By default the camera automatically detects the cluster
|
||
|
|
system it belongs to. In upper left corner we have the list
|
||
|
|
of cluster system in the scene (the cluster system in red is
|
||
|
|
the cluster system the camera is tested) and the cluster of
|
||
|
|
the current cluster system where the camera is.

Sample Specific Information
|
||
|
|
---------------------------
|
||
|
|
|
||
|
|
In the following sample some behaviour can be misunderstood.
|
||
|
|
|
||
|
|
Q: Why do I do not see the outside moving object from inside ?
|
||
|
|
A: This is because the clusters are NOT SET parent visible
|
||
|
|
|
||
|
|
Q: Why do I see all from rootCluster ?
|
||
|
|
A: This is because the clusters are SET visible from parent.
|
||
|
|
|
||
|
|
Q: Why ?
|
||
|
|
A: Because if we do not set any cluster visible from parent nor
|
||
|
|
parent visible there is no link between 'landscape' and the cluster
|
||
|
|
system.
|
||
|
|
|
||
|
|
Q: But I dont want to see the whole inside of my house from the
|
||
|
|
landscape so what can I do ?
|
||
|
|
A: This is simple. Make a door which will be a portal to the outside.
|
||
|
|
Put the door in 2 clusters one which is inside the house and the
|
||
|
|
other outside. Flag the outside cluster with parent visible and
|
||
|
|
visible from parent flags. And voila you've got your house indoor
|
||
|
|
no more visible from anywhere outside the house. Take care of the
|
||
|
|
portal orientation. The normal must point outside the house.
|
||
|
|
|
||
|
|
Q: Ok I have those things works but when my moving objects are inside the
|
||
|
|
house this is like they are outside.
|
||
|
|
A: Yes because there are no automatic detection for the moving object.
|
||
|
|
You have to get this information from the PACS system and give it to
|
||
|
|
the Cluster/Portal system through the setClusterSystem function.
|
||
|
|
|
||
|
|
Q: What if my moving objects are using skeleton animation.
|
||
|
|
A: You will need to use setClusterSystem for the skeleton
|
||
|
|
only, the shape will inherit the visibility of the skeleton.
|
||
|
|
|
||
|
|
Q: ok thanks
|
||
|
|
A: you're welcome :)
