|
|
* itself. In the order from weakest to strongest restrictions, the possible

|
|
* flags are:
|
||
|
|
*
|
||
|
|
* PT_drop_node - This node should be removed at the next flatten call.
|
||
|
|
*
|
||
|
|
* PT_none - The transform may be adjusted at will. The node itself will not
|
||
|
|
* be removed. This is the default.
|
||
|
|
*
|
||
|
|
* PT_net - Preserve the net transform from the root, but it's acceptable to
|
||
|
|
* modify the local transform stored on this particular node if necessary, so
|
||
|
|
* long as the net transform is not changed. This eliminates the need to drop
|
||
|
|
* an extra transform on the node above.
|
||
|
|
*
|
||
|
|
* PT_local - The local (and net) transform should not be changed in any way.
|
||
|
|
* If necessary, an extra transform will be left on the node above to
|
||
|
|
* guarantee this. This is a stronger restriction than PT_net.
|
||
|
|
*
|
||
|
|
* PT_no_touch - The local transform will not be changed, the node will not be
|
||
|
|
* removed, and furthermore any flatten operation will not continue below this
|
||
|
|
* node--this node and all descendents are protected from the effects of
|
||
|
|
* flatten.
