[osg-users] Regarding Lod problem in osg
Hi,Iam loading the terrain with buildings,trees,roads etc using lod (level of detail ) in run time using osg. Buildings - Reading from shapefile,textures,xml file ,iam able to placing in the terrain using vpb tool. Roads - same process as buildings loaded. terrain - using imagery(image tiles) and elevation files again using vpb tool. What my problem is upon launching the application buildings,road etc taking much time to appear on the screen,how can i load buildings,road etc instantly(immediately) using lod concept (at run time) in osg ? Iam using osg 3.4.0 version,windows 8.1,vpb tool. Any Help is Appreciated. ... Thank you!

Re: [osg-users] Related to osg lines
Hi, Iam using the following code and drawing the lines in osg and clamping the
lines to the terrain for the purpose of road drawing
LineSymbol* line = style.getOrCreate();
line->stroke()->color() = Color(Color::Black, 0.5f);
line->stroke()->width() = 8.0f;
line->tessellationSize() = 5;
line->stroke()->widthUnits() = Units::METERS;
AltitudeSymbol* alt = style.getOrCreate();
alt->clamping() = alt->CLAMP_TO_TERRAIN;
But for me i want road with texture so what iam
adding the quad and applying texture in the below code
osg::ref_ptr vertices = new osg::Vec3Array;
vertices->push_back(osg::Vec3(-1.0f,0.0f,-2.0f));
vertices->push_back(osg::Vec3(1.0f,0.0f,-2.0f));
vertices->push_back(osg::Vec3(1.0f,0.0f,2.0f));
vertices->push_back(osg::Vec3(-1.0f,0.0f,2.0f));
osg::ref_ptr normals = new osg::Vec3Array;
normals->push_back(osg::Vec3(0.0f,-1.0f,0.0f));
osg::ref_ptr colors = new osg::Vec4Array;
colors->push_back(osg::Vec4(0.0f, 0.0f, 0.0f,0.0f));
osg::ref_ptr texcoords = new osg::Vec2Array;
texcoords->push_back(osg::Vec2(0.0f, 0.0f));
texcoords->push_back(osg::Vec2(0.0f, 1.0f));
texcoords->push_back(osg::Vec2(1.0f, 1.0f));
texcoords->push_back(osg::Vec2(1.0f, 0.0f));
osg::ref_ptr geom = new osg::Geometry;
geom->setVertexArray(vertices.get());
geom->setNormalArray(normals.get());
geom->setColorArray(colors.get());
geom->setNormalBinding(osg::Geometry::BIND_OVERALL);
geom->setTexCoordArray(0,texcoords.get());
geom->setColorBinding(osg::Geometry::BIND_OVERALL);
geom->addPrimitiveSet(new osg::DrawArrays(GL_QUADS,0,4));
osg::ref_ptr texture = new osg::Texture2D;
texture->setWrap(osg::Texture2D::WRAP_S,
osg::Texture2D::CLAMP);
texture->setWrap(osg::Texture2D::WRAP_T,
osg::Texture2D::CLAMP);
osg::ref_ptr image =
osgDB::readImageFile("D:/Images/roadPic.jpg");
texture->setImage(image);
osg::ref_ptr root = new osg::Geode;
root->addDrawable(geom.get());
root->getOrCreateStateSet()->setTextureAttributeAndModes(0,texture.get());
how to clamp the quad to the terrain for drawing the road in osgearth or any
other way to add the texture to those lines?
...
Thank you!

Re: [osg-users] Detail Texture
Hi,Hi,Here we can add texture image by using imageoverlay function i posted the
code below it explains all about it.
#include
osg::ref_ptr root = new osg::Group;
ImageOverlay *imageoverlay = NULL;
osg::ref_ptr image = osgDB::readImageFile("Indiaimage.jpg");
imageoverlay = new ImageOverlay(mapNode, image);
imageoverlay->setBounds(Bounds(74.56, 26.21, 77.12, 28.36));
root->addChild(imageoverlay);
Detail texture file is not there in osg earth ? Hope this provide the required
image on the osgearth with latitude,longitude readings.
