#P5846. Convex Hull

Convex Hull

Problem Description

There are n points in three dimensional space.

Consider the convex hull of n points.

Given a plane, you should work out the area of section of convex hull by the plane.

Input

First line contains T(T <= 10), a number of test cases.

For each test case, there are two integer n and m, number of points and number of queries.

Next n lines contains three integers x, y, z, coordinate of point.

Next m lines contains four integers a, b, c, d, specifying the equation of plane: ax + by + cz + d = 0.

1 <= n <= 1000
1 <= q <= 1000
Absolute values of x, y, z, a, b, c and d are not greater than 2000.

Output

For each test case, first line contains “Case #x:”, x is the number of the case.
For each query, you should print one float number in three decimal places in one line.

1 6 1 0 0 1 1 0 1 0 1 1 0 0 -1 1 0 -1 0 1 -1 0 0 1 0
Case #1: 0.500
