// collides with any other bounding boxes?
bool
Agent::intersects(Ogre::Entity* e)
{
if (e == NULL) { return false; }
Ogre::AxisAlignedBox mBox = mBodyEntity->getWorldBoundingBox();
Ogre::AxisAlignedBox eBox = e->getWorldBoundingBox();
return mBox.intersects(eBox);
}示例2:
bool
Agent::intersectsSphere(Ogre::Entity* e)
{
if (e == NULL) { return false; }
Ogre::AxisAlignedBox mBox = mBodyEntity->getWorldBoundingBox();
//Ogre::Real radius= e->getBoundingRadius();
Ogre::AxisAlignedBox eBox = e->getBoundingBox();
//e->getWorldBoundingSphere
e->getBoundingBox();
return mBox.intersects(eBox);
}示例3: _convertOgreEntities

}示例4: isInLightRange
//-----------------------------------------------------------------------
bool Light::isInLightRange(const Ogre::AxisAlignedBox& container) const
{
bool isIntersect = true;
//Check the 2 simple / obvious situations. Light is directional or light source is inside the container
if ((mLightType != LT_DIRECTIONAL) && (container.intersects(mDerivedPosition) == false))
{
//Check that the container is within the sphere of the light
isIntersect = Math::intersects(Sphere(mDerivedPosition, mRange),container);
//If this is a spotlight, do a more specific check
if ((isIntersect) && (mLightType == LT_SPOTLIGHT) && (mSpotOuter.valueRadians() <= Math::PI))

Quaternion localToWorld = Vector3::NEGATIVE_UNIT_Z.getRotationTo(mDerivedDirection);

//Helpful for when the light is at an angle near one of the vertexes of the bounding box
