture shows the Dam maximum displacement, combined with a city model.

Problem to tackle:

Each house in the photo should be consistent in color because each house is assigned a single value for their color. But here it is not consistency in their color.

Possible reasons:

1.       There would be a possibility for some bugs in my program which is used to make POV file.

2.      There would be a possibility for missing mesh data in database.

3.      There would be a possibility for some bugs in POV-ray software itself.

Now I have been working on all possible scenarios to tackle above trouble.
