示例1: cubeInKeyhole
// A box is inside a sphere if all of its corners are inside the sphere
// A box intersects a sphere if any of its edges (as rays) interesect the sphere
// A box is outside a sphere if none of its edges (as rays) interesect the sphere
ViewFrustum::location ViewFrustum::cubeInKeyhole(const AACube& cube) const {
// First check to see if the cube is in the bounding cube for the sphere, if it's not, then we can short circuit
// this and not check with sphere penetration which is more expensive
if (!_keyholeBoundingCube.contains(cube)) {
return OUTSIDE;
}
glm::vec3 penetration;
bool intersects = cube.findSpherePenetration(_position, _keyholeRadius, penetration);
ViewFrustum::location result = OUTSIDE;
// if the cube intersects the sphere, then it may also be inside... calculate further
if (intersects) {
result = INTERSECT;
// test all the corners, if they are all inside the sphere, the entire cube is in the sphere
bool allPointsInside = true; // assume the best
for (int v = BOTTOM_LEFT_NEAR; v < TOP_LEFT_FAR; v++) {
glm::vec3 vertex = cube.getVertex((BoxVertex)v);
if (!pointInKeyhole(vertex)) {
allPointsInside = false;
break;
}
