[osg-users] 3D texture

[George Forest]

Hi,

I have a 3DS model. How can I add tihs model as done in 2D images with Geode 
and Geometry. This code adds 2D objects. What modifications should I make on it?

ref_ptr<Geode> geode(new Geode());
                ref_ptr<Geometry> geometry(new Geometry());
                
                ref_ptr<Vec3Array> vertices(new Vec3Array());
                
                vertices->push_back(Vec3(objectPosition[0], objectPosition[1], 
objectZCoordinate));
                vertices->push_back(Vec3(objectPosition[2], objectPosition[1], 
objectZCoordinate));
                vertices->push_back(Vec3(objectPosition[2], objectPosition[3], 
objectZCoordinate));
                vertices->push_back(Vec3(objectPosition[0], objectPosition[3], 
objectZCoordinate));

                geometry->setVertexArray(vertices.get());

            ref_ptr<Vec4Array> colors(new Vec4Array());
            colors->push_back(Vec4(1.0f, 1.0f, 1.0f, 1.0f));
            geometry->setColorArray(colors.get());
            geometry->setColorBinding(Geometry::BIND_OVERALL);

            ref_ptr<Vec3Array> normals(new Vec3Array());

            normals->push_back (Vec3(0.0f, -1.0f, 0.0f));
            geometry->setNormalArray(normals.get());
            geometry->setNormalBinding(Geometry::BIND_OVERALL);

            ref_ptr<Image> image(readImageFile(objectPath));

            ref_ptr<Texture2D> texture(new Texture2D);
            texture->setImage(image.get());

            ref_ptr<StateSet> stateSet(geode->getOrCreateStateSet());
            stateSet->setTextureAttributeAndModes (0, texture.get(), 
StateAttribute::ON);

            ref_ptr<Vec2Array> texCoords(new Vec2Array());

            texCoords->push_back(Vec2(0.0, 0.0));
            texCoords->push_back(Vec2(0.0, 1.0));
            texCoords->push_back(Vec2(1.0, 1.0));
            texCoords->push_back(Vec2(1.0, 0.0));

            geometry->setTexCoordArray(0, texCoords.get());

            geometry->addPrimitiveSet(new DrawArrays(PrimitiveSet::QUADS, 0, 
vertices->size()));

            geode->addDrawable(geometry.get());

            return geode;


Thank you!

Cheers,
George
