Hi, Pedro
Where you want show that texture?
For example, you can show that image on a square as follow, altering the
code of the file 'osgviewer.cpp':
osg::Drawable* createSquare(const osg::Vec3& corner, const osg::Vec3& width,
const osg::Vec3& height, osg::Image* image =
NULL)
{
osg::Geometry* geom = new osg::Geometry;
osg::Vec3Array* coords = new osg::Vec3Array(4);
(*coords)[0] = corner;
(*coords)[1] = corner+width;
(*coords)[2] = corner+width+height;
(*coords)[3] = corner+height;
geom->setVertexArray(coords);
osg::Vec3Array* norms = new osg::Vec3Array(1);
(*norms)[0] = width^height;
(*norms)[0].normalize();
geom->setNormalArray(norms);
geom->setNormalBinding(osg::Geometry::BIND_OVERALL);
osg::Vec2Array* tcoords = new osg::Vec2Array(4);
(*tcoords)[0].set(0.0f,0.0f);
(*tcoords)[1].set(1.0f,0.0f);
(*tcoords)[2].set(1.0f,1.0f);
(*tcoords)[3].set(0.0f,1.0f);
geom->setTexCoordArray(0,tcoords);
geom->addPrimitiveSet(new
osg::DrawArrays(osg::PrimitiveSet::QUADS,0,4));
if (image)
{
osg::StateSet* stateset = new osg::StateSet;
osg::Texture2D* texture = new osg::Texture2D;
texture->setImage(image);
stateset->setTextureAttributeAndModes(0,texture,osg::StateAttribute::ON);
geom->setStateSet(stateset);
}
return geom;
}
And then, in function 'main()',
osg::Vec3 corner(-25.f, 0.f, 0.f);
osg::Vec3 width(50.f, 0.f, 0.f);
osg::Vec3 height(0.f, 0.f, 50.f);
osg::ref_ptr<osg::Geode> geode = new osg::Geode();
geode->addDrawable( createSquare(corner, width, height,
osgDB::readImageFile("porton.tif") );
viewer.setSceneData(geode.get());
I hope this help you.
Edu
