I am using setRenderingDistance on my ManualObject on a low distance. Odly the objects on the right disappear if I go left with my camera. So its applied to the wrong objects. Could anyone post how to deal with setRenderingDistance?
my manual objects:
Code: Select all
mManualObject->begin(mMaterial, Ogre::RenderOperation::OT_TRIANGLE_LIST);
//populate
mManualObject->end();
mManualObject->setRenderingDistance(100);
my camera:
Code: Select all
camera->setNearClipDistance(5);
camera->setFarClipDistance(99999 * 6);
camera->setUseRenderingDistance(true);
camera movement:
Code: Select all
//capture keyboard and move the player accordingly
OIS::Keyboard* keyboard = OgreFramework::getSingletonPtr()->m_pKeyboard;
int forward = (keyboard->isKeyDown( OIS::KC_W ) ? 0 : 1) + (keyboard->isKeyDown( OIS::KC_S ) ? 0 : -1);
int leftRight = (keyboard->isKeyDown( OIS::KC_A ) ? 0 : 1) + (keyboard->isKeyDown( OIS::KC_D ) ? 0 : -1);
//there seems to be some movement, so move the cams
if (forward !=0 ||leftRight != 0)
{
//get direction of cam
Ogre::Vector3 dirX = camera->getDerivedOrientation();
Ogre::Vector3 dirZ = camera->getDerivedOrientation();
//update camera position
camNode->setPosition( camNode->getPosition+ dirZ * forward * timeSinceLastFrame * PLAYER_SPEED
+ dirX * leftRight * timeSinceLastFrame * PLAYER_SPEED);
}
Is it a problem that I update the position of the camNode and not the camera itself?
Thanks!

That sounds correct. If you move the camera left then objects on the right will get further away. As soon as they are further than the rendering distance you set, they will stop rendering.

I would expect it to apply to distant objects also. So it would react like a clipping plane. But it doesn't.
