Re: [osg-users] RegisterRenderBinProxy with OSG 3
Hi,
Thanks for the hint, but I tried that already, it gives me a
C2761: 'void osgUtil::RenderBin::addRenderBinPrototype(const std::string
,osgUtil::RenderBin *)' : member function redeclaration not allowed
The code which I want to replace is outside a class, like this:
Code:
#include ...
#include ...
#include ...
using namespace osgHaptics;
osgUtil::RenderBin::addRenderBinPrototype(HapticRenderBin,new
HapticRenderBin);
HapticRenderBin::HapticRenderBin(SortMode mode) : RenderBin(mode),
m_last_frame(-1)
{
}
...
Is the new addRenderBinPrototype only usable inside a function?
Thank you!
Cheers,
Bob

Re: [osg-users] RegisterRenderBinProxy with OSG 3
Hi Bob,
osgUtil::RenderBin::addRenderBinPrototype() is static member function call,
so you just call it with the body of your initialization code. You could
do this within a proxy object if you wished to keep the implementation
similar to what you've used before.
Robert.

You'll want to register your RenderBin prototype prior to running the first cull traversal as this will be the first type that the RenderBin will be looked up and cloned.

[osg-users] indexing model - loss of data
Hi all
once i've wrote small utility to optimize models with rig geometry, which,
among other things, apply INDEX_MESH, VERTEX_PRETRANSFORM, VERTEX_POSTTRANSFORM
optimizations and remaps vertex influences of rig geometry to new vertex
indices. Now it suddenly dont work any more.
Problem is that after indexing geometry, there are not enough matches between
old vertex attributes and new vertex attributes (some old vertex attribute
values cant be found in new vertex attribute arrays after indexing, which means
some data is lost).
here is some simplified code to show problem:
//
template typename T bool compare(T* r, unsigned ri, T* l, unsigned li)
//compares two array elements
{
if ((*r)[ri] (*l)[li])
return false;
if ((*l)[li] (*r)[ri])
return false;
return true;
}
bool cmp (osg::Geometry::ArrayList rhs, unsigned rhsi,
osg::Geometry::ArrayList lhs, unsigned lhsi) //compares all [rhsi] elements
from rhs array list with all [lhsi] elements in lhs array list
{
if (rhs.size() != lhs.size())
throw std::logic_error(different vertex attrib arrays count
before and after optimizations, cant do anything);
bool result = true;
for (unsigned i = 0; i rhs.size(); i++)
{
bool compared = false;
if (!result)
return result;
{
osg::Vec3Array* r =
dynamic_castosg::Vec3Array*(rhs[i]);
osg::Vec3Array* l =
dynamic_castosg::Vec3Array*(lhs[i]);
if (r l)
{
result = result compare(r, rhsi, l, lhsi);
compared = true;
}
}
{
osg::Vec2Array* r =
dynamic_castosg::Vec2Array*(rhs[i]);
osg::Vec2Array* l =
dynamic_castosg::Vec2Array*(lhs[i]);
if (r l)
{
result = result compare(r, rhsi, l, lhsi);
compared = true;
}
}
if (!compared)
return false;
}
return result;
}
void acceptMesh(osgAnimation::RigGeometry* rg)
{
osg::Geometry* g = rg-getSourceGeometry();
osg::ref_ptrosg::Geometry origG = new osg::Geometry(*g,
osg::CopyOp::DEEP_COPY_ALL);
osg::Geometry::ArrayList alold;
origG-getArrayList(alold);
osg::ref_ptrosg::Vec3Array origVerts =
dynamic_castosg::Vec3Array*(origG-getVertexArray());
osgUtil::IndexMeshVisitor imv;
imv.makeMesh(*g);
osg::Geometry::ArrayList alnew;
g-getArrayList(alnew);
std::mapint, int vertsMap;//store matches between old and new
vertexattrib arrays in pairs [old_index, new_index]
osg::ref_ptrosg::Vec3Array newVerts =
dynamic_castosg::Vec3Array*(g-getVertexArray());
unsigned id = 0;
for (osg::Vec3Array::iterator itr = origVerts-begin(); itr !=
origVerts-end(); itr++)
{
unsigned nid = 0;
for (osg::Vec3Array::iterator itr2 = newVerts-begin();
itr2 != newVerts-end(); itr2++)
{
if (cmp(alold, id, alnew, nid))//found match
{
vertsMap[id] = nid;
break;
}
nid++;
}
id++;
}
std::cerrorigVerts size:origVerts-size()std::endl;
std::cerrverts map size:vertsMap.size()std::endl;
}
/
here size of vertsMap map should be same as original vertex count, and it isnt,
which means some data is lost when indexing geometry (and comparing floating
point values with thresholds does not change anything, i've tested it).
Any ideas about what could go wrong? May be there was some changes to the way
IndexMeshVisitor works? I'm testing on osg svn version updated last week or so.
Cheers,
Sergey.

