[GRASSLIST:9048] Re: 3D blocks again

[Ing.Peter Misovic]

Hi Dylan,
In fact I have 3D matrix of points. Nature of data source is table in
postgres/Postgis with columns : x, y, z, the_geom (for 3d point) etc.
X,Y,Z are coordinates of centroid. I need display those centriods like
cubes (or it's better to say cuboids, blocks, not cube) with specific
colour. If it is possible in PovRay do I have to use grass ? Or Did
you mean to use GRASS for generate cubes and there export it into
POVRAY ? Or how did you mean it ?

Thank you very much for your time and effort you spent with this problem.


Peter
