ABSTRACT: This article presents a new contact resolution algorithm for 3D DDA. In the new algorithm, two-stage contact definitions named as geometric contact and structural contact are proposed to find contact point and contact plane. Then, rounding scheme which installs the virtual spheres and cylinders into the contacting vertices and edges is applied to the algorithm. Examples are provided to verify the workability of new contact algorithm.
