发帖数: 31659 | 3 The blog is mainly about numerical computation.
========================================
Precalculate T number of random triangles so that all points of the
triangles lie on the surface of the unit sphere.
Precalculate R number of random rays so that each ray goes through two
points randomly selected on the surface of the unit sphere.
Intersect each ray with the whole set of triangles, so there will be R &#
10005; T intersection tests in total.
========================================

Of course the "If" is still questionable.

如果是cpu-bound，没有多线程，速度就比不上jvm了。

发帖数: 31659 | 7 As I quoted earlier, the Blog used numerical examples to do the test and
that is why I think it is impressive.
Below is the step 1 of the test:
"
Precalculate T number of random triangles so that all points of the
triangles lie on the surface of the unit sphere.

cpython是啥情况 |
