What do you mean by models in this context? What have the vertex position have to do with the "models"? Normally with scene graph usage a "model" would represent something like a car, a house, or a whole town etc, and would be loaded/created as a subgraph that gets added to the overall scene. With each of these subgraphs you can attach a StateSet to the topmost of node of the subgrah, and have thes StateSet provide a specific Uniform value that can control shaders. Whether this is at all appropriate in your case I cannot say as I can't work out what you might mean.

If you build it against GLES2 then you need to add your own shaders to see something on screen, of course the example for GLES2 won't work if OSG was built with GLES1 and the GLES1 example won't show anything if OSG was compiled with GLES2, I apologize if this was already clarified :) > > Best regards, > Rafa. > > > Then how do I use the toolchain file for compiling examples that are imported in Eclipse ?

Re: [osg-users] AnimationPath + AnimationPathCallback
I forgot to mention: I use openscenegraph 3.2.1 on Linux. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=63520#63520 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] AnimationPath + AnimationPathCallback
Hi,
right now i try to move to different objects in my scene. I attached a own
AnimamationPathCallback to 2 MatrixTransform Nodes in my scene.
My goal is, that both nodes move independently but each should notify me, when
it animation is finished.
Here is my callback
Code:
// create the update callback
struct Notify : osg::AnimationPathCallback
{
Notify(osg::AnimationPath* p, bool& animation_done)
: osg::AnimationPathCallback(p) , m_animation_done(animation_done) {}
virtual void operator()(osg::Node* node,
osg::NodeVisitor* nv)
{
osg::AnimationPathCallback::operator()(node,nv);
if (m_animation_done)
return;
osg::MatrixTransform* p_mt =
dynamic_cast(node);
if (p_mt)
{
auto p_down = dynamic_cast(p_mt->getUpdateCallback());
if (p_down == this)
{
auto p_path = getAnimationPath();
double current_time = getAnimationTime();
double max_time = p_path->getLastTime();
if (current_time >= max_time)
{
m_animation_done = true;
}
}
}
}
bool& m_animation_done;
};
This callback works when only one is attached to a node in the scene. When i
attach two of them, with different animation path, just the one of them gets
updated. In fact, i bought both OpenSceneGraph Books, but i could not find a
hint why this should not happen.
This way i start the animations
Code:
void update_controller::start_animation(const std::vector& animation,
bool& animation_done)
{
animation_done = false;
osg::ref_ptr p_path =
new osg::AnimationPath;
// only one shot
p_path->setLoopMode(osg::AnimationPath::NO_LOOPING);
// define the control points
assert(animation.size() >= 2);
static const osg::Vec3 delta_z( 0, 0, 1 );
size_t p = 0; float time = 0.0f;
osg::AnimationPath::ControlPoint cp(m_all_pos[animation[p]]);
p_path->insert(time, cp); time+= 0.1f;
cp = osg::AnimationPath::ControlPoint(m_all_pos[animation[p]] - delta_z);
p_path->insert(time, cp); time+= 0.1f;
p++;
assert(p == 1);
while (p < animation.size()-1)
{
cp = osg::AnimationPath::ControlPoint(m_all_pos[animation[p]] -
delta_z);
p_path->insert(time, cp); time+= 0.1f;
p++;
}
cp = osg::AnimationPath::ControlPoint(m_all_pos[animation[p]]);
p_path->insert(time, cp); time+= 0.1f;
osg::ref_ptr p_animation_cb =
new Notify(p_path.get(), animation_done );
// set this callback to the desired pins matrix
assert(m_id_player_pin != -1);
assert(m_pins[m_id_player_pin] != nullptr);
m_pins[m_id_player_pin]->setUpdateCallback(p_animation_cb.get());
}
I guess, it is just a small thing. This is my first OSG project and in fact it
is my first problem, which i cant solve by reading the books :(
Thank you!
Cheers,
Georg

Hi Hi,
so, I downloaded osgAndroid, imported the projects into my Eclipse. I
like this more elegant way of jni-wrapping - comes close to what I've
seen in OpenCV when compiling it for mobile.
Then, I needed to rebuild the OpenSceneGraph 3.3.7, because
osgAndroid's README.md says "only working with GLES 1.1 builds".
okay, said - executed. I get the following errors already common
to me when building OSG GLES 1.1:
