[osg-users] OSGVisual SVN Access
Hi, I have been trying to check out OSGVisual from its SVN with the command described on the OSGVisual Website's download page (I cannot post it because I am a new user here). However, it is asking me for credentials for both a username and password. I just need to read it, as I am trying to hook up a 3D Mouse to a product. I can use the online trac page, but navigating through source with that is painful. I heard that Toben frequents these forums and I hope to get some guidance on how to checkout OSGVisual. Thank you!

Am I missing something here? Probably not. The underlying integral type for the enum Type could be (and probably is) int8_t. That implies that possible values for the user type should be within range +- 127 or the conversion to Type will be undefined.

Re: [osg-users] Using a custom StateAttribute
Hi,
An attribute is identified by a type (enum Type) and a member (int). The
StateAttribute getters and setters have the member parameter defaulted
to 0.
I use some custom state attributes:
- I use the type as an attribute class (i.e. MATERIAL for BRDF related
parameters...)
- I use the member of prevent conflicts with the OSG legacy attributes

Hi,
How is one supposed to use a custom StateAttribute?
The docs say that:
"When extending the osg's StateAttribute's simply define your own Type value which
is unique, using the StateAttribute::Type enum as a guide of what values to use"
As it is, returning a unique value simply isn't possible because the getType()
function returns an enum:
/** Return the Type identifier of the attribute's class type.*/
virtual Type getType() const = 0;
Type is the enum defined here containing the default types, with no room for
user types:
Code:
enum Type
{
TEXTURE,
POLYGONMODE,
FRAME_BUFFER_OBJECT
};
I suppose that you could choose some integer, static_cast it back to enum Type
and then hope that will work. (it will most likely work if the enum has a large
enough bit size, but it's technically undefined behaviour, so I can't imagine
that's how Robert intended it to be used).
To me it seems the feature advertised in docs of creating your own
StateAttributes simply isn't possible, just because of this one function
returning enum instead of int, which would be an easy fix. Am I missing
something here?
Cheers,
Jannik

Re: [osg-users] GL3 Context in MFC
Something I forgot to mention, I am using osg 3.4.0. Even if someone managed to get GL3 to work with osg 3.2.x using MFC, that would be helpful. Atleast maybe I could try to track the changes that caused it to stop working. ... Thank you!

Re: [osg-users] OSG BOF at SIGGRAPH was a SUCCESS
Greetings all! Just to let you all know that I got some interest in showing how to add excursions (a.k.a. buildings like the Boston demo that Pelican wiped up). I know that there was a lot of questions that I had in the BOF on this and I did a similar map for someone else's demo and I would like to do an illustrated how-to video on YouTube if there is any interest in that subject! For others that don't know, I have done a how-to for Virtual Planet Builder that included how to compile the code in MS Windows using Visual Studio Express 2010. ... Thank you!
