{
for (auto r : m_roots)
{
Sphere worldBounds = r->totalBounds();
worldBounds.transformBy(r->worldTransform());

nodes.push_back(r);
}
}示例2: test
void test(){
Sphere s = Sphere((vec3) {0.,0.,0}, 5., (Color) {100, 100, 100});
Intersection i = s.intersects((vec3) {0,0,-10}, (vec3) {0,0,1});
assertEqual(i.distance, 5., "Intersection distance");
assertEqual(i.point, (vec3) {0,0,-5}, "Intersection point");
assertEqual(i.normal, (vec3) {0,0,-1}, "Intersection normal");
assertEqual(i.obj, &s, "Intersection object");
