To whom it may concern,<br>
<br>
is there a way to obtain OSG classes for source code usage<br>
from the OSG .dll files without having to use windows.h<br>
to request methods, fields, constructors one at a time?<br>
<br>
If the class that I desire is located inside an OSG .dll file,<br>
how can I access that class in exactly the same way<br>
that #include allows me to do? Without having to request<br>
a method and then use it, etc...<br>
<br>
Is there something that OSG do in this particular area with<br>
regard to classes inside .dll files?<br>

This is a really complicated and exotic request.<br>
<br>
Can you maybe explain what you're trying to accomplish overall, rather than<br>
asking so specifically about the way you are trying to accomplish it<br>
presently?<br>

Hi ???<br>
<br>
The OSG has no dll specific mechanism, and while I have no WIndows<br>
expertise my understanding is part of the point of the dll is that it<br>
doesn't have a public interface, this is in the .lib.<br>
<br>
However, the OSG has support of class introspection via the<br>
serializers that are provided for the native binary/ascii/xml reading<br>
and writing. The osgDB::ClassInterface class in 3.4 onwards provide a<br>
means of querying what methods+properties are available, calling<br>
methods and setting/getting properties and creating instances.<br>
<br>
The most extensive example of ClassInterface in action is found in the<br>
OpenSceneGraph/src/osgPlygins/lua plugin that uses ClassInterface to<br>
automatically create bindings between the C++ OSG and Lua.<br>
<br>
Cheers,<br>
Robert.<br>

Subject: [osg-users] [propal] compare VertexArrayState with current<br>

Hi,<br>
<br>
What do you think of this kind of change:<br>
-adding a VertexArrayState comparator ( compare vbos and ebo and their dispatch index)<br>
-in State::SetCurrentVertexArrayState(vas):<br>
if(current->compare(vas))return;<br>
current=vas;<br>
<br>
It would add a little overcost but would be quite usefull in case Drawable can share their vas...<br>
With the current design (createvascallback) it's possible but kind of tricky..:/<br>
<br>
Thank you!<br>
<br>
Cheers,<br>
Julien<br>
