[osg-users] problem with cessna texturing

[Vadim Balashoff]

here is my code:

Code:

#include <stdio.h>

#include <osg/Geometry>
#include <osg/Geode>
#include <osg/Material>
#include <osg/ShapeDrawable>
#include <osg/Texture2D>
#include <osgDB/ReadFile>
#include <osgUtil/SmoothingVisitor>
#include <osgViewer/Viewer>

int main ()
{

    osg::Material *material = new osg::Material();
    material->setEmission(osg::Material::FRONT, osg::Vec4(0.8, 0.8, 0.8, 1.0));

    osg::Image* image = osgDB::readImageFile("FD_image.jpg");
    if (!image) {
        std::cout << "Couldn't load texture." << std::endl;
        return -1;
    }
    osg::Texture2D *texture = new osg::Texture2D;
    texture->setDataVariance(osg::Object::DYNAMIC);
    texture->setFilter(osg::Texture2D::MIN_FILTER, osg::Texture2D::LINEAR);
    texture->setFilter(osg::Texture2D::MAG_FILTER, osg::Texture2D::LINEAR);
    texture->setWrap(osg::Texture2D::WRAP_S, osg::Texture2D::MIRROR);
    texture->setWrap(osg::Texture2D::WRAP_T, osg::Texture2D::MIRROR);
    texture->setWrap(osg::Texture2D::WRAP_R, osg::Texture2D::MIRROR);
    texture->setImage(image);

    osg::ref_ptr<osg::Node> plane = osgDB::readNodeFile( "cessna.osg" );

    osg::StateSet *planeStateSet = plane->getOrCreateStateSet();
    planeStateSet->ref();
    planeStateSet->setAttribute(material);
    planeStateSet->setTextureAttributeAndModes(0, texture, osg::StateAttribute::OVERRIDE);

    planeStateSet->setTextureMode(0, GL_TEXTURE_2D,osg::StateAttribute::ON|osg::StateAttribute::OVERRIDE);
    planeStateSet->setTextureMode(0, GL_TEXTURE_GEN_S,osg::StateAttribute::ON|osg::StateAttribute::OVERRIDE);
    planeStateSet->setTextureMode(0, GL_TEXTURE_GEN_R,osg::StateAttribute::ON|osg::StateAttribute::OVERRIDE);
    planeStateSet->setTextureMode(0, GL_TEXTURE_GEN_T,osg::StateAttribute::ON|osg::StateAttribute::OVERRIDE);
    planeStateSet->setAttribute(material, osg::StateAttribute::OVERRIDE);

    planeStateSet->setMode( GL_RESCALE_NORMAL, osg::StateAttribute::ON );
    planeStateSet->setMode( GL_NORMALIZE, osg::StateAttribute::ON );

    osgViewer::Viewer viewer;
    viewer.setSceneData( plane );
    return viewer.run();

};
