Fig. 4From: Marching cubes technique for volumetric visualization accelerated with graphics processing unitsOur method for acceleration of the marching cubes algorithm. Stages 1 and 2 are responsible for the preprocessing stage; stages 3 to 5 correspond to the execution of marching cubes and stage 6 makes the display of vertices on the screen. Green boxes stand for the actions executed on CPU, whereas the orange boxes the ones on GPUBack to article page
