Description
This module accepts a web-based URL pointing at an AVS/Express geometry data file hosted by a WWW server. The geometry data file is then cached locally and read as though it were a local geometry.
Input
none.
Parameters
URL
Specify a valid URL address in this field. The ReadWebGeom module will read and cache the contents contained at that location. If the URL is invalid or points to unretrievable information, the phrase " URL contains no data " appears in the Status parameter.
OutFile
The location of the URL content cache. It is also the port that is used as input to another AVS/Express data reader. The default location is /tmp/xp_out.da t, but you can change the location at any time.
If two URLs are fetched in a row, the contents of the second URL overwrite the contents of the first URL if the location of the cache file is not changed. The OutFile _parameter receives an notify _event after every valid URL retrieval.
Status
A text field that contains status information for the current URL fetch. Messages are displayed in this field as the URL collection progresses; these messages are described in W3Cget_URL .
Output Port
Example
Not available
File
v/w3c.v
