示例1: getIntersectionTime
float MapTree::getIntersectionTime(const Ray& pRay, float pMaxDist, bool pStopAtFirstHit)
{
double firstDistance = inf();
const IT end = iTree->endRayIntersection();
IT obj = iTree->beginRayIntersection(pRay, pMaxDist);
for ( ;obj != end; ++obj) // (preincrement is *much* faster than postincrement!)
{
/*
Call your accurate intersection test here. It is guaranteed
that the ray hits the bounding box of obj. (*obj) has type T,
so you can call methods directly using the "->" operator.
*/
ModelContainer *model = (ModelContainer *) (*obj);
float t = model->getIntersectionTime(pRay, pStopAtFirstHit, pMaxDist);
// just for visual debugging with an external debug class
#ifdef _DEBUG_VMAPS
if(gCount3 == gCount1)
{

testBox = model->getAABoxBounds();
gBoxArray.append(testBox);
