[osg-users] ADD_LIST_SERIALIZER giving compilation error
Hi,
I have a class which is derived from osg::Object and it has following set
and get method:-
void setData(const std::vectorDataXY);
const std::vectorDataXY getData() const;
where DataXY is following structure:-
struct DataXY
{
double x;
double y;
};
After adding following line in the body of REGISTER_OBJECT_WRAPPER
ADD_LIST_SERIALIZER(Data, std::vectorDataXY);
I am getting following compilation error:-
C:\OpenSceneGraph-3.0.1\include\osgDB/Serializer(715): error C2678: binary
'' : no operator found which takes a left-hand operand of type
'osgDB::InputStream' (or there is no acceptable conversion)
Please advise me how to resolve this issue.
Regards,
Mukundan

Re: [osg-users] Unwanted effect with two effect nodes in the line of sight (see-through)
Hi David and all, thank you for taking your time to answer this. To make things clear, I am using self-written subclasses of the Effect class (from the osgFX namespace). Simply adding the second pass to the transparent bin did not help. Though I have to admit I do not have the expertise (yet) to understand the interaction between multi-pass and multi-bin. I suspect that I need a transparency effect in two passes, not in one pass. This would explain why the single pass transparency occludes my second pass of the other effect node, right? I would like to understand this a bit more, before I start trying things out, so my question are: 1. how do multi-pass and multiple bins play together? 2. if have nodes using two-pass rendering, does my transparency effect node also need two-pass (AND transparent bin) in order to take effect OVER the other effect nodes? As another hint: I am also using the built-in osgFX::Scribe node which suffers from the effect, that the scribed nodes gets completely occluded by the transparent wall (left, in the attached screenshot scribe-gets-occluded.png). Thank you!

[osg-users] Reference pointer pattern question?
Hi,
I was looking at Don Burns text from 2003 about reference pointers in osg
(sadly no longer available online, although it can be found via Internet
Archive sites.) But this got me thinking about the suggested pattern for
returning pointers from methods.
Looking through different parts of the osg source code you can find two
different patterns for returning pointers of object whose class inherits from
osg::Referenced.
Pattern 1:
Code:
osg::ref_ptr osg::Node createObject()
{
osg::ref_ptr osg::Node objectPtr = new osg::Node;
return objectPtr;
}
Pattern 2:
Code:
osg::Node* createObject()
{
osg::ref_ptr osg::Node objectPtr = new osg::Node;
return objectPtr.release();
}
Is one of these preferred? If so why?
Regards
Björn

Re: [osg-users] Reference pointer pattern question?
Hi Björn,
Returning a ref_ptr is more safe w.r.t memory management, forcing
the user to use ref_ptr themselves, but no as efficient as just
returning a C pointer.
In my own code I typically just pass a C pointer back as as long as
your aware of what you are doing avoiding the pitfalls isn't
difficult.
Robert.

You can disable compression when doing the VPB build by choosing an RGB output format. Run osgdem --help to see all the options. Robert.

The pattern looks a bit like quantization noise but we are setting --disable-error-diffusion just in case and the target has compression disabled using -RGBA. Does anyone in OSG land have an idea where I can look to see what is causing this? I'm attaching captured images where I've applied the same stretching formula. One is from the rendering of the database and the other is from Mathcad, where I loaded the source image and displayed it with the same stretch.

[osg-users] [build] Cmd line cmake for OSX under 10.9
Hi, I've had success building for 10.8.x in the past, using a simple .sh script to set cmake on its way. Upon switching to 10.9 and using XCode5-DP6, I'm having problems getting cmake to see OpenGL.

Re: [osg-users] [build] Cmd line cmake for OSX under 10.9
The magic gnomes visited. I deleted my source tree and re-checked out. Still no luck. Now it can't even find stdlib.h. Hmm. I then tried various other versions of Xcode via xcode-switch, and found my old xcode4.6.3 wasn't installed properly. Not that it worked when I fixed that, because the scripts pick up a SDK of 10.9 which isn't supported by 4.6.3. Anyway; I switched back to xcode5-dp6, rebooted for some other reason not related to this problem at all, and low and behold while I was messing with other things the gnomes visited and fixed everything. How odd. I wonder ... who let them in? Anyway; for reasons unknown to mortal man it's now working.
