[osg-users] How to build osgdotnet wrapper for OpenSceneGraph-3.0.0
Hi List, I am trying to build osgdotnet warpper for OpenSceneGraph-3.0.0. I have read the document provided here and i have compiled generator .sln aslo. http://www.openscenegraph.org/projects/osgDotNet/wiki/GettingStartedWithTheWrappersGenerator But i have read in archive mail that we need to modify osgdotnet wrapper to work for OpenSceneGraph-3.0.0. Is it correct? If some body already done this for OpenSceneGraph-3.0.0 or any new version . Plaese guide me or even any link will be welcome Thank you!

Code is perfect just we need to initialize uniform properly -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=31530#31530 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] How to pass materail color of 3ds through shader using OpenGL ES 2.0
Hi List,
Thanks for all the support.Now I am able to build Osg with opengl ES 2.0
without Qt and can run the sample programs.
I am able to load the .3ds file but I am unable to render the correct material
on the screen.
Following is the source code I m using:
Code:
#include
#include
#include
#include
#include
#include
#include
#include
//#include
#include
using namespace osg;
osg::Uniform* _ClrUniform;
static const char* vertSource = {
"// colors a fragment based on its position\n"
"uniform vec3 color; \n"
"varying mediump vec4 Finalcolor;\n"
"void main(void) {\n"
"Finalcolor = color;\n"
"gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;\n"
"}\n"
};
static const char* fragSource = {
//SHADER_COMPAT
"varying mediump vec4 Finalcolor;\n"
"void main(void) {\n"
"gl_FragColor = Finalcolor;\n"
"}\n"
};
int main( int, char ** )
{
osgViewer::Viewer viewer;
osg::setNotifyLevel(osg::INFO);
ref_ptr m_root = new Group;
osg::Geode* geode = (osg::Geode* )osgDB::readNodeFile( "info_icon.3ds" );
osg::Program* program = new osg::Program;
program->setName("shader");
program->addShader(new osg::Shader(osg::Shader::VERTEX, vertSource));
program->addShader(new osg::Shader(osg::Shader::FRAGMENT, fragSource));
geode->getOrCreateStateSet()->setAttributeAndModes(program,
osg::StateAttribute::ON);
_ClrUniform = new osg::Uniform("color",osg::Vec3(1.0,0.0,0.0));//Initializing
the uniform
osg::StateSet *stateSet = geode->getOrCreateStateSet();
stateSet->addUniform(_ClrUniform);
stateSet->setMode(GL_BLEND, osg::StateAttribute::ON);
m_root->addChild(geode);
viewer.setUpViewInWindow( 32, 32, 1024, 600 );
viewer.setSceneData(m_root.get());
return viewer.run();
}
I have looked at material.cpp and tried to set the Uniform for material.But
somehow its not updating in the application.It is taking black color by default.
I think that, they have not handled the material property for ES 2.0 in
material.cpp
I have tried modifying the code in material.cpp in void
Material::apply(State&) const function.
The modified code is as follows:
Code:
osg::Uniform* _myClrUniform;
_myClrUniform->set( osg::Vec3(_diffuseFront.x(), _diffuseFront.y(),
_diffuseFront.z()) );
How can I set the material property of every object through application for
.3DS file?
Any help will be appreciated.
Regards,
Parmar
