back to boardCan you give some tests? The stars coordinates aren't natural numbers? Why precision of 10^-5 is needed? Should the algorithm ignore cases when scalar product of normal vector of the plane and "star"-vector is negative (the angle between vectors will be 90<x<270 so star's rays won't reach solar battery of esp. this plane)? Integer output also works, but you need int64_t.
Note that it is not enough for normal/star angle to be less than pi/2, you also need to have correct normal -- the one that is opposite to the fourth vertex. |
