BVH sample

[QsingHuan]

in assignment 7, when sample on BVH

GAMES101-HW/hw7/BVH.cpp

Line 167 in b53fe64

float p = std::sqrt(get_random_float()) * root->area;

the code use std::sqrt(get_random_float()) instead of uniform distribution to sample on the area, but i can't understand the reason for doing this. Is this a bug?

@QsingHuan There are some designs in get_random_float which are specific for parallelism. You may refer to get_random_float for these designs in detail.
