In the code, the data structure that holds the 3D image and vertex buffer used for communicating between the steps of the marching cubes algorithm is called McubesChunk, implemented in mcubes_chunk.cpp. We allocate on startup a pool of MCUBES_CHUNK_COUNT-many such structures, held in g_...

Semaphore is a kind of mechanism used in a multithreaded environment to ensure that two or more key code segments are not concurrently invoked. In order to enhance the response capability of real-time operating systems, a hardware design scheme to implement semaphore management based on field progr...
