Hi again,
I have a question about UpdateTypes and a proper way to respond to updatedObject in slotObjectUpdated. In my plugin I would like to respond to changes in an object coming from the Move plugin, from the MoveSelection in particular. The user selects vertices, transforms them using a manipulator and the plugin recomputes the position of the remaining vertices. At present I have in slotObjectUpdated something like this:
if (!type.contains(UPDATE_GEOMETRY) || PluginFunctions::pickMode() != "MoveSelection") {
return; // we are not interested and don't want to respond
}
However, any update to my object from another plugin while I am in the MoveSelection pick mode will go through. What would be the right way to go about this?
A related question: why for example clearModelingArea from Plugin-SelectionMeshObject emits UPDATE_ALL if it does not modify geometry or topology of the object?
Another related question: if I add a property to an object, I would like to notify other plugins about it (e.g., PropertyVis). How would I do it?
Thanks a lot for your help,
Vladimir
Dear Möbius,
I would like to ask about giving colors to the edges and visualizing them
on the Openflipper visualization framework.
Here is my code, but I cannot see the colored edges;
m_mesh->request_edge_colors();
m_mesh->set_color(m_mesh->edge_handle(0), PolyMesh::Color(0, 255, 0));
PluginFunctions::setDrawMode(ACG::SceneGraph::DrawModes::EDGES_COLORED);
emit updatedObject(m_targetObject->id(), UPDATE_COLOR);
Thank you.

Hi!
I was trying to export a TriMesh to the PLY file format with vertex colors.
The mesh looks as expected in OpenFlipper. But the exported mesh was all
black in MeshLab. When looking at the PLY file, the components of the
colors were all either 0 or 1.
I believe there is a bug in the PLY exporter. TriTraits::Color is
defined as Vec4f. FilePLYT.cc exports this as
ofs << " " << OpenMesh::color_cast<OpenMesh::Vec3i>(c);
That means, that in fact OpenMesh::color_coder<Vec3i, Vec4f> is used for
the conversion. Since there is no such specialization of color_coder,
the default template will be used, which just converts to int. Thus, the
resulting colors will all be not correct.
Shouldn't it be this?
ofs << " " << OpenMesh::color_cast<OpenMesh::Vec3uc>(c);
Bye,
Bengt
Dear openflipper,
Last time, we raised Vol 29, Issue 5.
According to your suggestion,
we chagned code to :
*int intObjectID = PluginFunctions::getObjectId(strPrameterizationObjectName);
PluginFunctions::setDrawMode(ACG::SceneGraph::DrawModes::POINTS_SHADED, 1);
emit updatedObject(intObjectID, UPDATE_COLOR );*/
Unfortunately, I found that it did not work. The color did not show up.
Besides, we have a new problem with the code below.
Compiling and running the following are fine. The problem is line 1 works
fine, but line 2 give no message in the status bar.
Line1:
QMessageBox::information(NULL, "Scene Position", string,
QMessageBox::Yes, QMessageBox::Yes);
Line2: emit showStatusMessage(string, 100);
Thank for your help!
THANKS VERY MUCH FOR YOUR GREAT WORK!!
Regards,

Hi,
OpenFlipper 1.3 has been released. This release adds some new
functionality.
The poly line has been added as a new data type. It can be moved across
a surface, and has build in algorithms for smoothing, decimation and
subdivision.
The ruler plugin is now available and can be used to measure the
euclidean distance between objects in the 3D scene.
The subdivider has been extended by a Catmull-Clark algorithm for
QuadMeshes and various other plugins got improvements or bugfixes.
Furthermore there were various updates for gcc-4.7 compatibility and
documentation improvements.
For a full list of changes please look into the changelog.
http://openflipper.org/Documentation/OpenFlipper-1.3/changelog.html
Best,
Jan Möbius

Hi,
I've tried using:
emit updatedObject(-1, UPDATE_ALL)
after performing an operation that updates a number of objects within in
the scene.
The documentation implies that this should call updatedObject for all
objects, it doesn't seem to work. I'm currently using OpenFlipper 1.2, but
I don't see a mention of this in the changelog for 1.3.

Hi,
i want to write a shader, that sums up all values of a vertexproperty
for all visible vertices and one with which i compute the color for
each vertex using a vertexproperty. Are vertexproperties being pushed
automatically into the pipeline or do i have to assign them manually?
If necessary what needs to be done so that a shader can use a property
and how can i access that property in my vertex shader. I already
thought about a workaround, storing the property value for a vertex in
a texture but is there a better way?
Best Regards

Dear OpenFlipper,
We really appreciate your feedback in such a quick time!!
Now, by following your instruction, both the compiling and running are fine without error pop-up.
Here is our code:
_mesh->set_color(_mesh->vertex_handle(intLoopBeginningVertexHandle), TriMesh::Color(0.7,0.286,0.5568,1.0));
HOWEVER, we found that the vertex color of mesh in viewport did not change at all.
It was still in red(selection status).
In code, we would like to change the color of those vertices which formed a boundary of a region.
Could you please share us with your idea?

Dear Openflipper,
Currently, we encountered error while calling set_color command.
Here is our code line:
for(std::vector<int>::iterator iterAvi = verticeInSelection_.begin();
iterAvi != verticeInSelection_.end();
++iterAvi)
{
for(TriMesh::VertexVertexIter vv_it = _mesh->vv_iter(_mesh->vertex_handle(*iterAvi)); vv_it; ++vv_it)
{
if(!_mesh->status(vv_it).selected())
{
//_mesh->set_color(_mesh->vertex_handle(*iterAvi), TriMesh::Color(250, 0, 160));
vecBoundary_.push_back(*iterAvi);
break;
}
}
}
Could you kindly give us your suggestion?

Dear Openflipper,
In code, we are able to call the following instruction to switch the view mode from single to double.
RPC::callFunction("core", "MultiViewMode", 1);
However, I found that the combo of "Switch viewer layout" in the toolbar did not change.
It was still in the first item.
How could I change it in code?
Best Regards,
Xianyong Liu.

Hi,
OpenFlipper uses Vec4f as it's color format. So Your colors should be
defined as RGBA (range 0 ... 1 per component).
TriMesh::Color(1.0, 0.0, 0.0 ,1.0));
If that does not work, please send me the error produced by the compiler.
