Re: [osg-users] set render bin details

The render bin # is just an integer, so you can use INT_MAX.

Re: [osg-users] set render bin details

[Patrick Keenan]

Hi,

If using 

Code:

ObjStateSet->setRenderBinDetails(-1, "RenderBin");



causes that thing to be rendered first is there some trick to cause the thing 
to be drawn last? Right now I'm using

Code:

HUDStateSet->setRenderBinDetails(1000, "RenderBin");



to render my Heads Up Display last but I guess if I rendered over 1000 things 
this could fail. Is there something like

Code:

HUDStateSet->setRenderBinDetails(BIN_MAX, "RenderBin");



?

Thanks,
Patrick

Hi,

I am going through an osg example and one point there is a statement as follows:


Code:

stateset->setRenderBinDetails(-1,"RenderBin");


When OSG traverses a scene for rendering, it organizes geometry into 
separate render bins.  Each bin has an index and a sorting mode.  When 
it comes time to actually draw the geometry, the render bins are 
traversed in order of index (lowest to highest), and the geometry in 
those bins are drawn after being sorted according to the sorting mode.


In this case the index of -1 means that the geometry in this bin will be 
drawn before the rest of the geometry (which by default goes into bin 
0).  "RenderBin" is the default sort order (which happens to be 
SORT_BY_STATE).


In this case, there must be some geometry that is required to be 
rendered before the rest of the scene.  Since you didn't mention which 
osg example you were looking at, that's all I can say about it.

[osg-users] set render bin details

[Sajjadul Islam]

Hi,

I am going through an osg example and one point there is a statement as follows:


Code:

stateset->setRenderBinDetails(-1,"RenderBin");




Commenting the above statement did not make any changes to the scene.

Any explanation when one should call this function ? 

Thank you!

Cheers,
Sajjadul
