Precise Design of Solid Rocket Motor Heat Insulation Layer Thickness under Nonuniform Dynamic Burning Rate

Procedure 2

Parallel distance querying.

Input: Triangle set , sampling point set

1: Build a AABB tree object from

2: for all sampling sections serial do

3: Fetch all sampling points on from

4: Initialize resulting array

5: for all fetched sampling points parallel do

6:  Query the minimum distance to the AABB tree object, store the result into

7: end for

8: Perform parallel reduction to find the minimum distance from

9: end for

10: return all computed minimum distances.
