| Summary | 0024050: Voxel_FastConverter::Convert / ConvertUsingSAT - problems in multithreaded scenario | ||||
| Description | Both methods mentioned above use the following code to judge which triangles to process in the specified thread: start_thread_triangle = (ithread - 1) * (myNbTriangles / myNbThreads) + 1; end_thread_triangle = (ithread - 0) * (myNbTriangles / myNbThreads); That code gives incorrect results for some cases due to the fact that the computation is carried out on integer numbers, e.g.: myNbTriangles = 12; //Box myNbThreads = 8; (myNbTriangles / myNbThreads) always yields 1 and so the triangle 9 to 12 are never processed. | ||||
