Re: [osg-users] geometry shader with opengles
Hi,
I have succeeded on Android ,But not well on IOS,whether it is iphone4 or 6p or

they all show: version '310' is not supported

But version 300 is OK(but couldn't use geometry shader),So is there somthing i

That's based on my recollection before using proper callbacks. The former is probably a quick way to get things working. The latter is probably better in the long run once you're comfortable with various concepts in OSG.

[osg-users] DrawImplementation issue with Intel video card.
Hi,
I meet a problem in function drawImplementation(osg::RenderInfo renderInfo)
const
Actually the code works find with nvidia and ati video card, just when I run it
in intel 965GM, it get problem.
Here is the code:
void SubmeshDrawable::drawImplementation(osg::RenderInfo renderInfo) const
{
osg::State state = *renderInfo.getState();
//bind the VBO's
state.disableAllVertexArrays();
bool initializedThisDraw = false;
if (!mInitalized)
{
InitVertexBuffers(state);
mInitalized = true;
initializedThisDraw = true;
}
-
// notice when first time run, then mInitalized is assigned as true, and it
keeps as true in nvidia or ati video card.
// But in Intel card, the value of mInitalized will change back to false again
when enter the function at second time, and keep in this way until the VBO
crashed.
Any reason for that?
Thanks a lot.

[osg-users] problem of traverse two layer groups
Hi,
The nodevisitor seems cannot reach the leaf node when I add two layers of
groups. like this:
root (group)
/ | \
group ... group
/ | \
geode.
my code is like this, basiclly this is the example of texture2D example:
virtual void apply(osg::Geode geode)
{
apply(geode.getStateSet());
for(unsigned int i=0;igeode.getNumDrawables();++i)
{
apply(geode.getDrawable(i)-getStateSet());
}
traverse(geode);
}
//
virtual void apply(osg::Group group)
{
apply(group.getStateSet());
for(unsigned int i = 0; i group.getNumChildren(); ++i)
{
apply(*(group.getChild(i))); // here is the code for group maybe get
trouble.
}
traverse(group);
}
/
virtual void apply(osg::Node node)
{
apply((osg::Geode )(node)); // this is nothing.
apply(node.getStateSet());
traverse(node);
}
inline void apply(osg::StateSet* stateset)
{
if (!stateset) return;
osg::StateAttribute* attr =
stateset-getTextureAttribute(0,osg::StateAttribute::TEXTURE);
if (attr)
{
osg::Texture2D* texture2D = dynamic_castosg::Texture2D*(attr);
if (texture2D) apply(dynamic_castosg::ImageStream*(texture2D-getImage()));
osg::TextureRectangle* textureRec = dynamic_castosg::TextureRectangle*(attr);
if (textureRec) apply(dynamic_castosg::ImageStream*(textureRec-getImage()));
}
}
// and when create scene as:
osg::Node* createZYloadWall(osg::BoundingBox bb)
{
// then the original code use a group then add geode by addchild
// then return the first layer group.
// osg::Group* group = new osg::Group;
osg::Geometry* geom = new osg::Geometry;
osg::Geode* geom_geode = new osg::Geode;
geom_geode-addDrawable(geom);
// group-addChild(geom);
return geom_geode;
//return group;
}
// then later add another layer of root.
{
osg::Group* root = new osg::Group();
root-addchild(createZYloadWall(osg::BoundingBox bb));
}
// the problem is that if do it with two layer group, the nodevisitor still can
go to geod
by code:
virtual void apply(osg::Group group)
{
apply(group.getStateSet());
for(unsigned int i = 0; i group.getNumChildren(); ++i)
{
apply(*(group.getChild(i))); // here is the code for group maybe get
trouble.
traverse(group);
}
// but the geode looks not right.
I finally remove one group layer then directly add geode into root,
then it works,
So my question is how to traverse with two layer of group, is my code right?
Thanks.
