A POSITION SENSOR FOR COMPUTER MODELING

对于大分子结构和分子相互作用的研究， 使用计算机生成的分子显示是一种强大的 解释工具。 特别是，能够操纵 空间，即旋转和平移分子到任何期望的位置。 定向增强了装置的有用性。 更进一步的 复杂性在于提供反馈机制， 排斥力或吸引力（货车范德华相互作用）表现为 两个分子结合在一起，或者单个分子扭曲成一个 新构象 已经设计了操纵杆装置来提供这些 功能. 两个分子或同一分子的一部分可以旋转 翻译成任何方向。 随着每一个新的位置，计算机 程序重新评估适当的力量，以提供调查员 感受一下所涉及的全部力量。

For the study of macromolecular structure and of molecular interactions, the use of a computer generated display of the molecule is a powerful interpretive tool. In particular, the ability to be able to manipulate in space, i.e. to rotate and translate the molecule(s) to any desired orientation enhances the usefulness of the device. A further degree of sophistication is to provide a feedback mechanism giving an indication of the repulsive or attractive forces (Van der Waals interactions) present as two molecules are fitted together or as a single molecule is twisted to a new conformation. A joy stick apparatus has been designed to provide these features. Two molecules or part of the same molecule can then be rotated and translated in any direction. With each new position, the computer program re-evaluates the appropriate forces to provide the investigator with a feel of the total forces involved.
