1) I want to use anti-aliasing in my program. I tried:
a) "pfAntialias(PFAA_ON)" after opening the window.
It had no effect.
b) "gstate->setMode(PFSTATE_ANTIALIAS, PFAA_ON)".
It made the polygons COMPLETELY black
what should I do to make anti-aliasing work ???
2) I need to find a node in a performer-tree by a name. I use "lookup"
for
the job. In one of the cases, where the tree is:
----------
| grp |
----------
/ \
-------- -------
|sphere| |Persp|
-------- -------
|
--------
|geode |
--------
I write "animation_nodes[i] = grp->lookup(obj_name,
pfNode::getClassType())",
and I get "NULL" for "obj_name" which is "sphere".
In a few other cases it works.
I by-passed the problem by querying specifically for all the
node-types (i.e lookup(obj_name, pfGeode::getClassType() etc..),
but isn't there a way to make it work for "pfNode::getClassType()" ??
3) I have a pfHighLight problem. The source is:
if (pfIsOfType(node, pfGeode::getClassType())) {
pfGeode *geode = (pfGeode *) node;
pfHighlight *highlight = new pfHighlight;
highlight->setMode(PFHL_LINES);
highlight->setColor( PFHL_FGCOLOR, 1.0, 1.0, 1.0);
for (int i = 0; i < geode->getNumGSets(); i++) {
geode->getGSet(i)->setHlight(highlight);
geode->getGSet(i)->getGState()->setMode(PFSTATE_ENHIGHLIGHTING,PFTR_ON); }
}
It works FINE on an ONYX R10000, running IRIX 6.2 and Performer 2.1,
and
on Indy's running 5.3 and Performer 2.0, it crashes for certain
nodes.
All these geode-nodes are childs of pfMorph.
BUT - if I change the mode to "highlight->setMode(PFHL_NORMALS)"
or "highlight->setMode(PFHL_BBOX_LINES)"
then it works !!
Is there a known bug of Performer or Irix that prevents highlighting
in few of the modes ??
if not - what might be wrong with my code ??
If someone knows one of the answers. please let me know.
Thanks in advance.
