Protect your content
The 3Space file format allows you to protect your work that you want
to show on the Web. To protect your 3D contents, you must lock the file
contents to a specific URL.
Locking 3Space geometry files using the ZAPlock utility program
Background:
It is sometimes necessary to protect the content of a 3D file from being
copied or stolen. You may want to display your creations but you don't
want someone to take your file and reuse it without your permission.
3Space uses the TGS ZAP file format to store geometry and XML tags to
describe the scene behaviors.
Although it is nearly impossible today to protect XML content, we can
protect
the geometry files.
The ZAP file format allows you to lock the file content to a specific
URL.
Locking, in this context, means that you attach the file to a specific
location on the web (your web server address). When the ZAP player plug-in
loads that file, it compares the file location to the URL stored in the
file.
If they are different, it refuses to display the objects.
Once locked, the file cannot be opened with an authoring too.
The only way to edit it is to unlock it with ZAPlock -u.
We highly recommend saving all the using the native file format
of the authoring tool (for instance Amapi file format .a3d) to be able
to export
safely to 3Space in case of modification. This method will keep all the
original information in the .a3d file.
Usage:
ZAPlock is a command line tool. It must be used from a DOS shell.
-c or -change: change the current password setting
-h -help: display this message
-l or -list: list current lock information
-np or -newpassword "password": set a new password
-nu or -newurl: set a new URL target
-p -password "password": the current password to unlock the
file
-u or -unlock: unlocks the ZAP file
For instance:
- to lock a ZAP file:
ZAPlock -c -p oldpassword -np newpassword -nu http://www.myweb.com/
-o locked.z3d myzapfile.z3d
- to unlock a ZAP file:
ZAPlock -u -p password myzapfile.z3d
- to check if a ZAP file is locked:
ZAPlock -l myzapfile.z3d
- to view the URL lock of a ZAP file:
ZAPlock -l -p password myzapfile.z3d