Hi Chris, It is my understanding that AMD cards won't frame-lock without the S400 card you might be correct, but you mentioned, that rendering in not very demanding, thus setting VSync might be enough to soft-frame-lock on powerful card ( which should be oders of magnitude more powerful than old Matrox cards ) Regards Sergey ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi yes, it's doing just that, but it written in a way to keep duplicate vertices with same position if other vertex attributes for this vertex is different.

Problem is that after indexing geometry, there are not enough matches between old vertex attributes and new vertex attributes (some old vertex attribute values cant be found in new vertex attribute arrays after indexing, which means some data is lost). here is some simplified code to show problem: // template typename T bool compare(T* r, unsigned ri, T* l, unsigned li) //compares two array elements { if ((*r)[ri] (*l)[li]) return false; if ((*l)[li] (*r)[ri]) return false; return true; } bool cmp (osg::Geometry::ArrayList rhs, unsigned rhsi, osg::Geometry::ArrayList lhs, unsigned lhsi) //compares all [rhsi] elements from rhs array list with all [lhsi] elements in lhs array list { if (rhs.size() != lhs.size()) throw std::logic_error("different vertex attrib arrays count before and after optimizations, cant do anything"); bool result = true; for (unsigned i = 0; i rhs.size(); i++) { bool compared = false; if (!result) return result; { osg::Vec3Array* r = dynamic_castosg::Vec3Array*(rhs[i]); osg::Vec3Array* l = dynamic_castosg::Vec3Array*(lhs[i]); if (r l) { result = result compare(r, rhsi, l, lhsi); compared = true; } } { osg::Vec2Array* r = dynamic_castosg::Vec2Array*(rhs[i]); osg::Vec2Array* l = dynamic_castosg::Vec2Array*(lhs[i]); if (r l) { result = result compare(r, rhsi, l, lhsi); compared = true; } } if (!compared) return false; } return result; } void acceptMesh(osgAnimation::RigGeometry* rg) { osg::Geometry* g = rg-getSourceGeometry(); osg::ref_ptrosg::Geometry origG = new osg::Geometry(*g, osg::CopyOp::DEEP_COPY_ALL); osg::Geometry::ArrayList alold; origG-getArrayList(alold); osg::ref_ptrosg::Vec3Array origVerts = dynamic_castosg::Vec3Array*(origG-getVertexArray()); osgUtil::IndexMeshVisitor imv; imv.makeMesh(*g); osg::Geometry::ArrayList alnew; g-getArrayList(alnew); std::mapint, int vertsMap;//store matches between old and new vertexattrib arrays in pairs [old_index, new_index] osg::ref_ptrosg::Vec3Array newVerts = dynamic_castosg::Vec3Array*(g-getVertexArray()); unsigned id = 0; for (osg::Vec3Array::iterator itr = origVerts-begin(); itr != origVerts-end(); itr++) { unsigned nid = 0; for (osg::Vec3Array::iterator itr2 = newVerts-begin(); itr2 != newVerts-end(); itr2++) { if (cmp(alold, id, alnew, nid))//found match { vertsMap[id] = nid; break; } nid++; } id++; } std::cerr"origVerts size:"origVerts-size()std::endl; std::cerr"verts map size:"vertsMap.size()std::endl; } / here size of vertsMap map should be same as original vertex count, and it isnt, which means some data is lost when indexing geometry (and comparing floating point values with thresholds does not change anything, i've tested it). Any ideas about what could go wrong? May be there was some changes to the way IndexMeshVisitor works? I'm
Re: [osg-users] Order Independent Transparancy with Per-Pixel-Linked-Lists
Hi, after reading some of the commit messages it looks like not all necessary api methods are integrated in OpenSceneGraph right now. glMemoryBarrier for example is not called anywhere but necessary to make sure all data is written to the image before starting the next rendering stage. So my next step will be to first implement the technique with pure OpenGL and then see how I can integrate it in OpenSceneGraph. Thank you!
