[postgis-users] custom data type on basis of 3d geometry type?

[Paragon Corporation]

B.,

I think one was already done or started by CamptoCamp folk but not
integrated into PostGIS.  Check out these links
 
http://postgis.refractions.net/support/wiki/index.php?FeaturesOfPostgis
 
And the recent X3D / TIN discussion threads -

Hope that helps,
Regina

Hello everyone,
 
I was wondering whether postGIS has the option of building a custom data
type on top of an existing data type, like a 3d geometry type. In postgreSQL
you can build a custom data type on top of an existing one, but I cannot
find any examples for postGIS. 
 
Could anyone please clarify this issue to me or point me into the right
direction.
 
Thanks a mill,
B.
