Abstract: Marching cubes algorithm of surface rendering of solid rocket motor ICT volume data was researched. 3D grid model composed by large number tri patches of solid rocket motor was obtained. According to the characteristics of 3D grid model of solid rocket motor, cutting tool simulation, collision detection, path definition, mesh reconstruction and extract method were investigated. Interactive cutting operation to 3D grid model of solid rocket motor was realized. The grain and debonding part of standard testing motor were reshaped. The triangle patches of the sections were reconstructed. The results of the reshaping show that the crack of the model can be reshaped by sphere cutting tool and the debonding part can be reshaped by cylinder cutting tool. The dimensions of the cutting tool can be adjusted to the dimensions of defects. Both of the sections after being reshaped were smooth. ©, 2015, Journal of Solid Rocket Technology.
