Enhancing graphical objects whose behaviors are governed by the laws of physics is an important requirement in modeling virtual physical environments. In such environments, the user can interact with graphical objects and is able to either feel the simulated reaction forces through a physical computer interface such as a force feedback mouse or through such interactions, objects behave in a natural way. One of the key requirements for such interaction is determination of the type of contact between the user controlled object and the objects representing the environment. This paper presents an approach for reconstructing the contact configuration between two objects. This is accomplished through usage of the time history of the motion of the approaching objects for inverse trajectory mapping of polygonal representation. In the case of deformable objects and through usage of mass-spring-damper system this paper also presents a special global filter that can map the local deformation of an object to the adjacent vertices of polygonal mesh. In addition to offering a fast computational framework, the proposed method also offers more realistic representation of the deformation. The results of this paper are shown through detailed examples and comparison analysis using different computational platforms.

Insect Attack

Rattan on frequently attacked by the powder post beetle (Tellu, 2001). The prevention of dry powder attacks is done by preservation. The increasing resistant of rattan from insect attack can be done by an environmentally friendly preservative, the Galam wood vinegar. This research aims to determine the most effective concentration of preservative that shows the lowest attacks level of D. Farb minutus powder. The rattan used is green rattan (Calamus sp.) The concentration of preservative that are used:10%, 40%, 70% and 100%. The testing of dry powder attack used force feedback method. The effectiveness test parameters of wood vinegar to dry powder attacks included degree of protection Dinoderus minutus Farb. powder, reduction percentage of rattan weight and the mortality of dry powder Dinoderus sp for toxicological testing of wood vinegar. The test results showed that the degree of protection powder in rattan growing along with the increased concentration of preservatives. The higher the concentration of wood vinegar, the smaller the reduction of rattan weight and the higher the mortality rate of dry powder. Keywords: resistant of rattan, wood vinegar, Dinoderus minutus.
