image gone in some position [SOLVED]

hi, i load an image using Material
the image is :
1. time in right - top
2. speedometer in right - bottom

it's work like this
the car position is (58.5801, 0.605723, 53.6801)


but if the car position in (147.566, 0.739556, 103.042) the image gone like this


i already use setWorldSize(Vector3(-100000,-100000,-100000), Vector3(100000,100000,100000));
how to show the image in every area in the world?
thx

How are those "images" loaded or created in your application, are they overlays or a plane mesh?

You can use overlays to have a 2d image that is part of your user interface (similar to the Ogre debug overlays)

If they are a plane positionated in front of the camera, you can link them to the camera and they will matain their position in front of the camera as you move it


MaterialPtr material = MaterialManager::getSingleton().create("Background", "General");
material->getTechnique(0)->getPass(0)->createTextureUnitState("speedometer.png");

material->getTechnique(0)->getPass(0)->setSceneBlending(SBT_TRANSPARENT_ALPHA );
material->getTechnique(0)->getPass(0)->setDepthCheckEnabled(false);
material->getTechnique(0)->getPass(0)->setDepthWriteEnabled(false);
material->getTechnique(0)->getPass(0)->setLightingEnabled(false);

Rectangle2D* rect = new Rectangle2D(true);
Real L = -0.375;
Real R = L + 0.75;
Real T = -0.12;
Real B = T - 1.0;
rect->setCorners(L, T, R, B);
rect->setMaterial("Background");

rect->setRenderQueueGroup(RENDER_QUEUE_WORLD_GEOMETRY_1);
rect->setBoundingBox(AxisAlignedBox(-100.0*Vector3::UNIT_SCALE, 100.0*Vector3::UNIT_SCALE));
SceneNode* node = mSceneMgr->getRootSceneNode()->createChildSceneNode("Background");
node->attachObject(rect);


for setRenderQueueGroup, i use 2 tipe

rect->setRenderQueueGroup(RENDER_QUEUE_OVERLAY);
rect->setRenderQueueGroup(RENDER_QUEUE_WORLD_GEOMETRY_1);


Is there any particular reason why you dont use overlays?

i don't know how to change from one overlay to another overlay.
and i use that because i have so many menu in my game.
so using that, it make easier for me

Probably it would be easier if you use overlays (that is their purpose, to show screen ui's)

What do you mean by change overlay to another?

Define overlays in your ".overlay" file, they can be in the same position if you need, then in your application, use the overlay manager to get a pointer to the overlay(s) you want to change using its name (as defined in the .overlay file) hide the overlay and show the other (that way you can change separated overlays)

Or if you need more complex UIs, use any of the several UI libraries for ogre, there are many of them and mostly some will suit your needs

hi, my code is working, here is the mistake

rect->setBoundingBox(AxisAlignedBox(-100.0*Vector3::UNIT_SCALE, 100.0*Vector3::UNIT_SCALE));


and change it to

rect->setBoundingBox(AxisAlignedBox(-100000.0*Vector3::UNIT_SCALE, 100000.0*Vector3::UNIT_SCALE));


thx for the help
