// FrustumTest
//
//	template class FrustumTest<T>
//
// This is a helper class, designed to accelerate the case
// where many tests are made against the same frustum.
// That's a really common case.
//
// The acceleration is achieved by pre-computing the planes of
// the frustum, along with the ablsolute values of the plane normals.
//

//////////////////////////////////////////////////////////////////
// How to use this
//
// Given that you already have:
//    Imath::Frustum   myFrustum
//    Imath::Matrix44  myCameraWorldMatrix
//
// First, make a frustum test object:
//    FrustumTest myFrustumTest(myFrustum, myCameraWorldMatrix)
//
// Whenever the camera or frustum changes, call:
//    myFrustumTest.setFrustum(myFrustum, myCameraWorldMatrix)
//
// For each object you want to test for visibility, call:
//    myFrustumTest.isVisible(myBox)
//    myFrustumTest.isVisible(mySphere)
//    myFrustumTest.isVisible(myVec3)
//    myFrustumTest.completelyContains(myBox)
//    myFrustumTest.completelyContains(mySphere)
//

//////////////////////////////////////////////////////////////////
// Explanation of how it works
//
//
// We store six world-space Frustum planes (nx, ny, nz, offset)
//
// Points: To test a Vec3 for visibility, test it against each plane
//         using the normal (v dot n - offset) method. (the result is exact)
//
// BBoxes: To test an axis-aligned bbox, test the center against each plane
//         using the normal (v dot n - offset) method, but offset by the
//         box extents dot the abs of the plane normal. (the result is NOT
//         exact, but will not return false-negatives.)
//
// Spheres: To test a sphere, test the center against each plane
//         using the normal (v dot n - offset) method, but offset by the
//         sphere's radius. (the result is NOT exact, but will not return
//         false-negatives.)
//
//
// SPECIAL NOTE: "Where are the dot products?"
//     Actual dot products are currently slow for most SIMD architectures.
//     In order to keep this code optimization-ready, the dot products
//     are all performed using vector adds and multipies.
//
//     In order to do this, the plane equations are stored in "transpose"
//     form, with the X components grouped into an X vector, etc.
//
