[osg-users] OpenGL warning

[Qiaokun Lefei]

Hi,

I always come across this warning "Warning: detected OpenGL error 'invalid 
operation' after RenderBin::draw(..)" in my osg project. Mybe it's just the 
problem of the driver. I want to know how to make this warning disappear or 
just shield it.


Thank you!

Cheers,
Qiaokun

Re: [osg-users] Dimension Mask in PolytopeIntersector still working?

[Jordi Torres]

Hi Robert,

I'm ok to change the name. My concern was more about losing functionality.

Thank you!

[osg-users] draw primitive sets and geometry shader in opengl 3

[Werner Modenbach]

I have a simple question but couldn't find an answer.

My geode is assigned a geometry shader that starts with

layout(lines_adjacency)in;
 


For drawing geometry 1 I use
geometry1->addPrimitiveSet(newosg::DrawArrays(osg::PrimitiveSet::LINE_STRIP_ADJACENCY,0,count)); 



That works absolutely fine.

For drawing geometry 2 in the same geode I use
geometry2->addPrimitiveSet(newosg::DrawArrays(osg::PrimitiveSet::TRIANGLE_FAN,0,count)); 



Is the geometry shader just skipped for the second geometry? Or must I 
assign an individual shader for each geometry?

This might be a big slowdown because I have really many of those geodes.
Is it possible to define 2 geometry shaders with different layouts in 
one shader program?


Thanks for any hints.

I have just checked in support for PolytopeIntersect::DimensionMask.
I haven't change the name but I think it really should be called
PrimitiveMask as this would be more appropriate.

It used to work meaning that one could target only lines, or points, or
triangles or a combination of them. Now that seems not possible.

Also I'm getting repeated intersection points for some intersections, but I
need to test it further.

I'll keep you posted.

I vaguely recall seeing the dimensionMask  code in the original
PolytopeIntersector and it struck me as a bit hacky, perhaps I didn't
get round to implementing in the new code.

Re: [osg-users] Get RenderBinDetails

[Robert Osfield]

Hi Bruno,

>From the include/osg/StateSet header:

/** Set the render bin details.*/
void setRenderBinDetails(int binNum,const std::string&
binName,RenderBinMode mode=USE_RENDERBIN_DETAILS);

...

/** Set the render bin number.*/
inline void setBinNumber(int num) { _binNum=num; }

/** Get the render bin number.*/
inline int getBinNumber() const { return _binNum; }

[osg-users] Dimension Mask in PolytopeIntersector still working?

[Jordi Torres]

Hi Robert,

With your last changes about Polytope Intersection I'm not sure wether
dimensionmask is still used. A quick grep does not reveal any use of
_dimensionMask in the intersection proccess or getDimensionMask method in
PolytopeIntersector.

Am I missing something?

[osg-users] Get RenderBinDetails

[Bruno Oliveira]

Hello,

in order to sort my nodes by depth, I use the following code to a node's
stateset

nodeStateSet->setRenderBinDetails(order, "DepthSortedBin");

where "order" is an int. Now, how do I get that value when I'm iterating
over my nodes?
