示例1: IsVisible
//----------------------------------------------------------------------------
bool Culler::IsVisible (BoundingSphere const& sphere)
{
if (sphere.GetRadius() == 0.0f)
{
// The node is a dummy node and cannot be visible.
return false;
}
// Start with the last pushed plane, which is potentially the most
// restrictive plane.
int index = mPlaneQuantity - 1;
unsigned int mask = (1u << index);
for (int i = 0; i < mPlaneQuantity; ++i, --index, mask >>= 1)
{
if (mPlaneState & mask)
{
int side = sphere.WhichSide(mPlane[index]);
if (side < 0)
{
// The object is on the negative side of the plane, so
// cull it.
return false;
}
if (side > 0)
{
// The object is on the positive side of plane. There is
// no need to compare subobjects against this plane, so
// mark it as inactive.
mPlaneState &= ~mask;
}
}
}
return true;
