示例1: isFullyVisible
/* special function that returns true only when sphere fully fits inside the frustum. */
bool PCZFrustum::isFullyVisible(const Sphere& bound) const
{
// Check originplane if told to
if (mUseOriginPlane)
{
if (mOriginPlane.getDistance(bound.getCenter()) <= bound.getRadius() ||
mOriginPlane.getSide(bound.getCenter()) != Plane::POSITIVE_SIDE)
{
return false;
}
}
// For each extra active culling plane,
// see if the sphere is not on the positive side
// If so, object is not fully visible
PCPlaneList::const_iterator pit = mActiveCullingPlanes.begin();
while ( pit != mActiveCullingPlanes.end() )
{
PCPlane* plane = *pit;
if (plane->getDistance(bound.getCenter()) <= bound.getRadius() ||
plane->getSide(bound.getCenter()) != Plane::POSITIVE_SIDE)

return false;
