[osg-users] How to render the image without reducing its size.?

[Uma Devi Selvaraj]

Hi,

   I have simple code that renders image using osgviewer. I am able to render 
the image successfully with the code. My problem now is the size of the image 
is reduced. for example the original size of the image is 4683 * 3035, the 
image is reduced to 4096 * 3035. Is this expected behaviour or is there 
anything I need to add in my code. I have added my code.


//required header files

int main(int argc,char**argv)
{

osg::ref_ptr image;
image = osgDB::readImageFile("C:\\Users\\mcw\\Desktop\\DemModel.tif.gdal");
std::cout << "Image info are " << image->s() << "\n" setFilter(osg::Texture::MIN_FILTER, osg::Texture::LINEAR);
texture->setFilter(osg::Texture::MAG_FILTER, osg::Texture::LINEAR);
texture->setWrap(osg::Texture::WRAP_R, osg::Texture::REPEAT);
texture->setResizeNonPowerOfTwoHint(false);
texture->setImage(image);
texture->setBorderColor(osg::Vec4d(0.4f, 0.5f, 0.6f, 1.0f));
osg::StateSet* stateset = new osg::StateSet;

stateset->setTextureAttributeAndModes(0, texture, 
osg::StateAttribute::ON);

geode->setStateSet(stateset);
osgViewer::Viewer viewer;
viewer.setSceneData(geode.get());
getchar();
return viewer.run();

}

... 

Thank you!

Uma

[osg-users] calculating area of the 3d model.

[Uma Devi Selvaraj]

Hi all,

 I would like to know some information.
 
 I need to calculate area , perimeter & volume of a selected part or area 
in 3d model. For example after rendering 3d model, if I select some 
area(cloased area) , say point1 point2 point3. Point1 connected to point2 
point2 to point3, point3 connected to point1. Is it possible to do it with the 
help of OSG.?

   And how can I get longitude,latitude and altitude for the points(say 
point1).? Is there any example for this.? So that it can be helpful for me.

Do I need to build any other OSG application for this task.?  Where does the 
longitude,latitude and altitude informations are stored in 3d models 
(.3ds,.osg,.osgt)?
 


... 

Thank you!

Cheers,
Uma

OSG in another system(windows 8 , 64 bit) and tried to render same model in 
that system, where I am able to render the model in color. I have read the 
system requirements in OSG User Guide. Should I need to install latest OpenGL.? 
or What could be the problem?

[osg-users] Converting 3d Models to OSG type

[Uma Devi Selvaraj]

Hi all,

 I tried simple program to do conversion from 3d model to osg type. I 
tried to call osgconv using system() method. Here is my code.

Generalized one:
char *src = "D:/3D_Models/3D Model.obj";
char *dest = "D:/converted_Models/3D Model.osg";
  
std::cout << "converting " << std::endl;

system("osgconv src dest");

std::cout << "Completed Conversion  :)" << std::endl;

Have i done any mistake in my code. Because I am getting message saying that no 
plug in to read "src" and "dest".

If I do like this,

system("osgconv D:/3D_Models/3D_Model.obj   
D:/converted_Models/3D_Model.osg");   
 
I am able to convert. 

How will I change my code to generalize the conversion (like first method) so 
that i can get input and output from user ?.




... 

Thank you!

Uma

Hi all,
 
Regarding openthreads access violation issue,today I tried to build osg 
without(BUILD_OPENTHREADS_WITH_QT) cmake options. And I tired to use those exe 
and dll files to run my example code. I am able to render 3D model Successfully 
in both debug and release mode, the problem is it is taking too mush of time to 
render. Is there any to way to render the model quickly.
 And I just want to know use of BUILD_OPENTHREADS_WITH_QT option.? Will it 
create any issue if I build OSG without this option.?

Re: [osg-users] ot20-Openthreads.dll access violation

[Uma Devi Selvaraj]

Hi Robert,

   Just now I have installed stable release of OSG 3.4.0. I have tried with 
both Debug and Release mode. I am getting error message. I have attached it.

Re: [osg-users] Issue in Rendering Obj model using c++ code .

Hi Sebastian,
   
Do I need to build my code with release mode and linking it with 
releasewithdebuginfo library or do I need to create new configuration for my 
code in VS2013?

... 

Thank you!

[osg-users] Issue in Rendering Obj model using c++ code .

[Uma Devi Selvaraj]

Hi all,
  I have build osg version 3.4.0 in windows 8. I am able to render 3D models 
using the command "osgviewer ". 

  I have tried a simple c++ code to render 3D model. I gave .obj model as 
input. For small files (say file size of 577 KB) my code renders the given 
model successfully, whereas when my input obj model is of size 46,927 KB it 
takes long time (more than hours & not renders the model). I am facing this 
problem in debug mode.

But in Release Mode I am facing error.

My code is 



... osg::ref_ptr root;
root = osgDB::readNodeFile("D:\\3D_Models\\Concert Stage.obj");
osgViewer::Viewer viewer;
viewer.setSceneData(root.get());
return viewer.run();

I have attached the screenshot of error message.



Thank you!

Cheers,
Uma

[osg-users] Vector script out of range

[Uma Devi Selvaraj]

Hi,

I have tried a simple program in C++ to render 3d model using Osg Viewer.
When I am trying to run the code I am getting "vector script out of range error 
" for some 3d model.

This is my code.

/*osg header files */

int main(int argc,char**argv)
{


/*using ref_ptr*/
osg::ref_ptr root = osgDB::readNodeFile("bunny.ply");
osgViewer::Viewer viewer;
viewer.setSceneData(root.get());
return viewer.run();
}

can some body tell me what is the problem. but it is working for some models. I 
have attached the 3d model file. I have loaded 2963 KB file


Thank you!

Cheers,
Uma
